It is a piece of art. Every episode gives us enough, but not too much and always made me watch further. All 3 seasons are great. 1st season has it's vibe where you don't know much ambut you want to know what's going on so you keep watching. At season 2, oh boy, it's getting even darker and better. And in S3 the last episodes were just wow.. I loved how there were 2-3 groups of characters where they all are after the same thing, but all know different things about it.

Cons - S3 where all characters went all boyfriend girlfriend stuff, it was not neccessary.
