I absolutely loath Joffrey. Which also makes him one of my favourite characters in a way. Written so well, and acted very nicely in the show that I'd love to actually give the actor a slap. That's how much I hate that character
Tyrion, Arya, The Hound, Ygritte, Jon Snow and Victarion Greyjoy yet to be seen in the tv show and doesn't have many POV chapters in the books, he's still absolutely badass though.
