If you just said that Kung Fu is unrealistic, you need to do your homework, doubleleg. Kazushi "the Gracie Killer" Sakuraba is a wing chun expert, which is, coincidentally, a form of kung fu.
Judge the fighter, not the system. If any one system was better, then all of it's fighters would be too, but that's not the case. The fact of the matter is that the five kung fu experts were not really that good and the muay thai experts were experienced street fighters.
It's a good story, but it's not a basis for saying that Muay Thai is a superior art.
