The new Sherlock Holmes show is awesome. Why? Superb casting. Also, the well chosen actors play their characters spot-on. The flat is awesome- a wonderful modern take on the flat a reader imagines while reading the books. Because they have Mycroft as a character. Because they have Sherlock misusing nicotene patches as an modern take on his use of drugs in the books. Because they used the line, "the final problem" in the episode where Sherlock appears to have died. Because they preserved the spirit of the Sherlock Holmes books.
