n' I'm pretty sure he DOA'd a couple of those rot's.

I mean, I see what you're saying, but on the other hand, besides gadgets and some melee, what else would ya' have him do? Cartwheels and somersaults?

The style of those fight scenes fit Bat's modus operandi, in my humble opinion. Hit mugs hard and fast to incapacitate as many targets as possible and minding not to kill them... you're gonna want to save your flashy Bruce Lee homage for another time, you know? Bracer to the neck, bracer to the throat... shut 'em down with as little effort, movement as possible. That and the element of surprise are what's going to prevail... kung-fu / ninja training 101.
