Episode 1: fantastic
Episode 2: slamming on the brakes after the first but still very entertaining.
Episode 3: in true Moffat tradition he drags it into the 21 century..... ..Which i loved for once BUT after 30 minutes i goes south and the Moffat curse strikes again. This guy can write brilliant one off episodes but can not be trusted to carry a show and honestly the less said about the last 10 minutes the better. Lets hope theres no season 2.
