Upon its release in 1993, Jurassic Park set a new standard for onscreen technical wizardry and reasserted Steven Spielberg’s position as the king of blockbuster auteurs. Critics say Jurassic World is a notch or two below that benchmark, but it’s still a pretty fun ride thanks to its appealing (if underutilized) cast and its vast array of suitably terrifying dinosaurs. After a few years of operation, the dino refuge/theme park Jurassic World is losing attendance, so executives have demanded the on-site scientists to develop a bigger, badder creature from the genetic material of a T-rex and a bunch of other prehistoric animals. Will the newly christened Indominus rex drum up more business for the park? Will it eventually escape captivity and wreak havoc? The pundits say Jurassic World isn’t the deepest movie on earth, but it’s sleek, tense entertainment, and a big improvement over the previous Jurassic Park sequels.
