So by now I'm sure you've heard Affleck will be Batman in the upcoming Superman/Batman film. So my two cents is, I'm fine with this choice. Sure there are a few people I might have picked before him, but I think he'll do just fine. I might be in the minority but I thought he was a fine Daredevil. The only real problem with Daredevil I thought was Jennifer Garner as Elektra.
So to all the naysayers, give the guy a chance, I think he'll do just fine.
