Avatar, a beautiful 3D world doesn't make up for your 2D story and characters, the overdone message doesen't help either. Hell, the Na'vi were aggressive, holier-than-thou and primitive, the only reason those idiots were around was because unlike having to adapt to the world through evolution, the world was made to baby the little bastards. I wanted to see the space rednecks wipe them out, they may be in it for profit and research, but at least they tried negotiations and trade and aren't as pretentious as the Na'vi. The Native Americans and other native tribes we're in tune with nature, they adapted to their world and learned to survive, the Na'vi can practically dominate the will of other animals and have a bountiful world. They're a babied species that has done virtually nothing and it shows.
Also why the hell were the humans using an open pit mine? They are an advanced species, why don't they have better mining tools?
