Any good examples out there that deal with people in love, and still make a compelling story?
No, because:
all this emphasis on the ‘mythic power of love’ in folk/fairy tales when really, most stories are dealing with early attraction
I don't even want to start ranting on this subject again; it will be like a revival of the duckface thread with its innumerable tangents spiraling off like fractal whorls of irritability and general angry gnome-ness.
So, in short, I think that, no, it would not really be interesting. That sort of thing is for sitcoms. Can you imagine Seinfeld as serious literature? Or even as an entertaining novel? No. The formation of the relationship is the end. A new joint entity is created, and the relationship sort of rides in the background. There's no real goal, so there's nothing to write about. You can only write about other things that happen to people who just happen to be in a relationship. They can be affected by it, but its in the background, like weather.
Unless something revolutionary comes along, like Seinfeld was, I don't see it happening.
