Well, I wasn't expecting Zodiac, my favorite movie from last year, to get any nominations, and it didn't. That aside, my vote for the biggest omission is the lack of a music nomination for There Will Be Blood. At least a third of that movie's power comes from Jonny Greenwood's remarkable score. As Noah pointed out, a greater percentage of the film's impact would be retained if there were music and no dialogue, than if there were dialogue and no music...
