Oh, Tyrion is my favorite character, Tyrion and Ayra - tend to grab at me the most. But I'm also fond of Brienne, Samwell, and Jamie.
Dany, Sansa and Jon Snow have grown on me. I'm on the fence about Bran - those stories are getting repetitive.

I'm not sure Jamie's arc is as perfect as many fans think - there's a few bits that feel a little too neat. But it's not over either and he and Brienne oddly change places, which I found sort of interesting. Also the fact that Martin's maiming of Jamie is so perfectly karmic - it echoes in many ways Bran's injury - in that now Jamie is a cripple, and unable to do the one thing he defined himself by. Bran defined himself with climbing, Jamie with fighting. It's perfect karmic justice and reminds me a little of Spike's chip in how it forces Jamie to rethink his choices and motivations. Also gory beyond belief. These are gory and violent books. The injury changes Jamie's relationships with everyone in his family and is the exact opposite of how Bran is treated. The Lannisters all treat him with disdain. He is isolated by it.
Emasculated in many ways. And it is such an ironic injury.

That's the one thing I like - the karmic twists.

I don't know if I'll make it through the books though - have some of the same issues you do with them.
