Spiderman 2 is mostly awesome, except for the 5 or 6 scenes that beat you over the head with, 'OMG Peter Parker's real life sucks, even though he is Spider Man'. They should have just had a CGI black cloud continually over his head, raining on him. Would have acheived the same amatuer storytelling technique.
But, the way they handled the Doc Ock scenes were amazing. The fights are done very well also.
I could go into a whole rant on how the celebration on the subway is one of the worst scenes in movie history. Then the whole Bruce Campbell scene, which was completely meaningless and went on 2 minutes too long.
