16. Adina Porter as Lettie Mae on True Blood

Tara's (Rutina Wesley) mother, Lettie Mae, is the town of Bon Temps' resident alcholic, not to mention an all-around hot mess. If that's not bad enough, she's also a Bible freak who routinely misuses the good book to bully Tara into thinking that she is the one living a sinful life. Lettie Mae finally gets cleaned up, but then continues to spout useless nonsense and make her daughter feel like shit, while also hypocritically carrying on with the town reverend. Tara had plenty of great reasons to make her leave Bon Temps, but we're sure Lettie Mae was number one.
