This show is very original and sometimes extremly scary. The show consists of 13 episodes each series. Each episode tells the story of an even. None of the episode lead on to each other, so anything is posible from week to week. So far i have only watched most of season 2, the show has some very strong and original episodes, and sometimes it has the un-original episode that have been done to death. This series shows lots of promise and i can only hope now that it is being renewed for a third season it will get better and hopefully the story telling will become stronger.
