I saw the midnight showing on the 29th and loved it...only one thing I would've changed but it's only a minor detail.
Spoilers below....
I would have changed the order of the ending. I would have put the MJ wedding, MJ-Peter stuff first. Peter goes out as Spidey, does his tour around New York, everything's nice and shiny and it fades to black making everyone think the credits are about to roll on a happy note but they don't. Instead it fades back in to Harry's scene, Norman appears before him, he discovers the Goblin suit and glider. Go to close-up of the Goblin mask, fade to black, roll credits....
