The plot of this story is unique to me. Original concept. From introduction of each character they are fully developed with minimal film time. Emotional investment and attachment for Zen starts with Phatchatorn's young Zen and only continues to grow thru the movie. The time and effort, study and research, Yanin puts into this part, gives her complete authenticity and creditability. Body language and manner of verbal iterations are typical autistic behavior. Yanin brings her youth, diminutive size (5ft2in, 90 lb), and the explosive power of her martial arts . The styles of martial arts she portrayed required further research. Tributes to Bruce Lee and Jackie Chan are beautifully choreographed . Yanin's fight scenes display masterful talent, unique attacks, and brutal reality. Prachya Pinkaew is famous for his skill as a director, and with Yanin , he reached new heights. Yanin herself comments on the dangers of the choreography and fight scenes. The cut outs at the end of the movie demonstrate the risks. Coming out of Thailand , this movie is a standout for its inclusiveness of crossdresser/transgender actors. Their parts are seamless and natural, just another character in the scene. The amount of masterful talent of Yanin's physical skills, original concept, directing , choreography, and inclusiveness makes this movie unique, fresh and the best.
