It's a story about something that you and every character in the show/movie want, but you can't have. The ending fills you with a hollow pit of sadness that you can't escape. I'm saying that if you wanna cry then watch either of these. Good things happen but the knowledge of something sad is there and it makes the story more interesting. Knowing that I still watched them... Maybe I'm a masochist? I wouldn't know.
