Basically I cannot complain about this series, beautifully shot and suspenseful but as others have said it is painfully slow. It could easily have been cut to seven episodes. Too many 'longeurs' like lingering shots of doorways to rooms and how many times do we have to go back to the girl in the cellar, we know she is still there! The director seems to be in love with the 'artistic' quality of the filming. At the beginning the detective's dad seems to have early stage Alzheimers but later seems quite lucid
It may be better in an English sub titled version but I had to watch it in a language subbing with which I am not fluent.
Still very worth the time but I hope if the director gets another series he will be more concise and give more lighting! The latter seems to be the fashion in 21st century directing and in many movies one has to look at complete darkness, at least on TV.
