Prior viewer's descriptions of the action offered here have been duly attempted and I won't dispute anything I've read. I will just say, you REALLY have to be in the mood for this.
I've been watching Kung Fu movies on TV since the 1970's, and I've seen some pretty wild stuff. But this one dumps a whole kitchen sink of action and effects on you. A lot of it makes no sense and a lot of it looks terrible, but hey, like I said, you have to be in the mood. And as to those cheapy laser beams, just look at American, high-end effects in 1977. Star Wars came out the same year, and the laser effects there were not hugely better than this stuff. Production values as a whole were worlds apart, but the laser beams themselves? Not a big difference.
Thank the Red Dragon, or the deity of your choice, for the El Rey Network. It has "Flying, Five Finger, One Armed, Eight Pole, Shaolin, Exploding Death Touch Thursdays". Wonders like this one are now brought to my TV each week. Not every movie can be a classic like Enter the Dragon, but El Rey shows them all with no prejudice. Actually, thank Robert Rodriguez, for putting his reputation and cash on the line to start that channel. I don't know another network that would show us these treasures.
In a contest for the strangest Kung Fu movie, I'm not sure which one would win, but this movie, and Hong hai er (The Fantastic Magic Baby) are definitely two of the top contenders.
