I'm up to episode eight. Don't worry I won't spoil anything.
I think this is alright, but could have been so much better. My main criticism is that they really overuse the horror elements. Something will happen to a character and initially it may scare you, but then they try that exact same tactic again and again within the same episode.
Horror for me works like this. You build the suspense, the feeling that something isn't right and that in turn makes the audience think, "what is the character sensing here that I can't see?". Then you reveal it fairly late in the game. These episodes would work better if they showed a little restraint. Instead the scary part tends to come early on and what follows are several attempts to try and replicate it.
Again I think it's a good enough series, there's one episode with a very unsettling and memorable scene. However as ridiculous as this may sound, it would have been scarier if they stopped trying to scare us so much.
