As a quick note, this movie is overtly anti-war, anti-capitalism and anti-West. Very much a leftist-dogma-driven plot with laughably overdone stereotypes of the main corporate and military personalities. (I mean, geez...the CO actually shows off his battle scars? Ell. Oh. Ell.) There's plenty of info on the plot's politics with a quick google on interviews with James Cameron.

So, if you want to just go see it for the 3D movie technology and to see a very pretty movie with superb action sequences and stunning effects, go for it. If you're dead set against political screeds or if 2 hours of "Iraq was about oil" messages turn you off, it's probably not for you. Personally, I ignored the message and just enjoyed the visuals.

Forewarned is forearmed.

GL and enjoy the movie!
