I agree with the critics, great characters and performances, but poorly plotted. I had to explain the plot to my mother who got lost in the last couple of episodes. And I had to rewatch an episode to figure it out. It has very convoluted plotting that didn't quite work, which is a problem in the mystery genre. I got very frustrated by the plotting. Apparently it closely follows the books, except for the location, which may have been a mistake. (I wouldn't know I've not read the books? But I've noticed that those who did - had no issues following the plot and loved it. So it may work better for you - if you read the books first? Don't know.)

It does what a lot of mystery shows do - attempt to throw the audience off course with a lots of twists and turns. Except the twists and turns don't make a lot of sense. And various timelines don't quite fit.

I got a bit lost in it. Not helped by the fact that the main mystery is a bit horrific like something out of Criminal Minds. It's a very dark and gritty series, with a lot of graphic violence - some of which is towards women.

But Mathew Goode is excellent in it, and it has some interesting characters who are very compelling. I'd watch S2 for the characters. And I really liked the characters. But whomever is responsible for the plotting, sucks at plotting. (I've been told it's the original writer - so maybe they need to veer away from the source material?)
