A fossilized skeleton pried from the earth in southern California, and dating as far back in history as 1993, reveals this new blockbuster to be not a sequel but a remake. Notice the similar spinal formation: two kids venture into the title theme park to experience the wonder of cloned dinosaurs, but all hell breaks loose. Chris Pratt, whose action-hero insouciance harks back to Errol Flynn, stars as a dino trainer at the park who goes in to rescue the kids and tangles with an especially wicked mutant dinosaur; Bryce Dallas Howard plays the kids’ aunt, a park administrator who must be ritually taught that man shouldn’t meddle in things he doesn’t understand. The characters are all paper-thin, but that doesn’t matter because their sole purpose is to get chomped. Colin Trevorrow directed; with Vincent D’Onofrio, Judy Greer, and Irrfan Khan.
