I am surprised that so many reviewers didn't like this. It's a well-crafted story, revealing bits of the back story gradually. A bit of a slow burner but I didn't find it too tedious.
The outstanding performance of Erin Doherty persuaded me to give this 8 and not 7. She brilliantly dealt with the switching between daughter and social climber.
One annoying feature of the production was the large number of dark shots. I don't usually comment on such things. Perhaps it was meant to reflect the murkiness of the story.
And one curious thing - perhaps someone could enlighten me. Elliot and Richard are listed on here as appearing as teenage characters in four episodes. I'm sure I didn't fall asleep but I didn't see them, unless it was a momentary appearance in a non-speaking role.
But I'm pleased to have watched it and would recommend it.
