For five movies, the formula has worked—let dinosaurs loose, and let humans try to escape (or fight) to survive the day. Why, then, writer/director Colin Trevorrow decided to jettison that and instead focus on a mutant locust swarm and a debate about the ethics of human cloning is anyone’s guess. After a comically bad first half, the ship does right itself somewhat for a dino-filled second act, but even the return of Sam Neill and Laura Dern can’t make this anything but the runt of the Jurassic Park litter.
