Another aspect that disappointed me at this movie is that thinking about it, it's a rather poor adaptation of "The Night Gwen Stacy Died," intent wise. 
Think about the original story. Norman finds out Peter's identity and kidnaps Peter's fiance Gwen, who had nothing to do with the situation, and then later drops her off the Brooklyn Bridge when going up against Spider-Man. Peter tries to save her and believes he did when he got his webbing around her but her neck snaps, thus making it Peter's greatest moment of irresponsibility. It was his fault Gwen died. 
Amazing Spider-Man 2 goes out of their way to not make it Peter's fault. Gwen came back to him in the beginning. Also, Peter webbed Gwen to a car to keep her away from the danger! Gwen decided to go to the danger zone (Danger Zone!♪

 herself, and had a freaking police officer drive her! 
After electro is defeated, Harry arrives and assumes that Peter is Spider-Man because Gwen is there, which makes me go "
Really, you finally realized it's Spider-Man?", and take her. One problem I find with this is that Gwen is literally not only the only girl around there, but she is the only person other than Spider-Man around there. Harry would have done that to any person in that situation. It doesn't feel like it was personal because Harry was going insane. 
Now, here is what I feel is the biggest problem with the scene. Before I go on, I will say that the death scene was well done. You definitely feel for Peter when Gwen dies. But the biggest problem is that she died because her head hit the pavement, not because Peter didn't web her head and her neck snapped from the whiplash. Peter wasn't directly responsible for her death like he was in the original story. Surely, if he did she would still be alive, but the movie never explicitly state and non-readers will never make that assumption. 
These changes turn the story, which was a groundbreaking story dealing with Peter's greatest act of irresponsibility and turns it into a a regular (and thin) "I just didn't save the girl in time" story.
