We've been through the age of the TV anti-hero, and seen many a good guy break bad. And while it's fascinating when a supposedly heroic character turns to the dark side, whether it's a brief flirtation or going past the point of no return, it's at least equally as compelling, if not even more so, when a villain goes in the opposite direction.

Sometimes it might work because the actor playing them just has so much charisma it's difficult not to root for them anyway, other times because the work is just so well written, or perfectly fits the plot and takes the show in interesting new directions.
