Bad kids always have different charms, and crime movies are bad kids in genre movies. The charm of bad children is not necessarily bad, let alone eroded, but comes from angularity, complexity and ambiguity. Bad boys can avoid becoming mediocre, walk on the edge and explore the abyss of human nature. From the outside, the scorching sun is a typical bad boy, absconding criminal, homosexual, cruel and violent, with vicious words written on his face. Hand-held photography and fast zoom make the whole movie in a lingering anxiety. In short, there are materials and styles. Three men absconded with sin and led a low-key life with a little girl, until Lao Shui started to make waves again, and they had to face the punishment brought by sin. Judging from the distinction between good and evil, among the three people, only good exists and evil hardly exists. Atonement occupied their lives, and Duan Long, as a policeman, played Iguazhichun and eavesdropped on the landlord's conversation, exposed their past misdeeds. The background of the puzzle line is their evil. Yi, Deng Chao policeman Xin Xiaofeng and taxi driver Yang Zidao continue to encounter some current evils, such as robbery and theft. These evils and the goodness of the three constitute a complex and tense balance. Director Cao Baoping is a master of genre films among academic directors. The original novel "Black Spot" is a crime novel. Cao Baoping moved the story structure out of the original novel, and then slimmed down, trying to release the charm of criminal suspense to the greatest extent. Looking back at the story from the end of the film, we will find that the dark story in this core is more like a dark adult fairy tale. Three guilty people abandoned everything just to make amends. They are like saints and chivalrous men. The unexpected turning point in the closing period aggravated this black fairy tale romance. At the end, Cao Baoping used the suspense trick a little too much. Although reversal can create a sense of surprise, it also needs more reasonable support from the above plot. Once the support is not enough, the film will expose the common problem of genre films: it will become false. The sins of the three men all started with sex, and then sex was completely suppressed like evil and disappeared from their lives. Xin Xiaofeng and Yang Zidao don't have girlfriends. In the original book, Chen Bijue had an affair with the fishing boat owner, but the role of Chen in the movie was severely deleted, and this paragraph naturally disappeared. The grand appearance of the same-sex plot is just Xin Xiaofeng's calculation. In order to fool Yi's eyes, he pretended and forced himself to commit suicide. Xin Xiaofeng became a policeman not to make money but to catch bad guys. Yang Zidao, as an English model, often gives his life to help others, while Chen Bijue, who has a high IQ, plays the fool. Reality and human experience are not enough to explain their behavior. We can only use type experience to understand their spiritual life and the mystery that has lasted for more than two hours. The design of the closing period undoubtedly damaged the charm of some "bad boys" and even turned this twisted story into an artificially touching story of a good boy. The elongated ending makes the aftertaste too long and weakens it. What makes Cao Baoping special is that he likes to learn from genres, but he does not pursue highly stylized audio-visual. He is cold and sharp, but he is also a loyal practitioner of realism. The overall realistic tone provides the film with the credibility that can be squandered, and the regrettable ending does not completely destroy everything that was established before. ?
