There are a number of Martial Arts-related documentaries and reality TV shows (Human Weapon, Fight Quest, Fight Science, Kill Arman, Deadliest Warrior...) from the last few years, but I have my doubts about the validity of their information content. I'm a long-time martial arts enthusiast but a beginning Martial Artist so it's difficult for me to judge these myself. Are any of these shows particularly good or particularly bad in their discussions of individual martial arts and comparison between arts?
In other words, are there any worth watching for sake of learning something as a martial artist, as opposed to merely being entertained with something that looks like science?
