It's been a while since I checked out of the Jurassic Park franchise, but I get the impression that they really like to headline the Tyrannosaurs and Raptors killing people, and for a little variety I'd like to see some herbivores as the main killers of one movie. Look at pissed off water buffalo or hippo and say that it wouldn't be metal as fuck to have a triceratops or ankylosaur as the main threat of a movie.
