Absolutely loved the experience of watching the first season. It's not the easiest show to get into because it is a show that is rather disorienting (on purpose, I believe). Also, it initially feels like it has LOST-syndrome, where it seems like it's posing a lot of questions that never gets answered just for the sake of being ~mysterious~. But after a few episodes it really starts gelling and it's one of the most captivating shows I've seen in recent years.
The acting from the main family unit (Noomi Rapace, Davina Coleman and James D'Arcy) is excellent and really works to draw you in and engage emotionally with these characters. I am really hoping for a second season, because there is so much potential here.
