If you often watch American TV series, you will not be unfamiliar with all the elements in the film. The story of this serial killer has been over-told in CSI and Criminal Psychology, with more twists and turns and more exciting reasoning. Sherlock Holmes is actually more like a movie about men's friendship. The relationship between Sherlock Holmes and Watson is actually the relationship between House and his best friend Wilson in House, which is a friendship based on banter and ridicule. The loyalty of Watson and Wilson reflects the cunning of Holmes and House. There is another episode in "Doctor House" about House destroying the relationship between Wilson and a woman he likes, but House is more ruthless than Holmes and shows her that he is Wilson's gay boyfriend. It is precisely because of this tolerance and resistance to beatings that this friendship can survive when it really faces the test of life and death. For example, in the explosion on a ship in the film, Grics treated the scene as "gay". Although he had a beard, Jude Law's face with classical lines was still beautiful. As a confident and intelligent person, one of the factors that Holmes cares most about is winning or losing. Holmes' interest in Miss Ajdero comes entirely from the fact that she is the only opponent who has ever defeated him, so that he risks his life to prove himself. Although blackwood was killed by many twists and turns, the person he really needed to overcome was Professor moglia, who was repeatedly mentioned in this film, but did not appear in the end. Anyone familiar with novels should know that this is Sherlock Holmes' most threatening enemy. When Conan Doyle tried to end this series of novels, the final result of the design was that Sherlock Holmes and moriarty fell off the cliff and died together. Of course, due to the strong appeal of readers, the author had to miraculously resurrect Sherlock Holmes, who should have been shattered. A more interesting scene appeared in the "competition" between Holmes and Mary for Watson. Although his wit and ruthlessness can make Mary leave in shame, it can't stop Watson who follows Mary. This kind of loneliness can only be tasted by himself. He can only seek relief from the physical pain of underground boxing. In this emotional mode, the cost of winning or losing is the same.
