The Lost World - Jurassic Park
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.--Tom Keogh

Jurassic Park III
Surpassing expectations to qualify as an above-average sequel, Jurassic Park III is nothing more or less than a satisfying popcorn adventure. A little cheesier than the first two Jurassic blockbusters, it's a big B movie with big B-list stars (including Laura Dern, briefly reprising her Jurassic Park role), and eight years of advancing computer-generated-image technology give it a sharp edge over its predecessors. While adopting the jungle spirit of King Kong, the movie refines Michael Crichton's original premise, and its dinosaurs are even more realistic, their behavior more detailed, and their variety--including flying pteranodons and a new villain, the spinosaurus--more dazzling and threatening than ever. These advancements justify the sequel, and its contrived plot is just clever enough to span 90 minutes without wearing out its welcome.
