Didn't I already see this movie before?

Rating: 1/10 (6 March 2010)

With all the hype about this movie, who could resist the temptation? Well, I ate the apple and was punished.
The plot: Somebody was on a mission to subvert an alien tribe; instead, he became assimilated and turned into a fighter for them. Doesn't this ring Dances With Wolves?
To send this person to the other world, push a button. Didn't they do the same in a little-known movie called Matrix?
Haven't we seen plenty of flying dragons in the Lord of The Rings? How come you Mr. Cameron didn't think of making the trees on Pandora walk and kill the Sky People. That would have been so original!
And so many people gave this movie such high ratings. Obviously, while computers become more intelligent, humans are dumber.
