He's written at length, more than once, about his love for Synecdoche, New York, so it's probably not a big surprise that Roger Ebert has named it the Best Film of the Decade. (And he writes about it at length again.)

"Synecdoche, New York" is the best film of the decade. It intends no less than to evoke the strategies we use to live our lives. After beginning my first viewing in confusion, I began to glimpse its purpose and by the end was eager to see it again, then once again, and I am not finished. Charlie Kaufman understands how I live my life, and I suppose his own, and I suspect most of us. Faced with the bewildering demands of time, space, emotion, morality, lust, greed, hope, dreams, dreads and faiths, we build compartments in our minds. It is a way of seeming sane. (Source)

The Hurt Locker, Monster, Juno and Me and You and Everyone We Know round out his top 5.

How 'bout you folks? Got a top 5 of the decade? Or top 10? And shouldn't December 2010 be the end of the decade...?
