If you are in the mood for a thriller mystery, then I think this is above average, but not spectacular. Admittedly, I am a bit biased because I enjoy, and purposely watch most all of Samantha Morton's work where she gets to stand out. The first episode was a little soft getting into it and I was concerned she was going to have a bit of a vapid character role, but in episode 2 and beyond it gets a bit more engaging and we see a little more expected contribution. I had figured out about 60 percent of the mystery pretty quick, but there is enough concealment to keep some surprises at the end that fits together well and makes a good mini-series binge.
