Steven Moffat talking to the BBC said that US remakes of his shows would not work. I would have to agree as I would not want to see my countrymen make Doctor Who. It would be insane to have two Doctor Who's going on at the same time and I believe it would not work. He also went on a spiel about Sherlock also even though the US Elementary is an entirely different show all together. Even though I agree on him about Doctor Who here is what the pompous one had to say about both shows.
"You couldn't have more than one Doctor Who in the world. It would just be dreadful. We don't own Sherlock Holmes, we don't even own the idea of updating Sherlock Holmes.That's been done before - several times actually. So there's no action to be taken. There are no shows from America that are big hits in Britain. They're all minor hits. Your mates may talk about them but no-one's watching them. They're getting squashed by the locally-made shows. Always."
