This weeks Radio Times, once again features a Doctor Who cover and an interview with Steven Moffat, This is what he has to say about the reappearance of the Daleks.
Oh yes, the Daleks. Actually, they aren’t going to make an appearance for a while. What? Yes, we thought it was about time to give them a rest. There’s a problem with the Daleks. How come? I thought they were invincible. They are the most famous of the Doctor’s adversaries and the most frequent, which means they are the most reliably defeatable enemies in the universe. They have been defeated by the Doctor about 400 times. Surely they should just see the Tardis approaching, say, ‘Oh. It’s him again’, and trudge away.
