I came across this show accidentally on Netflix, and wasn't expecting much from it as it was subtitled and appeared to star teenagers. I ended up riveted to the screen, and viewed the entire series over the course of two days. It was a cross between Lost and the Hunger Games, but intellectually better than both. If you are looking for a show that you can't predict from beginning to end, if you like solving tricky puzzles, and/or wonder why odd characters behave the way they do, you'll enjoy this series tremendously. You'll be thinking about it for a long while after you finish watching. There was some violence and limited sex/nudity, but not as much as other Netflix shows. (There was one section in Joanna's story however, that I did not watch.) Recommended for ages 16 and up. Do NOT read any spoilers.
