It's alright, it's not one of those dramas that will have you desperate to see the next episode or reach the conclusion, partly because there isn't much of a mystery, the only true mystery is how on Earth can some of the killer's nearest and dearest be so stupid.
It's interesting enough, I like that we see the killer functioning fairly normally with everyday life, and masking their true nature, but incredulity becomes an issue. We are left with lots of loose ends.
The acting is decent, although it is a bit patchy in parts, nice production values.
It is overlong, they could have made it a little more exciting, and had it in six parts, instead they allowed the middle section to drag, the penultimate and opening episode were the best installments, the finale was very disappointing, it doesn't actually progress at all.
A second series isn't needed, it's a decent watch, 6/10.
