Not sure about this, i'll probably watch S1 through, but kinds of feel like i've seen it before. It strikes me as one of those concept plotline series that lasts a season or two before cancellation and rapidly runs out of ideas.
Whilst i certainly found the first two episodes a bit creepy, its dropped the ball since.
Theres been very little of the ghosts or whatever they are and although the victim bodies are gruesome, theres been very little of them in the last 3 episodes and nothing of them actually attacking bar a brief head into that shed.
Its almost like they used the budget in the 1st few episodes.
