Overall a very good mystery thriller with importance to people/characters rather than just plot. The casting was very good and the mystery was also well done.
The drama might feel slow for some. Also the editing goes back and forth, and we are left to connect the events to a timeline. But its done well and adds to the mystery. The way the characters were eventually connected was very good.
Could have been tighter with 10 episodes, but I didn't mind the pace.

Definitely worth a try and I would rate it 9/10.
