The only animated film to make our list, Grave of the Fireflies is - according to Roger Ebert - "an emotional experience so powerful that it forces a rethinking of animation." And he's right: this anti-war film, which sets its focus on two Japanese siblings in the last days of World War Two, will break your heart. An absolute masterpiece.
