Those "hating" on Avatar, are you either idiots? Or do you just want to point out the absolute obvious? I think everyone could tell that the plot was cliche, it stunk to high heavens of cliche, but the atmosphere, the graphics, the world, Pandora, you were sucked into it because it was so beautiful and engaging of all your senses, you didn't want to leave.
So if you're going to say that the graphics were amazing(which they were)but the plot has been done before and is cliche, then no shit sherlock, tell us something we don't know.
I saw it in 3D myself and was positively blown away, didn't care that I knew what would pretty much happen, I was lost in the movie all the way through.
