As someone who has watched every one of the new who episodes with at least one of my children, this is sad news. While all of my children are now adults or very close to it, what about when they have kids? Or just kids in general? Save the non kids stuff for Torchwood.
Doctor Who
A good old fashioned Doctor Who Community
It can't be that scary, his paymasters will want to maximise eyeballs on this. It's likely hype as we've had some scary Doctor Who episodes before (especially in Tom Baker's run - The Brain of Morbius still haunts me. I nearly ran out of the Doctor Who exhibition when I stumbled across the suit) and, unless he starts splashing the claret around, I doubt it's going to require much more than hiding behind the couch (how I dealt with it back in the day).
I suspect it will be still family viewing, just a little dark for some young kids to watch solo maybe
I suspect this is mostly RTD spouting off for publicity's sake and he's just being much more cognizant of the inevitable outrage about people screaming and dying onscreen in an ostensibly family show. After all the show has been through THAT before. He's getting ahead of it. Probably.
