This started well. 2-3 episodes in I was hooked and then it was a downward spiral from there. This could have been excellent, but sadly it wasn't. I blame the writers, not the acting. There were parts that had the potential to grow into something really chilling with an amazing twist, and I think that was the aim, but, the twist was the kind that makes you roll your eyes to the ceiling. I sat with my arms folded thinking 'oh god, come on, really?' It could have been so much better. I've been giving BBC and ITVX some time recently and frankly, I feel much better about my Netflix subscription.
