This is the best drama I've seen in a very long time, if not ever. Firstly, Ken Stott is an absolutely fantastic actor, he perfected the part so you really believed he was DCI Red Metcalfe, struggling with all his secrets and dark past. In fact all the actors were excellent in their roles, particularly Neil Dudgeon, Frances Grey and of course, Jamie Draven. The novel in the first place was highly original with an amazingly complex plot, and this was successfully adapted into a high quality, brilliant directed screenplay. To sum up, this was an electrifying piece of ground-breaking drama, every moment communicating mesmerising details about this complex plot and it's highly believable characters. See it if u can, believe me.
