I went to see it at the early matinee before the big get-together with friends tonight, and I absolutely loved it. It was better than the first, though not by much to me, since I really liked the first one as well.
The one thing that the Spidey movies have done better than most superhero movies is find the right balance between action and character development. With these movies you can identify with the characters, but not be bored by all the mundane details of their daily lives and loves.
Also, these movies remember the old axiom that a hero is only as good as his/her villain. If the villains suck (i.e. the last 3 Batman movies) the movie will suck. Despite the (uncalled for, in my opinion) knocks by some fans against the Green Goblin (especially his armor suit) in the first one, he and Doc Ock are memorable, worthy foes for the webhead.
As a long-time (and ongoing) collector of Spider-Man comics, I can fully recommend this movie to anyone who likes the comics, as well as any moviegoer looking for a great summertime movie experience.
Compliments of your friendly neighborhood War Machine!
Sorry. Wrong comicbook.
