Yes, that's the biggest and probably most valid criticism not tied to the film's writing or acting. It's pure white savior narrative. Same issue with Last of the Mohicans and a bunch of other movies.

My dad says it's one of the best movies he's ever seen, but specifically because we saw it in IMAX 3D and the graphics were outstanding. Beyond that, he agrees with me that it's just Fern Gully (but without Robin Williams, which instantly makes it worse), which is basically just Disney's Pocahontas.
