I'm not so crazy about the story (to each's own), but some people might like it. I give it a 9 because this is one of the few martial arts series I've seen with a high-quality production value—especially the directing. The director is an artist. He did the slow motions perfectly, not over-abused and repetitious. The music is top-notch. Very fitting of the moods. The OS is excellent with a Blues undertone. The storytelling is a bit confusing., but due to the production value, you stick with it. This is not a typical roll-out martial arts series where the ending will spoil the entire series after you binge-watch and feel burnt out and disappointed. The length is just right. A build-up of surprising elements. As I mentioned, the director is someone to watch after. I am looking forward to his other works.
