A mate of mine has six kids, and they and their dad all LOVE Doctor Who.
David told me this year that on one memorable occasion, the programme was on one Saturday evening, and the kids were just chatting with each other.
He got up and turned off the TV, and not one of them batted an eyelid.
Very disappointed in The Moff's first series - I always really looked forward to episodes that he'd written in the RTD days.
