(spoiler alert)

A lot of the themes and messages in Avatar are very common in science fiction, in particular the parallels with the story of Dune are striking:

- greedy corporation seeks to exploit a resource with little regard for the native population (spice/unobtainium)

- saviour from same race as greedy corporation is accepted into native population and through a mythical prophecy, becomes leader and unites tribes against greedy corporation

- native population and their natural habitat are massively underestimated and through help of saviour defeat greedy corporation
