Great special effects, seamless flow between cgi and actors, was surprised as to how good 3D has gotten. Movie plot was lackluster, reminiscent of Dances with Wolves but not an exact ripoff as some have mentioned. Story had heavy left-winged utopic socio-political views, but that's typical of Hollywood. I think that Lucas would have done a better job on the story though.
As far as those obsessed with the movie...let Darwin get'em! World is already over populated, f-them!
