So I watched all but Name of the Doctor and there after, took a break, and my fiancé got into Who. We watched the 2005- series and she was hooked, had to stream Time of the Doctor, and now I'm waiting to see 13 in action. In watching so much of this show, I have to admit, I am seriously disappointed we don't see more Jack Harkness, Ricky, or Martha returns. They all work/ed for Torchwood or UNIT in some form, and I really think they should become regular additions whenever the groups come into play. I understand they don't want to overplay those organizations since they were so intertwined earlier in the show, but really, please? 

Also, was Torchwood actually cancelled? I really fell in love with the gritty, dark sci-fi perspective of the Whoverse and would be surprised if it was considering shows like Sleep Hollow, CSI, Hannibal, and soon to be Constantine are up and around.
