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.
