Seen Avatar? It is outstanding and astonishing. That's the first and last thing to say about it.

As to the politics, it's clearly about the environment, though I wouldn't be cheering if I was an environmentalist. The film offers catharsis for the ruining of the rain forest. It almost certainly says to viewers, 'you were moved, you've shown remorse - and now you can carry on as before, as it's only a fantasy movie.'

I felt that the 3D was a limited success. There is this strange layering effect it induces, which looks like a variety of hyperreality rather than the real world. My guess is it'll work well for fantasies, but not for other genres, where it'll be a distraction. Also, it's a strain on the eyes.

The thing that anyone interested in philosophy is bound to contemplate is the number of different, and incompatible, philosophies of mind the film incorporates. Cartesianism abounds, in the avatar bodies that must be animated by external minds. Computer, brain-centric models do too, in the 'plug and play' firewire with which Pandora's lifeforms come equipped. There're clear moments of panpsychism, via the comments about the energy that flows through all things. And there are hints of externalism, as contrary to the computer model, Jake Sully can't just be uploaded with knowledge of how to excel as a warrior, but he must learn it by being in the world.
