I'm with soul of Ice on this one. First Spiderman surprised me in how well done it was: good plot, great 1st act (getting/discovering powers), decent dialog, cool action, good villain (especially acting-wise) etc.
All the second one had IMO was good action and an awesome character in JJ Jameson. That guy was born for that roll. But back to the action, it was only good at a couple of points (beginning of first Spidey and Doc Oc fight on top of skyscraper). There's lots of problems I had with it that mad it a bad movie for me, super-hero movie or not:
1.FAR too much top-of-the-lungs screaming. Seriously, it got unbearable.
2.MJ (not well-acted in this one) gets way too pissy for seemingly no reason. So he missed your fucking play because of a perfectly good reason? Why must you act as though it's the end of the world? He's in school, you're not, get over it. This bothered me because it was the root of the whole inner conflict to begin with. So invalid concern for MJ led to an insincere main conflict in the movie.
3.Bad villian choice. Cheesy acting. They never explained why he needed the arm things. "I have invented an infinite and abundant ebergy source (btw, the mini-sun thing was so stupid and insulting to many peoples intelligence), oh yeah, I also made these arms! aren't they wicked cool?" They only used this villian because he fit into two market tested and prooven models of profitable villainy: the ominous stomping of Jurrasic Park, and the jagged, uncomfortable motions of the mechanical arms i.e. The Matrix. Good try guys, but you didn't sell me.
4.Why the hell does spiderman leap out the window when he hears a fuckin police siren? It's NYC!!! If you don't hear at least 4 every hour, something's wrong.
5.There were two or three distinct points in the movie where he would have died. They all involved him falling from great distances onto things and landing on key body parts. Spiderman or not, those falls would kill you (they do in the videogame).
which quite nicely segues into my final point (I had other problems with the movie but ill end the bitchfest there). The Spiderman 2 videogame (not the PC version) is awesome and much better than the movie. I recommend it to any gamer.
