Oh, I didn't mean to imply you said that. I agree though, the protagonists aren't really heroes at all. One of the reasons I love Grant. He really puts other peoples safety before his, especially Ellie and the Kids. Sure, he's a bit grumpy during the first half of JP3, but during the second half he's risking his life for other people again. Like during the Aviary sequence and when the Spinosaur attacks the boat.
Man, the more I think about it the more annoyed I get with JP3. It really had some awesome ideas, like the two I mentioned before and getting chased by Raptors through the stampede. But everything just felt poorly executed to me. For every good idea, there were two stupid pointless ones.
