I was excited to watch this as Vicky McClure has done some great TV and the cast is strong but it didn't live up to my expectations.
I won't post spoilers but the overall story is actually really good however the show takes way too long to get to any kind of reveal.
At first it's unclear whether it's a crime/thriller story or something paranormal. This doesn't add to the suspense but is just annoying as it feels like the show doesn't actually know what it's about. Some of the side storylines are probably supposed to be interesting red herrings but they just feel increasingly pointless as the series goes on.
This could have been an excellent two-parter as there are some decent performances from a solid cast and the core story (when they get to it) is good. As it is, it feels puffy and self-indulgent which is a real shame and a real waste.
