It's kind of funny, when you think about it. Literary writing, or the so called 'quality literature' we read in school that wins Pulitzers and Nobels, almost never have happy endings. They're considered the best of the best of the best (probably because they emulate real life), and yet the best selling books in the world are your run-of-the-mill romances, pop fiction, and everything else. It's an interesting commentary on human nature, IMO. We can admire great writing and those poetic, tragic narratives, but in the end we'd better have closure, and it better make the emotional investment worth it.
