Episode 6 was Sansa's rape. By far the worst received episode in the show's history.
Man, yeah. I really didn't like that at the time - in fact I think I didn't watch the rest of the season until quite a bit later, when I had kind of forgotten it happened and how much it annoyed me. I'm not a person who applies morality to what should and shouldn't be shown very often, but that event, for reasons I can't remember right now, really was over the line to me in terms of exploitation and just...I dunno, nihilism.
They're lucky that they pretty much deflected that hit and went on to continue to grow their success, because I remember a lot of shit storming around about that at the time.
