Who's your least favorite main character?

I guess when I say main character I mean characters that have their own chapters.  Man, I dislike Catelyn's chapters.  She's perceptive, I will give her that.  But it's like the only thing I appreciate about her. She's so rotten to Jon.  So rigid.  Like she has a stick up her arse.

I also have a strong dislike for Theon, but we haven't gotten to a Theon chapter yet.  Sooo.. Catelyn.  Ha.
