Here are some I just hate:
~ Joel Grey (Cabaret) over James Caan, Robert Duvall AND Al Pacino (all three for The Godfather) for Best Supporting Actor
~ How Green Was My Valley over Citizen Kane and The Maltese Falcon for Best Picture
~ Crash over Brokeback Mountain for Best Picture
~ Art Carney (Harry and Tonto) over Al Pacino (The Godfather Part II) and Jack Nicholson (Chinatown) for Best Actor
Well, I've ranted enough. What are some you can't stand?
