It's Wuxia- what is not to love?

The story involves an evil guy who has learned the ultimate technique- the Iron Armor. He has eliminated all of his weak spots, save for one.

While it is classic, badly-dubbed Wuxia fun (featuring possibly-unlicensed Ennio Morricone music), the whole film is especially great at the end. See this clip to find out why: https://www.youtube.com/watch?v=kxjrxIGnvVk (it gets great at 5 minutes in).

If that scene alone is not enough reason to Riff this film, then nothing is! Balls!
