8. Venom - Spider-Man 3
The Legend: Ever since Spider-Man hit the big screen, Spidey fans put Venom at the top of the list of villains they wanted to see him square off against. Venom is a hulking behemoth that starts off knowing Spideys identity, has all of his powers, cancels out his spider sense, can shape shift, and turn invisible. A couple of these wouldve made Venom an even match for Spider-Man, but all of them? Talk about your overkill.
The Failure: Now dig on this. They cast Topher Grace. Not that hes a bad actor, but hes an epically poor choice for the role. Why would you cast someone who cant even intimidate Ashton Kutcher as your fearsome villain? (Maybe they were thinking Justin Bieber for Carnage in Spider-Man 4!) He gets his powers halfway through the movie, aligns himself with the B-list villain lead, kidnaps MJ, and announces it with a mega phone so that Spider-Man can form a plan of attack and recruit allies. There was nothing at all creative there, generic super villain stuff, through and through.
