As a practitioner of Kyokushin Karate, I found it very interesting to see the roots of my martial art. The fact is that this particular style of Karate has been deemed "The Strongest Karate", known for its pad-less FULL contact sparring: consisting of head kicks, body blows, knees to body and head, and body punches. Just no head punching (or it would be to bloody). this movie is about the very first World Tournament of Kyokushin and it is filled with Hard Core training, cheesy 70's music and crazy spinning back heel kicks to the chin making the opponents jaw resemble a cash resister!, or nasty head kicks blasting opponents on the mat twitching and flexing there toes and fingers like there playing a invisible piano. The story also follows a few American fighters as well as a few from other nations and fighting styles as well. It is as informative as it is entertaining. I had DVR'd it about 3 years ago and had it for most of the time but i changed my cable provider and lost it in transition. If i came across it anywhere I would buy it as fast as I could! if you get the chance to see it take advantage of the rare opportunity. As a MMA fighter and Kyokushin Karate fighter i see both the beauty and the brutality of this GOD HAND KARATE. Osu!!!!
