As well, the plot is stupid. [spoilers follow] The hero works for the Qings, so at the very end, out of nowhere, his father declares loyalty to the Mings and poisons himself and his son. It's convoluted throughout.

Don't waste your time. The only thing this film offers is a scene with the development of Mantis style; however the training is very short and unimaginative and the technique is never passed on and hardly even used in subsequent scenes.
