Funny I just watched Avatar a couple nights ago, and I really did enjoy it. Not for the plot, but visually it is quite stunning. Yeah, I get the American Indian slant, and the evil Warlord/corporation bit. Its a little over the top.

It does seem to me that the whole movie, visually is Roger Dean on steroids. I dont know how Cameron got away with it. but I dont think Roger Dean has a monopoly on things that float in the air.
