I just saw the movie a few days ago. Overall, I thought it was overrated. Although, the Kirsten Dunst scenes are always nice :p
The movie does a good job of showing how Spiderman is very conflicted: he can't decide whether to focus on his life, or saving others.
I thought the dialogue took a step-down from the first movie. The plot is just too hokey in the way it unfolds. The introduction of Dr. Octavius was so lame, and his character just isn't explained fully. We don't even really know what he was creating.
I thought the FX were better though; Spiderman looked more real flying through the air.
Overall a good movie: The interaction between characters was good, pretty intense stuff despite the shaky dialogue. It just didn't live up to the hype.
