Here is the thing... In Nolan's films but especially BB and TDK, however one wants to criticize the fight coordination, it's important for myself to note that for the most part the techniques themselves are totally legit. Facts are the elbows, headbutts and knees used by Bale's Batman/Bruce are some of the most effective things one can do in a fight and when trained to be used at a moments notice can be total fight enders.
Muay Thai/Muay Boran/Krabi Krabong, the various styles of the Filipino Martial Arts, Bando Boxing, and various Silats (real Silat not the wire and SFX assisted stuff we see in THE RAID) use these techniques quite extensively. The problem is that while truly more effective than the theatrical looking spinning kicks and various strikes using the fists or feet, HEK (headbutts, elbows and knees) are not these dynamic looking moves. You couldn't do the things BatFleck does in a real fight, no matter how hard the training is. Real fights are not what we expect them to be after a lifetime of imbibing Hollywood martial arts. The problem is... Those real techniques are not anywhere near as entertaining to watch as other, less real world effective movements. Nolan chose an approach that didn't have a space fro that overly flowery stuff.
