Finally saw it today. I enjoyed it. First half of the movie kind of left me wanting more, but by the end I felt like I got more. It felt a little cheesy at times, but that mostly boils down to Spidey's sense of humor. The action scenes were awesome and I loved the atmosphere of the movies, especially the sewer fight and the end scene. Definitely prefer Garfield and Stone over McGuire and Dunst though, by far.
I really enjoyed it, so I'd give it about a solid 8/10. Avengers, for me, was an easy 10/10 and I'm hoping Dark Knight Rises manages to be that good as well.
