Ok, first of all, can I say I really love your new ending for the movie? I think it's really inspired and captures the real feel of Spider-Man. All three of the friends with their conflicts resolved and helping and healing one another.
The problem is your epilouge...lots of grammatical errors there, also were you trying to be funny with the "Again"? It felt out of place, I'd have ideally just ended it on the final scene...and where were the end credits? (mind you, I am guilty of doing this with some edits of my own, so that's no big deal)
