I know that Torchwood is supposed to be an "adult" show. I know that it is supposed to be "darker" than Doctor Who. But wow, this show was something else. Something that is not Torchwood.
I've read rumours that RTD is so happy about the ratings for Children of Earth that he wants to make more TW miniseries. Exactly how he plans to go about that with three-fifths of the cast gone, I have no idea.
