While I love Charles Dance as Tywin, I feel they almost made Tywin in the show a little too awesome. It's like I don't want him to die now, but in the books it was extremely satisfying to watch Tyrion kill him, as I feel the books write Tywin as far colder and you simply don't get as much "exposure" to him as the show gives you. I feel like they're going to have to really make us hate him next season.
