I saw it and liked it very much. I've heard some people didn't like some things about it (special effects, etc.) but to be honest I couldn't pinpoint anything that bothered me. But then my eye is accustomed to CGI now, so 'unnatural' doesn't jump out as much these days. Not to mention I saw the movie solely to be entertained, not to pick holes in a script based on a comic series!
I was very happy with the storyline, and very much appreciated the take that resulted from Ang Lee's research into the Hulk character.
Oh, and the mile high leaping thing was very cool too!
