I don't want to sound too "South Park", but to me, it's way too over-hyped. It seems corny and cliche, and without even seeing the movie, I noticed plot-holes (it's the future where they can transport a man into another living being. They have huge weight-lifting machines and are fighting aliens on a different planet... but they can't fix a crippled guys legs.) Now as i've stated before, i've yet to see the movie, so I'm sure there is some "future" explanation, like Polio-AIDS. James Cameron is an amazing director with billions of dollars worth of notches under his belt, so I doubt this movie will suck, but it's just reusing the same sci-fi elements is all.
