This is a terrible comparison because humans are not a natural food source for dolphins and killer whales. You can jump into a crowd of wild dolphins/killer whales and they will not eat you or view you as a food source.
Raptors are different because they were the apex predator on land and everything was viewed as a food source.
Back to the movie though, say the trailer again, looks like hot garbage.
Especially the part when them winged dinosaurs were lifting them people out of the park. They honestly need to make a R rated version of this movie, it would be so much better.
Well then idk what to tell you
. All of this is building on ideas and concepts from the first movie and the first book. The scientists at ingen have gone beyond anything Hammond could've dreamed of and they've done something that Malcolm and dr grant said could not be done. I'm assuming if you look back in time way before we were born or even thought of, people said lions and tigers couldn't be trained either; no way the king of the jungle could be domesticated but I can pick any zoo in the country and go look at one if I want and even see them get fed
Eagles descended from Raptors, used to eat humans. 
). The way it could work in the movie is, maybe the frankenstein raptor killed their raptor leader or some shyt.
And the raptors and the humans work together that way to kill it.
