I just saw Avatar in 3D and it is, you know--about what you'd expect. All the critics are saying it's an unspectacular movie with spectacular visuals but I personally found the visuals gross. I almost couldn't stand it. Here is a list (by no means exhaustive) of things I hate that Avatar contains:
Giant Blue Sigourney Weaver in Cut-Off Tank Top
I kept thinking the aliens' legs on Pandora looked like pants that David Lee Roth would wear. It distracted me from the subtle messages about the Iraqi war and environmentalism that James Cameron was trying to communicate to me through nuance.
Anyway, I understand why people like this movie but no matter how much you might want to go into World of Warcraft and mate for life with your virtual girlfriend, James Cameron can't make it happen--not even with 500 million dollars.
