Well, I just finished the series in a go. It's 4 in the morning here. At first, I was scrapping Netflix for something so I started it, planned to close in an hour or so. But it sticks with you right from the starting and by the time you end 1st episode, you just know inside you that you have to watch next. By the time you reach 3-4th the picture gets more clearer and you can't able to stop. Then it gives you some reality of series but the way this series handles itself by the end, oh man!
It has too much timeline travel by which you could get confused in start, but once everything is getting unfolded, it creates both enthusiasm and curiosity inside you. And man, what a cinematography, what a casting, what a way to develop a horror.
Oh yes, horror, you will get some pop-ups (which are good) but I won't count it in horror. Although they showed some supernaturals in this but that's one way or showing the feelings, state, emotions and balance of the characters. Which all the characters embodied perfectly.
In the end, I feel genuinely sorry for you if you are not going to watch it. And, for the others, you are in for a treat.!
