The only good part of this movie was the visual effects. The writing is terrible, and the acting (especially Sigourney Weaver) bad. The cursing was all unnecessary. It was preachy (uh-oh, the big bad corporations out to kill the environment for money....) and the "military" was stereotyped as mostly ugly thugs with a bloodthirsty commander. Did anyone else catch the name of the Avatar god? Say it backwards and you have "Yahweh." . It was such a mindless piece of cliche garbage that I hope James Cameron looses his $500 million shirt.
