I put off seeing this as long as I could, but finally got pinned to the wall with my eyelids held open a-la-Clockwork Orange and relented.
This film did not make me want to kill myself, just push James Cameron down a flight of stairs, similar to how I felt after he ruined the mystique of the tragedy of the Titanic. The "look" of Avatar, and the amazing things they have done with CGI are truly amazing.
The rest of the film was pretty much rubbish, IMO. Every scientist wore a white hat. Every member of the military wore a black hat, espoused in grand style by the portrayal of their leader--a glaringly obvious homage to roid rage riddled Vince McMahon, except for the soldiers who had the "courage" to rebel against their own. Cliched, tired, and a story you've heard a thousand times before. But then, I'm reviewing this movie so late the damage is already done--unless it becomes a trilogy.
Two and a half stars. Technical and artistic magnificence torpedoed by juvenile political cliches.
