Grave of the Fireflies is an emotional experience so powerful that it forces a rethinking of animation... It belongs on any list of the greatest war films ever made.
Roger EbertIn the vast majority of movies, everything is done for the audience. We are cued to laugh or cry, be frightened or relieved; Hitchcock called the movies a machine for causing emotions in the audience. Bresson (and Ozu) take a different approach. They regard, and ask us to regard along with them, and to arrive at conclusions about their characters that are our own. This is the cinema of empathy.
