Anton Chigurh from No Country for Old Men is a smartly written smart character. When Chigurh kills a hotel room full of three people he books to room next door so he can examine it, finding which walls he can shoot through, where the light switch is, what sort of cover is there etc. This is a smart thing to do because Chigurh is a smart person who is written by another smart person who understands how smart people think.
Were Sherlock Holmes to kill a hotel room full of three people. He'd enter using a secret door in the hotel that he read about in a book ten years ago. He'd throw peanuts at one guy causing him to go into anaphylactic shock, as he had deduced from a dartboard with a picture of George Washington carver on it pinned to the wall that the man had a severe peanut allergy. The second man would then kill himself just according to plan as Sherlock had earlier deduced that him and the first man were homosexual lovers who couldn't live without eachother due to a faint scent of penis on each man's breath and a slight dilation of their pupils whenever they looked at each other. As for the third man, why Sherlock doesn't kill him at all. The third man removes his sunglasses and wig to reveal he actually WAS Sherlock the entire time. But Sherlock just entered through the Secret door and killed two people, how can there be two of him? The first Sherlock removes his mask to reveal he's actually Moriarty attempting to frame Sherlock for two murders. Sherlock however anticipated this, the two dead men stand up, they're undercover police officers, it was all a ruse. "But Sherlock!" Moriarty cries "That police officer blew his own head off, look at it, there's skull fragments on the wall, how is he fine now? How did you fake that?". Sherlock just winks at the screen, the end.
This is retarded because Sherlock is a smart person written by a stupid person to whom smart people are indistinguishable from wizards.
