Lol pretty much what the movie was about: Dinosaurs fighting Dinosaurs. Dinosaurs fighting people. People freaking out as dinosaurs kill people. The visuals helped a lot too. I liked the environments and the setting they created. It was just a nice change from what the last few JP movies were but still managed to roll with the same idea as the other ones.
Plus I'm always a sucker for putting nostalgic callbacks to older entries in franchises =P
