Blood Mirrors: How I Saw the Devil, Cold Fish, and Revenge Redefine the Horror of Retribution


“Revenge reveals the darkest reflection we hide within.”

Horror cinema has long functioned as a reflective surface, exposing humanity’s deepest fears, desires, and moral uncertainties. The films I Saw the Devil (2010), Cold Fish (2010), and Revenge (2017) serve as “blood mirrors,” revealing not merely the visceral violence inflicted upon their characters but also the profound psychological and ethical transformations that vengeance ignites. Emerging from South Korean, Japanese, and French cinematic traditions, respectively, these works reconceptualize the trauma of retribution into nuanced explorations of identity, power, justice, and morality. This essay unpacks how such acts of revenge fracture and distort the avengers themselves—blurring the boundary between hunter and hunted—and challenge audiences to consider the complicated ethics of vengeance.

Becoming the Monster: I Saw the Devil and the Infinite Cycle of Vengeance

Kim Jee-woon’s I Saw the Devil opens with searing loss. Government agent Kim Soo-hyun’s fiancé is gruesomely murdered by the psychopathic serial killer Jang Kyung-chul. Rather than delivering immediate justice, Kim embarks upon a merciless cycle of capture and release aimed not at ending Kyung-chul’s life but extending his suffering to mirror the anguish Kim feels. This circular vengeance becomes a vehicle for exploring grief’s corrosive power, blurring the avenger’s and victim’s identities.

The film’s structure, with its repetitive cat-and-mouse dynamic, becomes a visual metaphor for obsession and moral degradation. With every brutal encounter, Kim sacrifices more of his humanity, evolving into the very monster he’s vowed to destroy. Lee Mo-gae’s cinematography blends stark clinical detachment with visceral brutality; meticulously framed shots contrast vividly with the film’s emotional chaos, compelling the audience into uncomfortable identification with Kim’s dark crusade. The snowy landscapes and cold colors evoke spiritual desolation, emphasizing the film’s existential chill.

Kim’s work transcends procedural thriller conventions by resisting catharsis—vengeance is portrayed not as liberation but endless torment. Critics laud the film for masterfully challenging traditional revenge narratives by suggesting that acts of retribution can perpetuate cycles of violence, consuming both victim and perpetrator. The tension not only lies in physical danger but in the moral disintegration of a man who becomes what he hates.

Hidden Rage Beneath Ordinary Lives: Social Collapse in Cold Fish

Sion Sono’s Cold Fish presents revenge as an eruption of buried rage within the façade of mundane suburban existence. The gentle tropical fish store owner, Nobuyuki Syamoto, leads a restrained, law-abiding life until meeting the domineering and psychopathic Murata. Their relationship becomes a dance of psychological and physical domination, exposing latent violence simmering under cultural conformity.

Unlike the clinical precision of I Saw the DevilCold Fish captures chaos and collapse. Syamoto’s eventual violent revolt is neither heroic nor cathartic but an enactment of existential despair born of oppressive social codes emphasizing politeness, hierarchy, and silence. The oppressive suburban setting becomes almost a character itself—sterile, suffocating, and emotionally barren. The circling fish motif highlights the recursive cycles of repression and violence that trap the characters.

Sono’s cinematic approach balances absurdist, at times black humor with grim horror. This tonal dissonance destabilizes viewer complacency, forcing reflections on how individual suffering is structured and concealed by social and cultural norms. Syamoto’s dissolution challenges viewers to reconsider traditional narratives of justice and victimhood, emphasizing the fragility of identity under systemic pressures.

From Exploitation to Empowerment: Revenge and the Reclamation of Agency

Coralie Fargeat’s Revenge radically revisits the “rape and revenge” genre notorious since 1970s grindhouse cinema. While drawing inspiration from films like I Spit on Your Grave and The Last House on the LeftRevenge rejects those works’ often exploitative male gaze, recasting the survivor’s story through a fully realized lens of autonomy and violent reclamation.

Jen’s transformation—from a sexualized object within a hyper-saturated, colorful visual palette to a mythic force of nature marked by the symbolic phoenix brand—signifies death and rebirth. Fargeat’s use of chiaroscuro lighting, surreal settings, and visceral violence elevates physical trauma to the level of mythic metamorphosis.

This film subverts traditional victim and villain binaries. Jen’s ascent dismantles deeply embedded patriarchal structures, underscoring a reclamation of body, gaze, and power. The climactic chase, drenched in blood and primal energy, becomes a ritualistic unshackling rather than mere revenge. Through this revival of grindhouse aesthetics, Fargeat forges a new grammar of feminist survival and cinematic empowerment.

Power, Gender, and Hierarchies in Contemporary Revenge Narratives

These films foreground power dynamics traditionally gendered but reinterpreted here in ways promoting gender-neutral critique. In Cold Fish, toxic masculinity manifests as violent domination versus passivity within strict social codes, both Syamoto’s submission and Murata’s cruelty reinforcing systemic violence.

I Saw the Devil portrays injured masculine pride and control as drivers of vengeance. Kim’s obsession symbolizes fragile protector ideals collapsing into moral ruin. Female characters often exist as symbolic voids, underscoring systemic gender violence and erasure.

Revenge, by contrast, deconstructs these codes. Jen transcends rigid gender norms and victimhood, suggesting power as a fluid, elemental force beyond biology. The film’s desert setting serves as a symbolic womb of transformation, projecting possibilities of autonomy and sovereignty through defiance of hierarchical structures.

National Contexts: Morality, Control, and Crisis

Each film emerges from distinct cultural anxieties and historical trajectories. I Saw the Devil reflects South Korean skepticism about institutional justice amid rapid modernization and lingering traditionalism. Private vengeance becomes a desperate, isolating reaction to systemic failure.

Cold Fish critiques a Japanese culture steeped in social conformity and emotional repression, revealing the violent potential beneath controlled civility. The film reflects post-war tensions and growing awareness of societal alienation.

France’s Revenge draws from the New Extremity movement, blending philosophical and visceral approaches to suffering, reflecting intellectual and artistic responses to modern oppression. Fargeat’s fusion of grindhouse with feminist critique signals contemporary cultural struggle for voices outside dominant systems.

Narrative and Visual Style: Diverse Paths to Transformation

The narrative architectures differ but complement one another. I Saw the Devil’s repetitive structure illustrates cyclical moral decay; Cold Fish depicts downward spiral into absurd chaos; Revenge follows mythic death-and-rebirth arc.

Their visual languages communicate complex ethical positions: Kim’s symmetrical, controlled shots reflect calculated cruelty; Sono’s frenetic, disorienting camera work conveys mental disintegration; Fargeat’s vivid, stylized imagery channels surreal transcendence.

Each film implicates the viewer uniquely. I Saw the Devil seduces with calculated violence; Cold Fish overwhelms with chaotic brutality; Revenge reorients the gaze empathetically to survivor experience. Together, they articulate a profound inquiry into horror spectatorship and ethical engagement.

Societal Reflections: Alienation and Moral Fragmentation

These films manifest collective crises of modernity—gendered hierarchies, failed justice, fractured communities—within intimate personal revenge stories. They diagnose alienation and fragmentation, transforming revenge into language for voicing trauma and injustice. This intersection exposes how power, violence, and identity intertwine in contemporary cultural narratives.

The Horror of Becoming

Ultimately, I Saw the DevilCold Fish, and Revenge frame horror as a meditation on transformation rather than pure evil. Vengeance reshapes the self, often toward destruction. Kim becomes the hunted devil; Syamoto lives his oppressor’s violence; Jen transcends human limits through fiery renewal.

Together, they depict revenge as curse, collapse, and painful rebirth—a global meditation on violence and selfhood. Their shared revelation: revenge unmasks the darkness dwelling quietly within us all, proving that horror’s deepest mirror reflects ourselves.

Horror Review: Cold Fish (dir. by Sion Sono)


“Life is pain.” — Nobuyuki Syamoto

Unflinching, subversive, and dripping in corrosive dark humor, Sion Sono’s Cold Fish (2010) doesn’t just showcase Japan’s taste for genre-bending horror—it rips open the underbelly of polite society and exposes what writhes beneath. If I Saw the Devil was a descent into the abyss of revenge, Cold Fish is a fever-dream trek through manipulation, depravity, and the most repressed corners of the psyche. Built around the crucible of violence and sex, Sono’s film dares viewers to question not only the shape of evil, but whether the forces that awaken it could be lurking in anyone.

Before Cold Fish, Sono had already established himself as a subversive force in horror with his earlier film Suicide Club (2001), which helped him gain a loyal cult following and introduced him to the genre scene at large as an innovative and provocative filmmaker unafraid to challenge conventions. With Cold Fish, Sono refined his style, offering a tighter, more psychologically driven narrative that accelerates the intensity while probing deep societal anxieties.

Inspired by the real-life Saitama serial murders of the 1990s, committed by dog breeder Gen Sekine and his common-law wife Hiroko Kazama, Cold Fish draws chilling authenticity from these events. Sekine and Kazama ran a pet shop and poisoned several customers before dismembering their bodies to conceal the murders. Sono reimagines this disturbing history by transforming the pet shop into a tropical fish store and fictionalizing details while preserving the core themes of manipulation, complicity, and violence.

The story opens with Nobuyuki Syamoto, the definition of a beaten-down everyman: a tropical fish shop owner whose daughter openly hates her stepmother, whose marriage is half-drowned in silent resentment, and who drifts through life as little more than a shadow. From the outset, Syamoto’s passivity sets a tremulous undertone—terrible things are happening, but he isn’t doing much to stop them. That changes the moment his daughter Mitsuko is caught stealing and rescued by the charismatic Yukio Murata, proprietor of a flashier fish store. Murata’s manners and generosity are overwhelming, almost caricatured, yet there’s an edge of anticipation: something is amiss, and Sono lets the feeling gradually curdle beneath his gentle facade.

Murata’s initial charm morphs into coercive control as he manipulates the Syamoto family into his orbit. When Syamoto is coerced to become Murata’s “business partner,” the narrative takes its first graphic, kinetic turn: a sales pitch for a rare tropical fish goes lethally wrong. Murata poisons a buyer in cold blood, then erupts into violence, forcing Syamoto and his wife into complicity by helping dispose of the body. The shift is immediate and nightmarish—the performance by Denden (Murata) snaps from quirky salesman to a near-mythical monster, as terrifying for his unpredictability as for his casual approach to killing.

From here, Cold Fish dives into a spiral of murder, sexual domination, and psychological torture. Murata and his partner Aiko have murdered dozens, perfecting the art of erasing their victims. As the body count rises, Sono’s camera remains hauntingly restrained: eschewing frantic cuts for long takes, keeping his characters center-frame, locking viewers in Syamoto’s dread-soaked POV. We are forced to witness every mechanical step in the pair’s routine—the body disposal, the literal scattering of ashes, the casual cruelty.

What makes Cold Fish such a disturbing experience is not merely the gore (though the final act is blood-soaked chaos), but the way deviance is normalized, even made bureaucratic. Murata’s operation feels part nightmare, part dull corporate job. This banality breeds horror. At times, Sono punctuates scenes with black comedy: surf rock tunes play in the background as mutilated bodies are processed in Murata’s shop, and his wife’s participation has a twisted, deadpan humor that makes the violence doubly unsettling.

Syamoto’s trajectory is the film’s secret weapon. By trapping us in his perspective, Sono draws out the uncomfortable reality of learned helplessness, craven compromise, and the latent violence beneath a repressive facade. Syamoto isn’t a hero or anti-hero, but a study in desperation and dissolution. His initial submission slowly ferments into rage, and when he finally snaps, the violence is primal and cathartic—a vengeance that feels less like triumph and more like an act of obliteration. Instead of a neat moral arc, Sono’s script is obsessed with the ambiguity of retribution: what festers beneath apathy, what trauma does when left unaddressed, and what the need to act breeds when suppressed for too long.

This thematic preoccupation connects Cold Fish to the likes of I Saw the Devil: both movies use revenge not as justice, but as a mirror for corruption—how far can the ordinary man go before he becomes indistinguishable from the monsters tormenting him? Sono’s film is ultimately more nihilistic, using social commentary as a subtle undertow, with critiques of Japanese conformity, sexuality, and family decaying beneath the surface. The result is a film that is both emotionally exhausting and intellectually provocative.

Technically, Cold Fish offers Sono at his most focused. The cinematography is subtle but relentless, with natural camera movement amplifying character reactions rather than indulging in spectacle. The use of Mount Fuji as a backdrop for scenes of violence is striking and effective. Costume, color palette, and setting all speak of an ordinary world slowly overtaken by surreal terror. The score plays off these moments, with music choices ranging from nervy tension to surf-rock irony.

The performances are uniformly superb. Denden is magnetic as Murata—making each mood shift obvious, unpredictable, and horrifying. Mitsuru Fukikoshi’s portrayal of Syamoto is raw, fragile, and ultimately explosive. The supporting cast amplifies the film’s extremes without ever feeling cartoonish. Sono pushes them to the edge, finding both tragedy and queasy humor in their unraveling. The sound design, especially in scenes of dismemberment and violence, is overwhelming and intense—forcing the audience into a sensory trap that mirrors Syamoto’s psychological implosion.

Yet Cold Fish isn’t just an exercise in gore or cruelty—it’s an autopsy of repression, cowardice, and compulsion, watched through the lens of a culture known for its traditions of obedience. The film asks what drives people to murder, what keeps them silent, and what happens when those limits are breached. It never gives viewers easy sympathies or clean answers, and the ending is deliberately unnerving—Syamoto’s transformation is complete, but it isn’t heroic, nor is it redemptive.

For some, the film’s length and relentless tone will be too much. Others have pointed out its over-the-top final act, and some feel the excessive violence is hard to justify. However, these very qualities are what cement Cold Fish as a significant work in contemporary Japanese horror—it’s the sort of movie that claws at you for days, sticking in the brain with its grim humor and powerful sense of unease. Like I Saw the Devil, it’s less about catharsis than about exposing the permanent scars left by evil and revenge, and the horrifying possibility that what lurks under the surface of normality is just waiting for an invitation to come out.

Ultimately, Sion Sono’s Cold Fish is an important piece of modern horror—not simply for its brutality, but for its relentless psychological excavation and perverse humor. By channeling the real Saitama serial murders into a study of psychological torment and complicity, Sono creates a film that is designed to provoke, to disturb, and to make audiences ask where the boundaries of morality might finally break. For genre fans, it’s a bracing, unforgettable experience; for those who approach with caution, it’s both a warning and an invitation to glimpse the heart of darkness just beneath the surface.
