I wish TW had stopped after COE. The ending with Jack leaving Earth, Gwen, his daughter after the tragedy of sacrificing his grandson to save the entire planet had such a powerful poetry to it. A fantastic ending to a show that had a really shakey start. I recommend TW to all my Who fandom friends, but I tell them avoid MD like the fucking plague. With Torchwood being essentially in limbo now and RTD unsure if the show will ever come back. I like to think COE was RTD signing off on Torchwood as his DW run was also coming to an end at the time.
