I have to say this show has me enticed and gripped in cast, storyline and atmosphere. Brilliantly portrayed from an obviously unsettling incident. Not many series has me gripped, only gravitate towards series that sturs something inside, like Game of Thrones, Breaking bad, Sons of Anarchy, Vikings. I put this is in that catergory, as those shows because it has such a powerful storyline and it grips onto that fascination deep inside. It leaves you so gripped that you long to find out what happens in next episode. Love the atmospheric soundtrack by the way. To cover one point made as a criticism by others..i think its perfect how it is..yes the actors have a strong English accent..but i think you would find if those cast members tried desperately hard to put on a russian accent there would be even thicker criticism. I am going to highly recommend this to family and friends, as they know i will always recommend epic shows. An amazing series i think deserves high praise for brilliance.
