Love is hard to do. It's hard to do it right in life. And it's hard to do it right in fiction.
Most fictional love stories fall into one of three piles. The cheerful type, exemplified by rom-coms. The best of this genre is When Harry Met Sally. Then there is the sad kind, e.g. Titanic. Finally, there is the contemplative variety, like Take This Waltz. Since I first saw Waltz years ago, it continues to resonate with me.
