Does anyone else besides me think that the movie "Avatar" is just "Dances With Wolves" in disguise?

Don't get me wrong, it's highly entertaining, even quite moving in parts. But most of its entertainment value deals with how it looks. The look is everything in this movie, especially if you see it in IMAX 3D. But I think the movie gets absolutely no points for the originality of the story. In my opinion, it almost copies "Dances With Wolves": A man makes contact with a less-civilized foreign culture, realizes that these people are gvery good and love the land and nature very much, becomes enamored with the people and disillusioned with his own people, eventually joining them and even marrying one of them. Then he realizes that his own people are the bad ones and even joins with his new people to fight against them. He even keeps a journal, just like in "Dances With Wolves" . The movie is nothing but "Dances With Wolves." I sure hope "Avatar" doesn't win the Academy Award for Best Picture. "The Hurt Locker" has been named Best Picture by most critics and is more deserving of a win.
