Dancer in the Dark
This is a REALLY good movie...... one problem. Its depressing. And I don't mean make you cry depressing. I mean existential, sleep for 24 hours, apathetic depression. With that said I highly recommend you watch this film immediately after something really, really great happens. That way when you crash you won't fall into the deepest chasm of despair. You'll merely just tumble down a slightly steep hill. Enjoy.
