He's been pretty wicked in his recent couple of films - given his acting and film-related high calibre, I'm open-minded to his Bruce Wayne/Batman role.
I agree, Affleck deserves a shot, he might just surprise you. And he has the Batman chin, if you look at the cartoons and comics, batman usually has a largish roundish chin :D
He'll do fine. Lest we forget George Clooney did a Batman with nipples on his Bat suit and nineties fueled neon nightmare of a Batman movie. The bar has been set high on Batman suckiness.
