"One Armed Boxer" follows the tried-and-true formula of "teacher murdered, student avenges." Wang Yu plays the main role of Tien Lung, the best student at his kung fu school. A rival school master challenges Lung's master but is defeated. The rival school master, being a sore loser, invites many fighters from around the Asian continent to a tournament. Eventually, this leads to the destruction of Lung's school, the death of his master, and the loss of his right arm. Like in the "One Armed Swordsman", Wang Yu's character is nursed back to health by a young farm girl and her father. You know where the story goes from there.

The highlight of this film is the tournament that features the many different styles of martial arts, including Tibetan monk style, Yoga, Thai boxing, Korean taekwondo, and Japanese karate. However, do not expect much in the ways of quality choreography. Most of these styles are presented as a bunch of different grunts and fancy stretches, which eventually degenerates to the well-known 1970s kung fu style known as "Windmill Fist." Despite this, the fights remain somewhat entertaining because of the creativity infused in them. For example, in the fight against the Yoga Master, the Yoga Master can walk around on his arms and teleport himself from one place to another. It's incredibly cheesy but still manages to come off as "kinda cool" or "funny because it's so bad."

In the end, "One Armed Boxer" is only worth checking out if you are a die hard fan of Wang Yu or you love chop socky "Windmill Fist" movies. If you are expecting a beautifully choreographed and fancifully shot film like something along the lines of a Lau Kar Leung flick, you will be disappointed.
