Article on unlikable characters

Kind of interesting article here on the value of unlikable characters as protagonists.  Chock-full of spoilers for the author's own works and a number of Notable Works besides, so if you're planning to see We Need to Talk About Kevin and don't want the details, don't read this article.

Potentially more useful for those of us working on original 'fic, I suppose, given the constraints of canon characterization.
