P.S. Don't judge this series by 1st 3 episodes, otherwise you will drop it.
The base story is just amazing, it's one of the best of the ones I have watched in months ad I have watched over 100.
The series is underappreciated but I think I understand the reason why, which I will cover it in some points below.

Scope of Improvement and where it went wrong
* The story was confusing, the structure of scenes/script seemed incorrect.
* Slow Paced series, it could have been wrapped in 8 episodes easily.
* Some of the side stories were unnecessary just increased the confusion and made us lose focus in the main story.
* The timeline, 10 years duration just doesn't match with how the series was presented.
