on that show generally the final fights are against light weight kids. depends on the culture really and how much face they are afraid of losing.....regarding chinese martial arts...you can guess how much face they want to lose.
the shaolin sanshou was the same way, some young sanshou guy to fight in the end.
now try the Kali episode where the final fights were against seasoned marines.
whole different story then.
all in all ive enjoyed the show. certain episodes are better than others, the Mexico boxing episode for example. these guys you see them training and fighting with are real pro mexican boxers. the real deal.
For whoso comes amongst many shall one day find that no one man is by so far the mightiest of all.
