I enjoyed this for its simplicity - very few characters compared to similar wuxia movies, and no extravagant sets or CGI. But the story it tells cleverly leads you through something of a mystery, where the identities of the main characters only become clear to the end. It then emerges as a parable showing that the line between good and evil can be blurry, but at the same time very distinct, depending on the circumstances. The modest production enhanced the message. Also nice to see some less frequent faces.
