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.

1 other mistake - chronological order
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
Factual error: Though it's supposed to take place in NYC, when Sandman punches Spider-Man through the back door of the armored truck, as Spider-Man glides on the broken metal door he passes the well known Wyndham Hotel at Playhouse Square, located in downtown Cleveland.
Mary Jane Watson: What's happened to you?
Peter Parker: I don't know. But I have to stop it.
Trivia: While taunting Spider-Man about Mary Jane in the final battle scene, Venom says, "How's that sound, tiger?" He says the same line in the 1990s Spider-Man animated series.
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.
