Though I liked the movie on the second viewing I really felt 1 and 2 were better. Here are the things that needed to be done.
1. Cut all the Harry MJ, Peter triangle BS, we have known about this since the first 2. It would easily give us 45 minutes of more interesting things.
2. Cut the Harry and Peter regaining friendship, and having amnesia. Just have him kinda going after Pete through out the film.
3. Have Harry himself fight the bad inside of him, not through the butler, but fighting with his father in the mirror.
4. Cut out a lot of the TV stuff.
5. All the symbiote stuff they had, that made him cocky.
6. cut the MJ drama stuff, it's about Peter Parker, not her. As well take out Peter being so happy. I think this one should of really showed his dark side.
With that you have a lot of room for a masterpiece story. You could of easily developed way more of Flint, and Eddie, make Eddie the reason Peter hates and gets angry to connect the two better. Show how it really ruined Eddies life in more then one way through out time.
The symbiote should of been added earlier on, and not make him cocky, make him angry, filled with revenge, almost making him a monster, so that would truly be the villian within himself to fight. And show him taking it out on petty thugs, him getting mad yelling screaming, turning into Venom technicaly.
Way more of Venom, and have him terrorize more of Pete.
Over all make it much more of a serious movie, they were afraid to get dark, get really dark and serious. We have all the love stuff done in the second one get rid of that, it was excess fat.
I liked the movie, but man, Sam did drop the ball on this one. An entertaining movie, but I think the fans "wanting it to be more comic book" rants got to him, and he made it way too much so.
But I still like the movie, but wish they could re-make it.
