Not incredible, but not bad. The movie is actually really good, amazing special effects and performances. The story is light years better than the first movie, and although Edward Norton has an incredible performance (do you expect any less from him?) I seriously missed Eric Bana.
Prepare to have fun with this movie, and enjoy that last fighting scene.
The movie is great, low in action, but packed with story and great performances. Trust me when I say this movie is great! Stay after the credits, there's a little scene that if you are a Marvel fan, you will love!
