Personally, I think that take misreads the film and does not do it justice. Some folks just want to tear down anything popular and feel like their cynicism always gives them a superior take. don't know if you coun't among their number, but I would reconsider.

Neytiri saved Jake, not once, but twice. She saves him when he gets seperated from Norm and Grace. She saves him again when he fights Colonel Miles Quaritch. She's the one that brings the Colenel down, and resuscitates Jake. Yes, Jake rallies all the various "tribes" of Na'vi together, but this comes not from a need for a "white savior" but out of the plot point that he has the inside intel necessary. Largely, even then, he leads them to slaughter and it takes the collective conscience of nature's aid to, er, uproot the alien human invaders.

From a character standpoint, we had dynamic characters whose changes in character were earned. The plot made sense. And the themes, while perhaps heavy handed, nonetheless derived out of a compeling story, well told, and from a technical standpoint, innovative yet masterful. How many blockbusters tackle issues like colonialization, ehtnic strife, scarcity of resources and make it accessable for kids? And how many movies star a handicapped protagonist?
