兇手還未睡 (Nessun Dorma) (Blu-ray release 2016-12-23) is a Hong Kong thriller. Just before the protagonist gets married, she meets her secret lover, seduces him but is rejected. She leaves, is captured and raped by someone in a mask. Then she is released mysteriously. This occurs soon enough, but there’s nothing thrilling in the rest of the movie. The only thing I personally find noteworthy about this movie is its mentioning of the mathematical Monty Hall problem. Although I would not call this movie a waste of time as some reviewers do, the ending and the screenplay is unsatisfying.
