Good that the movie showed how evil mining corporations bulldoze sites sacred to cultures they don't care about or understand (ref. Uranium extraction, oil drilling, Bhopal, etc.) Nice that the lead characters were allowed time to develop within and beyond the spectacular imagery. Unfortunate, violent battle full of Hollywood explosions, deaths and impalements - don't take any kids under 13 to see this movie. Zero tobacco would be allowed in space travel, so Sigourney Weaver's character puffing away was just ridiculous. 2D version reportedly better than 3D, because of brighter, clearer pictures, not having to wear glasses, and fewer distractions thrusting out of the screen.
