It's not something children should watch alone, I'll grant that. But it is and always should be something families can watch together.
I would hate for this to take the same path the Trek franchise did and start adding in a bunch of gratuitous gore, pointless profanity, and alien titties.
Knowing there was new Trek for the first time in ages and then finding out I couldn't comfortably share it with my kids was a big disappointment. I don't want that to happen to Doctor Who.
