Loved Death in Venice but disliked The Dammed which was over the top and agree about The Man Who Loved Women which is my least favorite Truffaut film. Liked all of Tati's films except his last Parade which was kinda boring to me and a sad ending to his great career.
Thought i would mention some of my favorite foreign film directors and the films i did not like that much.
De Sica: A Place for Lovers
Fellini: Satyricon
Kurosawa: Dodes Ka Den
Antonioni: Red Desert
