Ang Lee won best director because he was the best director
Georgre Clooney was the lead in Syriana, so yeah...the best supporting actor thing confuses me, but in terms of what he went through for the movie, and how well he did in the roll, he did deserve it, even if I thought Matt Dillon was better.
Reese Witherspoon won......I got nothing, I agree 100%.
Haven't seen Memiors, so I have no frame of reference, but GN&GL looked damned cool, so I'm going to agree here too.
