I managed to catch the first 3 episodes of the first series. It was amazingly surreal. I saw this advertised in The Times tv guide and they said that the first series is back up on Channel 4OD if anyone ( Like me !) needs a refresher or to catch up.
I worked on series 2. Think it's going to be very special. Marc Munden, the director, is a genius. The first episode takes us back to the beginning of the story. Enjoy. xx
