Thank You...
If you couldn't detect a distinct style of fighting from Batman, you weren't watching the movie. The fact that Nolan shot most of the scenes ridiculously close is irrelevant, it was blatant Batman had his own fighting style. As Keyser explains, it was quite noticeble all the similar movements and gestures while fighting. The use of the forehead, the knees, the rythm, and most importantly the vicious use of his elbows and forearms.
To me, Batman Begins was hands down the best Batman movie for fight scenes. The blows were vicious, and everything just seemed so damn aggressive. Batman's whole style of using elbow to deliver jaw shattering blows was outstanding. I mean, dude slammed one guy's head into a glass mirror, then jams Crane's face into a concrete wall. No Batman fight scene has been as intense and as animalistic and violent as the scene in Batman Begins. What I connected with was, the distinct impressive state of mind Bruce is when he fights as Batman. He develops this unique style with the Bat-suit on. He has a total disregaurd for his own body, in order to inflict damage on his enemies. The guy is willing to tackle a ninja off a roof and fall a story or two onto another platform and risk his own injury, just in order to completely knock the guy out. It doesn't get anymore bad ass than that.
