Well since there is no expert who can validate just exactly how the dinosaurs hunted, how do we in fact know that they didn't give a primal scream just before they ate you? In the movie, they did say raptor's hunted in packs, and that the attack usually came from the side from a raptor you didn't even know was there, so maybe the raptor would make noises to get you distracted while his buddies attacked you. I don't know, we may never know, but like others have stated, it's just a movie.
If nothing else, you at least have to like the John Williams score of these movies. Every time we go to Universal in Orlando and get to the Jurassic Park area, I always get goosebumps when walking through the big gates and you start to hear the theme song. Got an email the other day that they were closing river ride, which is too bad, as that was one of our favorite rides.
Did see a list that somebody ranked the movies, and this one came in second to the original. Really? At least the first Jurassic World had a pretty decent dinosaur, and at least had some of the charm of the original. Between JP2, JP3 and this one, I would struggle to rank them, probably tying them all for last.
