Must watch 1. Intense pace.
2. Solid background score to go with that intense pace.
3. Natural acting performances from everyone.
4. Season 2 as good as first one, sometimes even better.
5. Solid screenplay and excellent photography.
Definitely very engaging and worth it. Season start can sometimes appears to be a bit slow as the background builds, but then the pace picks up to an extent where you can't stop watching!
This like any other series should not be compared to any other ones. But just so you have an idea of the type of series I tend to like - some of my other favorite series:
Breaking Bad, Better Call Saul, Mirzapur, Khakee, The Family Man, Sacred Games, Your Honor.
