I am an independent documentary filmmaker.
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.
