Agreed. Venom is one of my fave villians and I love the whole symbiote arc.
Mine too!
I have a great idea for what I would do with symbiote storyline if I had the opportunity to direct a series of Spider-Man films, which is tied into the Green Goblin story and Gwen Stacy's death.
In my concept, after Gwen is killed by Norman Osborn, Peter viciously beats Norman Osborn to a bloody pulp. Before he could finish him off the Green Goblin and deliver a killing blow, Green Goblin sends the glider to impale Spider-Man. He dodges out of the way, and Osborn is impaled by the glider, killing him. Both Spider-Man and the audience are unsure whether he would have killed Osborn if Norman hadn't tried to impale him.
In the next film, Peter feels angry about Gwen's fate, mad at the world for taking the woman he loved when he risks his life to help others. He feels gypped, like all he gets for helping others is crap.
It's at this point that the symbiote enters the equation, brought to Earth on a space shuttle piloted by John Jameson and sent to Dr. Connors's lab for analysis. The symbiote ends up bonding to Peter, and it appeals to his anger and makes him defensive and somewhat impatient. Peter begins viciously assaulting criminals, and it all comes to a head when he beats the film's villain to a pulp. He remembers what he did to Norman Osborn, and then what Uncle Ben might have said about it. He has a crisis of conscience, and leaves the incapacitated villain for the police. He goes off to a church to remove the symbiote with a bell. He throughly rejects the symbiote, and gets it off of him. The rest he brings back to Dr. Connors's lab to destroy it. There, he encounters Eddie Brock, Dr. Connors's lab assistant and Peter's childhood friend (who has been established since the first film in the series), who has been laid off because the loss of the symbiote cost the lab the grant money to pay Eddie's salary. Eddie pleads with Spider-Man to not destroy it, but he proceeds because the symbiote is too dangerous to keep around. Spider-Man sees the symbiote stop moving, so he leaves.
In a following film, we find out that the symbiote was playing opossum, and after Spider-Man left, called to Eddie Brock, and bonded with him to become Venom with the purpose to hunt down and kill Peter Parker. Spider-Man defeats Venom, but not before they tell Harry Osborn the secrets kept from him about who his father and best friend were as Green Goblin and Spider-Man.
Great concept, huh?
