Avatar - the review by Roger Ebert

The story, set in the year 2154, involves a mission by U. S. Armed Forces to an earth-sized moon in orbit around a massive star. This new world, Pandora, is a rich source of a mineral Earth desperately needs. Pandora represents not even a remote threat to Earth, but we nevertheless send in the military to attack and conquer them. Gung-ho Marines employ machine guns and pilot armored hover ships on bombing runs.

Hmm, sound familiar?
