I was so looking forward to this with Dan Stevens, Mark Lewis Jones and Michael Sheen, sadly I found it tedious and not in the slightest bit dark or horrific. From the calibre of the cast I expected more and when I saw Ed Talfan's name I was really eager to see the production knowing he was linked to it. But there was none of the tension or horror I was expecting which is a real shame when Ed Talfan's TV dramas are excellent.
