Old Boy
This Korean made film was strange, strange, strange. It tells the story of a man kept prisoner by an unknown for fifteen years - and how he responds when released. It is ultra-violent, dark and in many ways the story of very sad people.
I'd give it a 7 out of 10. Don't think I'd every want to watch it again, but it was an interesting look at the idea of despair and resolution (if given the chance, would you want to end an ugly period of your life immediately, or would you prolong your misery to have complete resolution?).
