“Everything old is new again.”

How many times have you heard that one? Well, in the case of the just-released (and record-setting in terms of its worldwide box office take) Jurassic World, it turns out that tired old adage is actually quite true, since director Colin Trevorrow has chosen to hew pretty closely to Steven Spielberg’s original model for this fourth installment in the previously-presumed- moribund franchise extrapolated from the works of Michael Crichton. There’s certainly nothing happening here that one could call overtly “new,” per se, but gosh — it’s been so long since Jurassic Park III  that it all just sorta feels new, ya know?

CGI technology has come a long way since the original Jurassic Park  made its debut in 1993, as well, and that’s a big factor — maybe even the biggest factor — in this new flick’s by-popcorn-movie-standards “success,” but don’t think that means I’m damning Jurassic World with faint praise. Truth be told, we just got back from seeing it in Imax 3-D and it’s got pretty much everything you’d ever want in a brainless summer thrill ride : superb effects, likable leads, drama, suspense, tension-cutting humor, nicely despicable (sorry, does that even make sense?) villains, and mile-a-minute thrills. My wife and I both left the theater smiling and I ain’t ashamed to admit it.

My only real gripe is one that I knew I’d have going in — Jurassic World continues the morally-questionable trend established at the series’ outset of using kids placed in danger (in this case brothers Zach and Gray, played by Nick Robinson and Ty Simpkins, respectively) as its primary focus/narrative crutch, with benevolent adults coming in to save the day (here represented by Chris Pratt’s  “dinosaur wrangler” character Owen, and Bryce Dallas Howard — who, goddamit, Hollywood is bound and determined to make a star out of yet! — as their hitherto- inattentive aunt Claire, who’s one of the park’s big-wigs), and I’m sorry, but if you don’t know why that scenario is inherently creepy to some of us, then you haven’t been paying much attention to the some of the uglier and more salacious rumors about Spielberg’s personal life that have been swirling around for decades now. And that I won’t repeat here. So let’s just move on, shall we?

In any case, that solitary-but-predictable qualm aside, the fact of the matter is that Jurassic World is expertly-crafted throwaway fun. Not every movie needs to re-invent the wheel to stand out, and Trevorrow wisely has that figured from the outset here. All we want from his big-budget extravaganza is pretty much the same sort of story that had us jumping in our seats all those years ago, and to feel the same sort of “rush of excitement” that we did back then and which the two previous installments in the series just weren’t able to capture. It’s a dinosaur movie, for Christ’s sake, so just give us a shit-load of dinos on the loose and we’re gonna be happy! How hard is that to figure out?

About the only  wrinkles to the formula here are the introduction of the new genetically-engineered “super-dinosaur” Indominus Rex, and the hare-brained scheme laid out by the villainous Hoskins (Vincent D’Onofrio) to train Velociraptors to be — uhhmmm — super-soldiers for the US army. But rich people with more money than sense employing unscrupulous lackeys and amoral scientists have been a Jurassic staple, in one form or another, from jump, and one might even argue that really smart people doing really dumb things has always been at the heart of these flicks. That’s okay with me if the end result is admittedly disposable fare done with this much gusto, flair, and panache. There are a million and one reasons to write off Jurassic World as derivative, senseless garbage,  sure — but when you’ve got five or six bloodthirsty dinosaurs battling it out for supremacy at the end, I don’t care about any of those intellectual (or, as is more often the case, pseudo-intellectual) arguments. I’m just having a damn good time.
