IMNSHO, there is no such thing as a bad martial arts style. There are, however, bad martial artists. The TKD guy was not rechambering his kicks. In addition, he had bad focus and missed on at least three techniques that he should have scored on, as well as relying on single techniques instead of combinations. In no uncertain terms, he was beaten by someone who was better in his chosen martial art than the TKD guy was in his.
