Gripping from ep 1. Quite stressful to watch at times, but have to go back for more to see what happens. First few eps I could only watch one ep a day as it was very unnerving. Acting is superb, especially from the leading character (Alain) who is so sinister yet captivating. Costumes, location so authentic to the time. I'm on ep 7 now so haven't seen how it concludes. So far, one of the best terrestrial shows I have seen.
