It is one of the most applicable stand up styles period. Very rigid and tough.
If someone is not familiar with it and especially newer or younger MMA fans that are interested in a bit of history should really check it out.
Also try to view it in the context of the time frame prior to an MMA fight on every weekend and MMA schools on every corner.
Tough style with some seriously committed tough tournament fighters and Uchi Deshi, instructors.
As a kid I used to watch "Fighting Black Kings" over and over since there was not a lot of sources to see fights. Sadly I had the narration and dialogue of the show pretty much memorized.
