You laugh at that scene in the movie where Dennis got eaten to death by a small Spitter Dilophosaurus in the jeep, and I have to admit that it *is* kinda funny, especially with that slime ball getting what he deserved; but the novel's Spitter was Jaguar spotted, and twice as big. And of course, there's Nedry's fate IN said novel. ...Let's just say it would've made the JP movie either rated(At best) R, or(at worst) NC-17.
