I expected to find this movie interesting, and to enjoy it as kind of a cult-classic of Korean cinema... But I didn't expect to be entranced or moved so deeply. And I certainly didn't expect to still be thinking about it for days and weeks afterwards. The characters are strange, and yet we know them, because we know loneliness. We know what it's like to look into a house and wonder about the lives of its inhabitants. We know what it's like to feel helpless and trapped. And if we don't know what it's like to meet someone who understands us, we want to know, and 3-iron (or "Empty Houses") takes us there. It doesn't shy away from the weird, the violent, or the morally ambiguous, but somehow the main characters' innocence is overwhelming. Weird and wonderful is the best way I can describe the movie. Highly recommended!
