1. Dana Brody, 'Homeland'
Young Dana Brody falls under the angsty teen category of "they have a terrible home life so it's understandable why they're like this, but at the same time they are so annoying it's simply unforgivable." In fact, Dana Brody is quite possibly the patron saint of that category. Sure, your father is an adulterous terrorist, but really Dana, do you have to be that snarky and immature in every scene?
