Really great and harrowing end to this 3 part box-set. This really was the first story that properly earned the adult content warning, with some truly horrific scenes. The ending left room for more, which was confirmed in the extras so I'm very interested in how series 2 will go! Lots of possibilities. I do hope they don't shoehorn the Doctor into it as seems to be the norm lately with these ranges that don't center around him
