Seems really familiar (South Park slams aside). I mean two different races/cultures battling it out over ruling a planet. The film itself relies HEAVILY on AMAZING CGI and computer animation. It all seems so familiar...
Where have I seen this before?
Oh... my... god...

DELGO!!!
Jimmy Cameron ripped off Delgo! He saw the market was unfulfilled by last years movie (would be) king... and struck! What a jerk.
The Delgo creator is gonna be kicking himself... I mean this is EXACTLY what would have happened with a marketing budget!!! (I'm assuming the movie will end up making a few hundred mil)
Anyway... Delgo... we know the truth. And we'll never forget!
