31. The Lost World: Jurassic Park (1997)

Director: Steven Spielberg
Starring: Jeff Goldblum, Julianne Moore, Arliss Howard, Pete Postlethwaite, Richard Attenborough, Vince Vaughn, Vanessa Lee Chester

When Steven Spielberg's Jurassic Park premiered in 1993, viewers gasped with pure awe at the awesome-looking dinosaurs and technical grandeur. Not only were there kick-ass dinos on a big screen, but they looked incredibly real.

By the time Spielberg revisited the well for this tedious sequel, though, the astonishment had worn off; no longer could his and effects designer Stan Winston's dinosaurs carry an entire movie on wide-eyed wonderment alone. But that's what they seemed to be banking on; The Lost World: Jurassic Park features more dinosaurs yet also less excitement and a clunkier story, a watch-the-clock slog not helped by bringing the irritatingly smug Jeff Goldblum back as the sequel's leading man.

If only animatronic dinosaurs had the power to demand script rewrites.
