I managed to see it 2 times in about six hours. Two different groups of friends wanted to see it, and I liked it enough the first time I went again.
The CGI I thought was quite good. Some people say it looked to cartoony, however that was basically because the textures weren't all that detailed. However, since I have never seen a real hulk how do we know exactly what it would look like?
The directing I thought was decent, but the way it kept jumpting between the present, and flashbacks and how you would have 3 different things on the screen at once was very distracting.
It seems everyone either loves it or hates it.
