But after thinking about it, he might be ok. It will come down to the voice. If he can pull that off, he's good. If he does the Bale dog-barking thing, he's dead in the water.
Just my opinion, YMMV.
One of the things I didn't care for was Bales voice as Batman. At times it was alright when he was yelling at criminals, but most of the time it was annoying. I hope ben just does something simple with his voice.
