oh dear... James Cameron pulls it off for a second time. You would think Titanic was enough..massive budget, cutting edge effects..childish story. This is basically the Dune story ripped off. However, Dune had a huge story and intricate detail behind the premise of "indigenous people who are at one with the environment overcome technologically advanced but savage invaders intent on destroying the environment for material gain and greed" This is another wafer thin Cameron extravaganza, a po faced, self important cartoon. I found it impossible to suspend disbelief watching this. It fails to convince that the CGI and live action sequences are the same reality, more like Arthur and the Invisibles, where a real world and cartoon world exist alongside each other, or The Matrix, with the characters entering a simulation when they enter the Avatars. From this point, the film can never work. For all the spectacle of the effects, they do not create a convincing reality, merely a luscious cartoon. The greatest majority of cartoons are parody and pastiche, and as such are very funny. Without the humour, this is just a very boring, cringe worthy cartoon. Full marks as always to Cameron for innovation in movie making, and a place in my top ten with T2, but this one is destined to go the same way as Titanic..largely forgotten a year from now. A shame.
