20. Abby Lee Miller (Dance Moms, Lifetime)
Simply put, Abby Lee Miller is unpleasant to watch. It’s hard to argue that she doesn’t do a good job teaching the kids in her studio how to dance on Dance Moms. She definitely knows what she’s doing there, so you gotta give her props for that. But surely she doesn’t have to be so terrifying when she teaches, right?
It's a problem when you become more known for being the one who yells than for your talent or good qualities. And, let’s be honest here, with all that yelling she does, Miller constantly looks like she would eat you if you got on her bad side. Good reality television doesn't include inducing fear in viewers.
