The best that I can say about the latest entry into the Sherlock Holmes canon of adaptations is that it is better than the previous Sherlock Holmes movie starring Robert Downey Jr. and Jude Law. There is lots of action and great special effects.
Unfortunately, all this nonsense has little to do with Sir Arthur Conan Doyle’s original super sleuth. For the most part, that Holmes solved his criminal cases using clues that he alone was able to spot and interpret. His importance also lay as a forerunner to many of the great modern detectives of literature, such as Miss Marple, Hercule Poirot, and Nero Wolfe.
If you’re looking for cinematic escapism, see Sherlock Holmes. If you’re looking to exercise your “little grey cells” (a la Poirot), read one of Doyle’s books.
