Am I the only one here who doesn't really care about the mass of muscle Batman will have?
I mean, as long as he's in shape and knows how to fight and be agile, I don't see a problem.
No ninja ever had the shape of a bodybuilder anyway, or few of them, plus I think this Batman will be good to solve cases and put people in jail without always having to fight.
He always lurks in the shadow in some suspects house, looking for clues, taking the outlaw routes for a good cause. Sure, when an enemies shows up at a crime scene or anywhere he is, he knows how to fight and knock a few of them and then disappear via his gadgets. You know, sometimes it's better to disappear than to try and eliminate all of them while risking dying.
I don't know, it seems this Batman won't be the typical punch-in-the-face and go-to-jail type of hero, more in line with the detective side, he's all about finding clues that helps police (Gordon) catch the bad guys and make them guilty so they go to jail. From time to time catch a serial killer or save a kidnapped person.
This movie may also show how all of his previous actions brings him in this journey, where he slowly creates this new world of freaks in Gotham, Riddler, Penguin and Catwoman being the start.
Just speculation but I really try to interpret it as a way we never seen on big screen before.
