A suspense thriller that deserves all the high ratings and awards it has received. Its scriptwriting is incredible; written for a thoughtful viewer who is able to read the eyes & emotions yet able to understand a plot which includes a bunch of different undertones. This show will not seem as tense or tedious only to viewers who can see beyond a facade.

It's certainly more inclinied towards the psychological part of a thriller e.g heroes unravel a tight tangle of secrets and intrigue through interrogations and reflections type of plot. This is exactly why, I would recommend it to an adult. Specifically a thoughtful viewer who is able to empathize with the heroes even when they do not openly show their suffering.
