My daughter called it "Pocahontas for adults," and I have to agree. The story is predictable and I'm sure many will complain about that. There is ample ammunition in the film for Conservatives to scream about "liberal Hollywood," but the film will stand/fall on its own. I'm not saying this film was meant to send a message -- it is not -- but after the movie, many of the 16-25 year olds I saw in the lobby were talking about it. I think it touched a nerve.
A couple of scenes are meant to evoke emotions from recent events. Cameron and crew capture the look of confusion and despair that are the real human emotions in such a tragedy. That is rare in film.
All in all, I liked the movie. I'm glad I saw it, but I doubt I'd see it again.
