If you're under 30(ish) this won't affect you as much as it should, and will if you view it again 20 years from now. This is about life - the part of life that you can't plan and which will totally sweep you away if it hits you. The characterisation is pure perfection and all three main actors have that wonderful ability to act so well that they can (and will) move you to tears, without saying a single word. The characters beautifully portray the passion and the torment of the sudden unplanned and unexpected - even unwanted attraction that hits them like a slow rolling road roller; remorseless and unstoppable. I wish I could vote 12.
