The fight scene was better choreographed than I'd expect, but I'm kind of a martial arts snob. If anything, they showed probably better technique than those men would have had in real life. I doubt they knew how to do the submission hold. Absolutely barbaric that this shit happened.
The ending of TDKR was fine if they were planning on the sequel. That's the only problem. One more problem with TDKR, the fight scenes were terrible. Batman and Bane are both supposed to be martial arts experts. Watching Batman throw wild haymakers was disgusting. If Batman fights me like that, I'd knock him out, yet someone as huge and athletic as Bane.
