I've seen that several times today and it keeps making me laugh. Someone commented that he apparently watched the spicy bit but drew the line at handholding.
I can't tell if you're sarcastic or someone really said this, but IwTV series was definitely not light and sugary. It leans quite heavily into the darker themes and violence of the books. The sex scenes aren't super graphic but definitely not nonexistent either, like there's full nudity while they are levitating in one of them, so it's definitely not ambiguous about what's going on.
We already know there's at least partial nudity in M&G from behind the scenes content and Nick's talked about George in terms of being sexual and using that to gain power so I'd expect there'll be sex scenes but probably nothing super graphic. Either way it'll be interesting to see Nick play a character who seduces so many people.

I hope he has good chemistry with his co-stars.
