The movie seemed to run more with the chaos theory crap Malcom was spouting. Nobody predicted that the fat guy would cut power, that the power would stay off, that the dinosaurs could reproduce, a storm would roll in, t-rex shows up in the main building etc etc.

Lost World was stupid and boring. 3 had the inklings of a decent plot but was poorly made overall. Probably the best of the sequels somehow.
