[on criticism of the violence in 'Game of Thrones'] I think about it in terms of doing a painting. You don't always need a painter to tell you what your interpretation of it is. It's a grown-up show for grown-ups, made by grown-ups. It doesn't necessarily expect you to take any sort of position... I think it would be arrogant of us to say this is what it is supposed to be. It's patronizing for anybody to do that. It's there for what you want to take from it. I think it's as close as you can get to a piece of art for what it is.
