For me it’s unnecessary dinosaur battles. Yes, I’ve heard it ad nauseam: “but it happened in the first film.” Yes, and it felt so much more believable in Jurassic park. A rex vs a pack of raptors that’s it. It didn’t have a Mosasaurus leaping out of the water, or a dinosaur team up to stop a bigger badder threat.
I’m not saying I’m opposed to all dinosaur battles, sure give me raptors hunting herbivores or a rex hunting a triceratops. How cool would it be to see a Spinosaurus fishing for giant fish on the shore while our protagonists try and avoid it?
In all of those cases the dinosaurs feel more believable. They act like animals and less like set pieces. I guess to me dinosaur team ups feel a bridge too far. It takes me out of the film regardless of how “epic” it is. What do you think??
