I suppose it wouldn't really be Game of Thrones if your feelings for a certain character didn't bounce around like a yo-yo. Personally, I hated Jaime Lannister in the first few seasons, but then I realized he isn't such a bad guy. I liked Tywin Lannister for awhile because he would stand up to Joffrey, and then hated him when he did what he did to Tyrion. I even feel a bit sympathetic towards Cersei (even if she is as evil as she ever was).
