Ignore the naysayers... GO!
Just got home from Avatar. What an awesome film! Easily the best CG effects ever. A well written plot that really fleshes out (literally) all the characters. One of the shortest 2 1/2 hour movies I've ever been to. The film may seem to preachy about the raping of the planet but that's what the humans are doing in this film, so from that perspective the film is right on the mark.
Look, I'm a conservative guy, but anybody who whines about this film being " too political" is quite simply too jaded and probably wouldn't like Disneyland either!
Go see the film on the big screen as it was intended... you'll never get the same feeling at home on your big screen tv.
Just GO!!
