I saw Ben's recent talkshow appearance. I have no worry about him showing the angry/brooding side of Batman. He spoke about this side of his personality recently, too. It erupts from him in bursts.
I'm an Affleck fan and I agree that that talk show appearance brought into surface his more passionate side which is definitely a Batman quality. Clearly, it's just a debate regardless of the controversial subject but I'm just afraid for the amount of attention it has gotten and the current events might taint his reputation and reduce the box office numbers for Gone Girl. I really hope people let go of prejudice and avoid doing that. Even for those who might disagree with his views, it shouldn't be turned into hate. He already was unfairly prejudged for his taking of the role of Batman and I don't want to see this turn into another controversy cause I think he just doesn't deserve that kind of treatment, he's just a nice smart guy who works hard and stands up for what he believes IMO.
