Buh...that whole thing about "a symbol is incorruptible"...no. You remember the Nazis, right? You know that the swastika is an appropriated manji from Buddhist culture that has forevermore been corrupted as a symbol for evil, right?
I mean, the thing with superheroes (and villains) is that the character is not so much the mask as it is the person underneath. I can't say I'm wholly AGAINST Affleck as Batman, but it's not what I'd choose either. There's just this thing about Batman that Val Kilmer, George Clooney, and now Ben Affleck just can't capture.
