This is amazing! Sorry if I just ruined the movie for you, but this is so incredibly funny (and accurate) I just had to share! I've heard it said that the story is a combination of: Fern Gully, Pocahontas and Dance With Wolves. If you have not yet seen it I think it's worth checking out because the visual effects and animation are stunning, but yeah, the story is definitely not groundbreaking.
Kudos to the dude who came up with the comparison!
