THE MUSIC WAS HORRIBLE.
Seriously, it completely ruined the movie, it was loud and just plain crap.
Also, not killing Uncle Ben's killer was the biggest no no ever. Killing him is what makes Spider-Man. He has to kill that guy, its the whole point of the responsibility angle.
What are you talking about? He never kills the guy, at least not in the comics. He takes him to the police in both Amazing Fantasy #15 and Ultimate Spider-Man.
