13 Dumb Decisions In Jurassic Park Movies We Can't Forgive
5. Killing The T-Rex - Jurassic Park III
There's nothing wrong with introducing new "villain" dinosaurs to the Jurassic Park franchise. After a while Raptors and T-Rex' would get repetitive, so in Jurassic Park III it was exciting to see a new and terrifying creature take the mantle as the scary, looming threat.
Cue the Spinosaurus; a giant meat-eater with a rad mohawk backbone. This thing was bigger, meaner, and seemed to have a genuine grudge against Alan and the Kirby family. But how does the film establish this thing as being "like nothing we've ever seen before"?
Not it's body count or its big teeth, but by killing a Tyrannosaurus Rex and establishing itself as the new big bad. The T-Rex is the king/queen of Jurassic Park, and JP3 flips the franchise the middle finger by having a fight between the two titans that ends with the T-Rex getting its neck snapped.
Had the movie not included the T-Rex at all, this wouldn't even be a problem. But having this new villain come in and kill the once anti-heroic T-Rex, and not meet a similar fate at the end feels like the franchise never appreciated how much fun the T-Rex was to begin with.
