Got to agree. The opening titles/soundtrack are awesome and dark but there is just something missing. The first scene is good with the twins but the rest has just been "ok". I'm up to ep 5 so you're ahead.
I thought it was going to be more twisted than it is, kind of a shining meets Amityville thing.
There seems to be gaps between scary bits but the trailer above certainly makes it look a lot better.... Especially that creepy music they have playing.
Still good though
