I loved Persepolis so much! It's a great minimalist foreign animated film about a free-thinking girls' life growing up in Iran under the fundamentalism of the Islamic Revolution. It's so funny and moving, and the animation is really beautiful in its' stark black and white images of this flavorless country. WAY better than Ratatouille!
UPDATE: Ratatouille won. I figured it would, and it was a good movie, but I was really hoping for Persepolis.
