Haven't been able to stick with the books so I'm just going off the show.
Favorite characters change season to season but the overall favs have been Bran, Arya, Tyrion, Sam and Gilly, and I still like Dany but her story line is getting kind of boring. Cersei is among the favorites and, though it's my understanding that a lot of people can't stand her, I rather like Sanza in the she's-in-a-shitty-situation-and-I-want-her-to-get-out-of-it way.
Jon has been demoted from the favorites list.

Teenaged X-Files obsession + Bermuda Triangle episode + Self-led school research project = Atheist.
