Other mistake: Considering Peter's strength and anger plus power of the symbiote, there is no way that Mary Jane would be completely unscathed after he accidentally hit her.

Directed by: Sam Raimi
Starring: Elizabeth Banks, Kirsten Dunst, James Franco, James Cromwell, Bryce Dallas Howard, Tobey Maguire, Thomas Haden Church, Topher Grace, Rosemary Harris
Plot hole: In this movie Goblin was able to sneak up on Peter. But in the previous movies Peter was able to sense danger from quite a distance away; Green Goblin from a few blocks and the train barricade from over a mile.
Harry: Looks like I came just in time.
Spider-man: Yeah, few seconds ago wouldn't have been so bad either.
Trivia: Stan Lee, the creator of Spider-Man, makes a cameo appearance when Peter Parker is reading about Spider-Man getting the key to the city. He is the man that walks up and talks to him.
Question: This applies to all 3 films. Wouldn't someone eventually see Spiderman coming out of Peter Parker's apartment and put 2 and 2 together? Doesn't this seem just a bit careless on Peter's part?
Chosen answer: Answered in the comics: Peter's Spider-Sense tells him if someone is looking when he's about to enter/exit the apartment as Spider-Man.
