For the time, 1979... this was a fun movie to watch. I realize that now it would be hard to watch for most people. I give it 5 stars for being a classic.
If you like Martial Arts, you will like this movie. Ed Parker is a very well respected martial artist.
He began his training in the martial arts at a young age in judo[2] and later boxing. Some time in the 1940s, Ed Parker was first introduced to Kenpo by Frank Chow. Frank Chow introduced Ed Parker to William Chow, who trained Parker while serving in the Coast Guard and attending Brigham Young University. In 1953 he was promoted to the rank of black belt. Parker, seeing that modern times posed new situations that were not addressed in Kempo, adapted the art to make it more easily applicable to the streets of America and called his style, American Kenpo Karate.
