The Oscar history is full of undeserved winners, from movies to directors. Hitchcock, Kubrick and Altman (just to name a few) never got an Oscar for their directing, while Bigelow won it for the fucking awful The Hurt Locker. Oscars are worth for their marketing value, nothing more, if you're a great director you will be remembered in movie books regardless of winning it. In a right world Synecdoche, New York should've sweeped the Oscar in 2009, instead fucking Slumdog Millionaire won.
And I never understood the love for Munich, movie was just ok and my god the sex scene was so bad.
