The narration way of the story from the first beginning adds another depth to the story.
It shows you scenes from the future then gets to the present to elaborate how we reached that point .
The cast is great , probably you haven't seen anyone of them before , but sure as hell they can act , they are able to deliver the feeling they have so you can interact with them .
Simply , a masterpiece .
P.S : Netflix has always been picky about its series, that''s why it's my favorite network.
