What I like about this kind of series is that the story is good by itself but its by no means outstanding. The most important aspect is the storytelling, the presentation, the psychological tour of the characters, the portrayal of different cultures, and family, and relationships, and professions. That's the most impressive thing about this series.
One of the most fascinating things about shows like this is the characters itself are so rich. I've seen very few TV shows that covers extremely sophisticated characters like Matthew on True Detective, and this girl on 'The Night of', and Naz himself. For me, just focusing on the story line for the sole purpose of entertainment is like just focusing on guitar sounds in a piece of music.
This is the reason why I love the first season of True Detective, and this is the same reason why I love this series just after one episode.
