Spider-Man 4

I know Spider-Man 4 has been canceled because of the bad script but i think of making a better story.

Story
3 years after the events of Spider-Man 3 Peter Parker has still been fighting crime and spending time with his girlfriend Mary Jane Watson. On the news the reporter said there has been a murder named Cletus Cassidy roaming through New York. Peter told Mary Jane he had to stop this murder. Meanwhile Dr. Connors is trying to find a formula to regrow his missing arm. Connors injects himself with the serum that regrows his arm but he gets stressed and turns into the villainous Lizard. At Ravencroft Industries the Scientists discover Spider-Man's DNA and the Venom symbiotes DNA making Carnage. While Spider-Man is chasing Cassidy, Cassidy runs through the police tape that follows along Ravencroft Industries and shoots the scientist studying Carnage. The red symbiote breaks out of the glass and bonds to Cassidy. While Spider-Man crawls into Ravencroft Carnage grabs him. To Be Continued ............
