Joffrey, Game of Thrones
No. Explanation. Necessary. Simply put, the HBO's current King of the Seven Kingdoms is probably the worst character, adult or child, on TV right now. Or ever. Period.
Carl, The Walking Dead
The little Grimes has killed five other characters, some indirectly (RIP, Dale!), some directly (Shane and Lori, his own mother), so yeah, you could say he's the most polarizing survivor of the AMC hit's zombie apocalypse.
Leo, Smash
Has any character in the history of television been more annoying in so few episodes than Leo, Julia's teen son who actually attempted to redefine the term sullen. How? He was obsessed with his parents adopting a baby from China and was arrested for not smoking weed. He also said things such as, "I don't know what anything is anymore!" (Actual line.) Fortunately, he was soon sent to the Off-Screen University, majoring in never coming back to the show.
Dawn, Buffy the Vampire Slayer
Introduced out-of-frickin'-nowhere in season five as Buffy's younger sister, Dawn, future-klepto, was the Key (walking and talking version of mystical energy). (More like the key to starting an hour-long tirade against her introduction into the cult WB drama. Seriously, how much time do you have?) Like, we're still not over Buffy dying in her place. Still.
Manny, Modern Family
Can you even imagine him as an adult? He'll totally be that pompous guy who is obsessed with international cheeses and whatever the future's version of Downton Abbey is.
Grace, The Good Wife
Alicia and Peter's son, Zach? Golden. Their religion-loving, recently prettified daughter, Grace? The worst. Remember that episode she went missing? That was her best episode. Until she was found.
Dana, Homeland
You know you're really annoying when Saturday Night Live dedicates an entire skit to how annoying you are. Her storylines (Remember when she and her love interest were involved in a hit-and-run? Snooze.) constantly distracted from the good stuff and she managed to make "Dad!" sound like nails on a chalkboard. (Morgan Saylor will no longer be on the Showtime hit when it returns for its fourth season. And the Internet haters claim another victory!)
Declan and Charlotte, Revenge
Yes, they count as kids. And yes, they were the sole weak spot of the ABC sudser's stellar freshman season.
Sydney, Parenthood
Whjle we like her parents, Joel and Julia, their offspring kind of inherited each of their worst traits. She's bossy, a sore loser, likes to throw temper tantrums and has been known to rat out a fellow kid or two in her day on the NBC drama.
Walt, Lost
OK, to be fair, the only reason Walt is on this list is because of Michael's incessant screams of "Walt!" and general lack of doing anything but talking about Walt.
Kira, Orphan Black
We find of feel bad for not loving Kira, Sarah's daughter, but she kind of distracts from the clones, the best part of the show. Plus, we're tired of pretending to like art. Sorry, we're not sorry!
