Complex plots? This director didn’t want them. Expensive, famous stars? Didn’t need them. Glorious sets and costumes? He could take them or leave them. With his choreographer Hsu Hsia, John Lo Mar liked making lean, mean, fighting movies, and fans rejoiced. Here Wu Yuan-chin stars as “the Kid,” a monk whose education in the aptly named “Crazy Lo Han Fist” finds him battling a cruel bandit’s son and befriending an abused prostitute. From then on, it’s one fight after another in another John Lo Mar martial arts marvel.
