While I’m more for musical comedy than scifi, I was not offended by the logic of the plot.

I came away with the impression the levitating mountains and intense magnetic field were artifacts of the valuable mineral “unobtainium”, buried below the giant Home Tree. Humans must depose Native life and The Great Tree Spirit to get the goods. (Just as we westerners must depose fundamentalist Islam to get the petroleum Allah, as a practical joke sequestered mostly under Muslim lands.)

Yes, the Noble Natives could “benefit” from human science and technology. The greedy but nt totally cluelss Corporation sends in a more or less moral Anthropologist-led Science team to broker a peaceful deal. They make the attempt using part-human, part Native biological chimeras in the form of remotely-controlled Avatars. Of course, the Corporate Managers and their Military Corps see the Avatars merely as useful spies.

Our legless hero, through a fortunate accidental meeting with their Pocahontas, gets accepted by the Noble Natives. Predictably, he flips to the Native side, along with the Anthropologist. [Her cigarette-smoking was the only thing in the movie that offended me!]

At this point in the movie, I knew the Natives would beat the Evil Corporate Militarists. However, I expected the totally connected roots of the neuron/brain-like Spirit of All Trees to play a more direct role. I guess it did so indirectly as all the wild animals suddenly became tame enough to help defeat the humans.

At the end, as a reward for his good behavior, our formerly legless hero’s Avatar becomes self-sufficient and a real Native. (The puppet Pinocchio becomes a real boy.) He’ll mate with the Natives and, in a couple generations, they’ll come to the humans with a win-win business deal for “unobtainium” and the tourist trade?
