I love this category- especially when someone unexpected and deserving wins it (see Roman Polanski for The Pianist). This year is a little unusual and, I think, a little predictable as the category is identical to Best Picture:
Danny Boyle. He has a wonderful vision and of these nominees he deserves it the most.
What Should Win:
Darren Aronofsky. Moreso than being snubbed for Best Picture, I think The Wrestler had the best direction I've seen this year. I really wish the Academy had done right by Aronofsky by at least giving him a nomination.
