I can say with pride verging on smugness that I've got two very successful shows that assume their audience is very smart.

People don't really have a relationship with great writing or great production or great art direction or great direction. They just sort of admire it.

I stole your childhood and now I’ve led you by the hand to your death. But the worst thing is, I knew. I knew this would happen. This is what always happens. Forget your faith in me. I took you with me because I was vain. Because I wanted to be adored. Look at you. Glorious Pond, the girl who waited for me. I’m not a hero. I really am just a mad man in a box. And it’s time we saw each other as we really are. Amy Williams, it’s time to stop waiting.

I can't see what's wrong about assuming intelligence in your audience and what's bad news about being rewarded for assuming that.

What is immutable about Sherlock Holmes? He favors reason over emotion, but actually underneath that, there is a lot of emotion going on. You can't suddenly make him ordinary because he would hate that. He's not suddenly going to be somebody else.

River Song? Amy Pond? Hardly weak women. It's the exact opposite. You could accuse me of having a fetish for powerful, sexy women who like cheating people. That would be fair.

Like most writers, I write about what has happened to me as that involves the minimum amount of research.
