Hopefully, any character I play has an anchor in reality. The more fantastical characters, or fantastical worlds that they inhabit are really fun and allow you, in some ways, to tell stories and reveal things about our lives that would be harder to take, in a more realistic setting.

And so, in terms of setting the right tone and finding a way of presenting all of these things, that creates a cohesive whole and doesn't alienate the audience, is tough. That's a challenge. And I think the tone of a lot of shows is discovered through experimentation and actually making it. Eventually, it starts to cohere.
