It was an alright move, but what stops it from being really good is the predictable, run of the mill plot. It's basically "James Cameron Presents Pocahontas". Some of the characters were just bullshit and taken from a book of cliches, especially that American Army guy! "We're tried reasoning with these animals, let's blow the ever living shit out of them!" That and, it really did drag on in parts. I really want to punch anyone who says it's the "LIEK BEST MOVIE EVER!?!!"
Although, I did really enjoy the scenes in the middle in the native land, that was quite a nice experience, especially in 3D.
