Brienne also made Jamie care for someone for the first time in the show.
I hate Cersei! But the one I really hate is that spoiled brat good for nothing who thinks he rules the world, that stupid little baby tater Joffrey.
Margery is kind of neutral, I'm still waiting to see what's her fate.
I like Aria. I feel sorry for Sansa.
I like Tyrion, Tywin, and I'm still waiting to see Stannis display his full power... so far, he's just talk, but he's got potential to be very powerful.
I also like Sandor Clegane, and Theon is another character I despise. And I liked Cathelyn and Robb, but you know...
I find it interesting what you said about Daenerys, also. I am looking forward to the day she comes and burns Joffrey and Cersei to the ground, but I don't know if that will ever happen. Please expand on that without spoiling me the 4th season, since I'm watching the series but I'm not familiar with the books
