What's a good romantic/drama movie?

Sliding Doors (Gwyneth Paltrow, John Hannah) is a great movie. The ending is a nice twist, which combines both feelings of sadness and joy. I know, weird combination. And as a guy, I am surprised that I like this movie. Just Like Heaven (Reese Witherspoon, Mark Ruffalo) is cute. I'm sure there are more that I can think of, but they are escaping me at the moment. You should really check out Sliding Doors. I think it is a really underrated movie, or just not well known :)
