Calling Dr Who a children's show isn't a definition of the audience, it's a definition of the SHOW. In style, pace, tone, sensibility, Dr Who stories are children's stories. Like Harry Potter, Star Wars, The Hobbit, Narnia, Toy Story, The Incredibles and all gorgeous, magical stuff. Does that mean it's not for adults? Don't be daft, adults love children's stories - just look at that list. Some of the most famous creations in the human history! People who grow out of children's stories are people who never understood them in the first place.
Grown-ups are not excluded from this party. Grown-ups are specifically targetted and invited. There are are generally at least two grown-ups per family, and we want the whole of that family round that telly. And we want each of them secretly thinking this programme is really for THEM.
The children's own programme that adults adore. Never been said better. That's what it is. That's what it says on the tin.
