The Incredible Hulk - 8/10
I am fairly impressed by Marvel Studios right now. They have hit two movies out of the ballpark with Ironman and the retcon of Hulk. I guess it will take a very big miss of a movie for me not to watch anything they put out in the near future.
Norton was excellent as Bruce Banner. The CG was pretty good, and the fight scenes (specially the final fight scene with Hulk vs. Abomination) was very well done and was paced really well.
They have now laid the groundwork for Captain America and The Avengers Film by releasing two good movies in Ironman and The Incredible Hulk. If you're interested in watching The Avengers Film two/three years from now, this is definitely a must-see.
