Only got Django and Avatar wrong.. haven't seen. I dunno, not big into Tarantino anymore (because I am not longer 16..seems like most of his films are pretty much just phone-ins at this point) and I have never dug James Cameron except for Terminator. His flicks are usually SO CLOSE to being great, but the some ham-fisted shit comes up and everybody lives happily ever after (I wanted to love The Abyss, I really really did).
One of the things I loved about the DVD collector's edition I got was the inside sleeve was covered by critic's blurbs, and there were just as many that were extremely negative as there were positive. I think that's a sign of a good movie when critics don't know what to make of it and are split evenly between hating it and loving it.
