I can't think of a performer who is better on television than in person.
I think even the characters that are fundamentally evil and wrong, I want people to really love them. I think that's important to writing believable characters. They don't have to be likable but they have to be loved, at least by the author.
I think you can't write with anger. I think it always has to be with a wink. There always has to be an element of hope in what you write. Otherwise you're just getting mad and it's not going to be fun for anybody.
