I always wanted, but it won't happen, this:
Spider-man: Villain: Green Goblin. Origins. Death of Goblin, beginning of Harry's hate of Spider-man.
Spider-man 2 Villain: Doctor Octopus. Peter struggles with his duality. Harry's hate grows to obsession. Peter reveals himself to Mary Jane. (so far so good, right?)
Spider-man 3 Villain: Harry Osborn/Green Goblin II and Scorpion. Peter must fight a brother vs. brother battle. Harry uses his connection and money to hire a "weapon for hire" Project Scorpion to kill the spider. All the while the Green Goblin has returned to terrorize Peter. Peter, believes it to be the return of Norman, as does the audience, until the end when we are all revealed that Harry has taken on the mantel. Harry dies when trying to save Peter from Scorpion. After giving his life for Peter and forgiving him, Spider-man squares off against Scorpion.
Spider-man 4 Villain: Sandman and Electro. Peter meets Eddie Brock. Black Suits origin. Peter dons the Black suit at end of film to fight Electro and Sandman at a construction site (sand at the site for Sandman, and steel girders would conduct electricity for Electro, the perfect advantage for them). Peter proposes to M.J. before he gets the black suit.
Spider-man 5: Villain: The Lizard and Kraven the Hunter. Conners turns into the Lizard. Kraven comes to New York to hunt Spider-man but ends up going after the Lizard. The race is on for Spider-man to save Conners but also stop him. He has the black suit the whole film. Marriage is postponed due to "dark Peter". After defeating Kraven, Spider-man and the Lizard square off at a Church. He defeats him and Conners returns to form. During the fight the bell goes off and Peter learns the symbiote's weakness. After Conners is unconscious, Peter rids himself of the black suit. Eddie Brock is below taking pictures of the fight for the Bugle and the symbiote lands on him. Peter takes Conners to the hospital thinking all is well. Eddie bonds with the Symbiote below at the church and Venom is born as we roll to the credits.
Spider-man 6: Villain: Venom. Peter and Mary Jane marry. Peter and his new bride are taunted by Venom as is the rest of the city of New York.
That was my plan and vision for the basic stories/villains of the 6-film Spider-man franchise, it's rough and not complete sentences, I know. I wanted to spare you guys a lot of details and just give you the meat.
Green Gobin, Doc Ock, Scorpion, Green Goblin II, Sandman, Electro, Kraven, the Lizard and Venom would all appear in major villain roles. Harry would have gotten the conclusion and adaptation he deserved as would Venom. The Lizard would appear, and Scorpion, who I don't think will be on screen would have been great. This is my dream franchise, what did you think?
Yet, based on who's been used in real life, Green Goblin, Ock, Green Goblin, Sandman, and Venom. I'd use Electro.
