I think its worth me saying at this stage, that Red of Black is not really for ITV viewers its for Syco viewers.
The people who engage with the show, who buy the music, lets call them "Syco viewers"
Red or Black is really an attempt by Simon Cowell to make a TV program for them, using the names already under the Syco group label.
As for Doctor Who, I cant put my finger on why, but I did enjoy the episode, even if there was no big plot arc, no big monsters, just a very watchable and heart wamring self contained episode of Doctor Who, something the show does do very well, but something that has not be done so well this series.
