When Best Picture locks up each year -- which usually happens sooner than February 2nd so we should count our blessings that this year had more drama! -- the best thing that one can do is find a way to make peace with it. I've followed the Oscars long enough to know that when your absolute favorite in a category wins you should feel rapturous but treat it like its as rare as Brigadoon since you might never see it's like again. The trick to staying sane (not that I've actually mastered this, mind you) is to enjoy the annual awards festivities without caring about the winners so much as the journey to crown them. In its better moments the awards season circus provides plenty of entertainment, delectable star-gazing, and even the occasional conversational or critical insight into what makes particularly movies great or what makes people love particular movies despite their unfortunate lack of greatness.
I've learned to enjoy it when anything in my top ten each year wins something since, in most years, actual favorites are not crowned. It's harder though to enoy your non-favorites winning when they're solidly in the middle of the pack or when a particular forthcoming win defeats something clearly masterful.
