"Daleks have feelings too"

British TV drama is suffering from an overwhelming need to preach, argues Mark Ranevhill in The Guardian.

[The] teaching of moral values is spreading across the TV drama spectrum. The wards of Holby City now live by the same principles, as do the cops at Sun Hill. Even Billie and the Doctor had to learn this time around, in a way that Tom Baker would never have done, that "Daleks have feelings too", and "you can travel in time but you mustn't forget your family". It seems there's nowhere in time or space, or the TV schedule, that can fully escape what they call in American sitcom script meetings "hugs and learning".
