I saw the IMAX 3D version this weekend. No issues here. Concur that it was a comment on many things from a liberal perspective, and played in stereotypes. That's fine with me, I respect people's intelligence to judge accordingly.

I have a lot of sympathy with the theme about trying to impose change on people who don't want it ... although none of their environments are Pandora-esque.

I concur with others that it's a story, well made and told, so lighten up. In general, scifi is one of the most military friendly fiction genres, with almost all space forces being pseudo-military and generally competent/respectable (Star Trek, Babylon 5, Battlestar Galactica (old and new), etc.)
