Comedian David Mitchell has criticised Doctor Who for forgetting it is a kids' show.
The Bafta-winning Peep Show star said it was odd the show was so popular adults.
"My parents never watched Doctor Who - it wouldn't have occurred to them to do so," said Mitchell.
"They might have been fond of it, they might have said, 'Oh yes, I used to watch that as a child'. What they wouldn't go on to say was '...and I still do now.'" He added: "These days, a huge amount of stuff seems to be aimed at children, but with the assumption that adults - and not just parents - will consume it too."
Doctor Who boss Stephen Moffat has said the show is meant to be enjoyed by the whole family.
