The start of this psychological mystery thriller draws the viewer in and wants you to watch more and more. It is quite disturbing and well acted out by the main cast. They really portrayed each character pain and the suffering they must have endured at the hands of their kidnapper. Unfortunately the story line does lack more depth to provide you with a further understanding of character background. In particular more about the killer themselves and their motive. At the end of this series I really thought this would be the case. Instead I was left with lots of questions. Such as: Why did he kill the women. What was the motive? Why sid he keep the children. What about the boy and his father? How did she escape without tripping landmines? How did the killer fit cameras in everyone's houses? How did the girl walk out of a house surrounded by paparazzi? Why did the girl that was so brainwashed think nothing when he was killed? What was the purpose o the cop having an affair with lenas mother? Why were the police so enept? Shall I go on.....Remake the last episode. The rating will improve.
