His acting skill is not even close to being believable as Bruce Wayne and he won't do the role justice. He's not intimidating enough for the role of Batman. Batman is someone that strikes fear in the hearts of men. His portrayal of Daredevil was atrocious and he's not remotely close to an action star or a superhero. Please find someone else and deliver to the fans what they want.

I would like to add that this petition was not meant in any way to harm Ben Affleck or his career. I respect Affleck's work, I just feel he is inappropriate for the role.
I would also like to denounce any petitions on any other sites bearing this title. I am not/nor was I ever affiliated with them. It came to my attention that someone used my title on whitehouse.gov and I do not support that. The U.S. government has more pressing matters to deal with such as the chemical warfare being used in Syria, rather than who was cast as Batman. This is a neutral site which is why I chose it for fans to voice their opinions.
