I didn't like it
granted, I watched the 2d version, but I felt it was very "american"
of course the natives are a bunch of nature loving hippies who use bows and arrows
I think it lacked a certain ability to connect with the viewer, and I never felt surprised during the movie in the same way that District 9 surprised me.
Same feeling here. D9 was dark and grimy and kept throwing surprises left-and-right. And the fact that it addresses very human issues (apartheid etc) made it compelling.
Avatar felt like watching a really long Final Fantasy opening scene.
