Kafka, of course
I think there's no need to mention how similar this movie was to Kafka's works. One innocent man by an unknown reason becomes involved with state bureaucryacy that condemns without reason.
But I've seldom seen a Kafka-esque movie that so clearly captured the oppressive and fatalistic atmosphere of Kafka. When the movie ended and I had finished digesting that ending, I just knew I had come out from one of Kafka's parables.
This world is a comedy to those that think, a tragedy to those that feel.
