I saw the sneak preview Monday, and I have to agree with the reviewer, that this movie was definitely better than the first one.
I own Spidey 1 on DVD and have watched it a number of times. Up until Spidey 2, it was my favorite comic book movie.
After seeing Spiderman 2, I am now very excited about the potential of this franchise. There are so many cameos and reasons for some people to hold a grudge against Peter/Spiderman, that by the end of the movie, you are left wondering which villain(s) will be in the third one. I am REALLY hoping to see Venom or at least Carnage in the third one, but I won't get my hopes up.
One more thing I really liked about this movie - everyone did such a great job making you care about Peter/Spidey as a human. Possibly the most touching scene in the entire movie is the end of the train scene. You'll know what I am talking about if you've seen the newest commercials or the movie.
