This might as well be first up, since I'm watching season 5 again. This guy.
Fuuuuuuuuuuuuuuuuuuck yooooooooooooooou. You are the worst person in this show, Scott, and this show is full of fucking drug dealers, murderers, and self-destructive psychopaths. He's a liar and a kiss-ass, the reason that the news industry struggles to remain impartial. All he cares about is winning an award, and unfortunately his superiors are of the same mind. He makes me mad every time he comes on screen.
Star Trek: The Next Generation
Deanna Troi is the ship's counselor. She's also an empath. Oh, you don't know what an empath is? No reason you should. Basically, it's a shittier telepath who can only sense people's moods and feelings, but not their thoughts. Bottom line is, she cheapens the show. Oh, we've made contact with an alien race. What's that Deanna? You sense some deceit from their leader? Good. Glad I can expect a "surprise" later. Bitch. There's often a gratuitous pair of boobs thrown into so many shows, and you're Star Trek's.
Gaius Baltar, bane of the human race. Baltar's Wikipedia page describes him as weak, arrogant, and a coward. The only one in the entire universe who cares for him describes him as narcissistic, self-centered, feckless and vain. (The font fucked up here and I don't know how to change it back. Whatever.) Anyway, man this guy. Petulant. I think petulant would be the word I would use to describe him. I keep hoping he's going to die but man, I can just tell he's gonna be a survivor. Sheeeeeeeeeeit.
Huh. I guess I don't really watch that many serious shows that have characters I can actually hate. But...
