The Battle Of Algiers just barely edging out 8 1/2.
I love Amelie more than probably most here. I found it to be unique and memorable and full of charm. It's certainly a hell of a lot better than almost all the romantic comedies that came out in the past decade.
Playtime I like a lot, but prefer Mon Oncle and Mr. Hulot's holiday.
Brazil has great things in it, but is far from perfect, like most of Gilliam's films.
