I read a book. I also watched two previous Harlan Coben's tv series. Based on previous experience I was expecting something similar to Safe or Stranger. And it is not the same! Not at all!
What I found annoying about Safe and Stranger was the fact that all that middle aged average families live in the houses that most people living in UK won't be able to afford. And here we have Poland. And polish scenery. And public sector worker living in the flat like many other polish people!
I also loved summercamp. I remember going to the ones like the one from The Woods myself.
And series is in very slow pace, what helped to create atmosphere and gave time to reflect on the events, however I can imagine that for many people the show will be boring.
