I like Chris Pratt too, but his character was forgettable. Maybe because it was too perfect, smooth, polished? Alan Grant was a real man, he was plausible as the great paleontologist who has to grapple with a new and strange situation that challenges him both intellectually and physically, and that was part of what made him interesting.
Pratt on the other hand was just this handsome, nice, funny, competent, tough guy who talks to raptors and is basically better than anyone else. He barely interacts with anyone other than the female protagonist and the bad guy, and those interactions are terribly predictable and one-dimensional.
While watching the movie I got the feeling that they were trying to do too many things at once, because some of the side characters were utterly useless and could/should have been sacrificed in favour of more screen time for the main ones.
I'm just going to stop here because I have a lot of problems with Jurassic World.
