In the low tradition of knockoff horror flicks best seen (or not seen) on a drive-in movie screen, Steven Spielberg's sequel to Jurassic Park is a poorly conceived, ill-organized film that lacks story and logic. Screenwriter David Koepp strings along a number of loose ideas while Jeff Goldblum returns as Ian Malcolm, the quirky chaos theoretician who now reluctantly agrees to go to another island where cloned dinosaurs are roaming freely. Along with his girlfriend (Julianne Moore) and daughter, Malcolm has to deal with hunters, environmentalists, and corporate swine who stupidly bring back a big dino to Southern California, where it runs amok, of course. Spielberg doesn't seem to care that the pieces of this project don't add up to a real movie, so he hams it up with big, scary moments (with none of the artfulness of those in Jurassic Park) and smart-aleck visual gags (a yapping dog in a suburb mysteriously disappears when a hungry T-rex stomps by). A complete bust.
