Everyone is so caught up on this whole "the plot is unoriginal" shit that I think it's taking away from the enjoyment that someone might have from watching the movie. For example, when I saw it on opening weekend, all of the negative criticism had not yet started and as such, I went into it not knowing what to expect and came away with an awesome experience. I didn't once think "wow this is so much like Pocahontas" or anything like that. However, now that people have read the criticisms about it, you're already going into it from a negative perspective and will try and validate those claims whenever you can, instead of just enjoying the movie for what it is.
And honestly, even seeing stuff like that picture that Coy posted and reading the bad reviews, I'd still pay $10 to see it again and Ive already seen it 3 times. It's just a damn good movie. Just because it shares plot similarities with something else does not means it's automatically a bad thing. I think it was in the Roger Ebert review that I read where he compared seeing Avatar to the first time he saw Star Wars in the theater. Unfortunately I was not around to see Star Wars at its theatrical release, but I can understand the comparison. It's not like anything else you've seen before.
Of course this is just my opinion, but I know that if I had waited to see it on a tv rather then seeing it in 3D in the theater, I would be hugely disappointed. Matinee showings are a good thing.
