Best Drector is the most misunderstood of all the categories during the Oscars. The thought is that if the film is great, so is the directing (and vis-versa). You CAN have a great film with adequate directing. To me, great directing has more to do with how you stage scenes through blocking, pacing, lighting and even cutting. You can have a great actor in a lousy film or a lousy actor in a great film but, it's how he director uses that actor to convey a compelling story.
