7) Spider-Man 3
One of the most damning criticisms aimed at Spider-Man 3 is its treatment of Venom. Instead of being the focus of the film, one of the coolest and most beloved Spidey villains ever only properly turns up for about twenty minutes at the end of the movie. And even then he’s in the form of the miscast Topher Grace.
It won’t come as much of a surprise, then, that Venom was not originally meant to be in the film. In fact, director Sam Raimi has gone on record about his distaste for the character. His first choice of secondary villain for the film was the Vulture, with Ben Kingsley in mind to play him. Exec producer Avi Arad, however, was adamant that Venom should make an appearance, due to his widespread popularity.
