Come on, Affleck looks exactly like what Bruce Wayne should like like:
He's got the height, build, and facial structure. I always give people a chance, I'm not gonna judge him 2 years before the film even releases, that's just stupid. Everyone did the same thing when they announce Heath Ledger as Joker so why not for once let's just wait and see.
And one things for sure with Affleck, he can 100% pull of the billionaire playboy persona. Baby face? All I see is Bruce Wayne, he looks more like a Bruce Wayne than Bale ever did.
