Who is your favorite movie director and why?

Directors can make or break a movie script. In my opinion, a great director can turn an average script into an above average film. Those directors have to be a stickler for detail and have an amazing grasp of the entire process. I think that the best directors are also good writers/re-writers and love the ART for the sake of the art, especially considering camera work. Is it just my imagination, or are the best directors control freaks instead of wonderful facilitator/managers (getting the most out of the actors and crew)?
