Augh I love GoT. I read all the books and have seen all the seasons so far. I'm not too happy with how the 3rd season is going, they keep straying from important book storylines aside from the "Red Wedding".
I love Tyrion, he's my favorite. He's so sassy and adorable. Aside from him I also enjoy Arya, Dany, Sansa, Samwell and Brienne. I kinda like Jaime too. In the books Cersei's chapters are pretty amusing as well. OH AND THE HOUND. Davos is amusing in the show.
I don't really /hate/ anyone, there are some characters in the books that are kinda more boring to read than others is all. In the show I'm not too fond of the Boltons and Freys.
