Yeah, the nudity doesn't bother me either, more so my BF. We watch/have watched plenty of other HBO stuff like The Sopranos, The Wire, Boardwalk Empire, The Tudors, etc. It just seems like they use nudity differently in those than they do in this one, if that makes sense?
It's not even really the sex scenes that he has a problem with, because ultimately they factor into the story regardless of how they are depicted. It's that there seems to be more instances of using nudity just because they can rather than for a reason. It's like, ok, you can show boobs, great, we get it, but do we really need those 5 seconds of topless prostitutes in the beginning of a scene, or lingering in the background? I can see his point, it's not really all that crucial to the telling of the story or to set a scene. I think to him, it cheapens it a bit. But he's also become kind of a snob when it comes to TV. I'll watch just about anything and don't really care.
Now I'm really wanting to read the books since you guys keep talking about it!
