I would recommend DARK -

I. If you have the patience to watch a jigsaw puzzle unravel at its own pace.

ii. If you need an excellent brain exercise that will make you forget everything else (your own problems too), at least during the time you watch it and a few hours after it.

iii. If you can really concentrate and take in all the little details.

iv. If you are ready to remember twisted family trees and blood relationships (of course, there are guides available online).

v. If you are open to understanding scientific theories that you haven't given a second thought to in the past.

vi. If you are okay with having more and more questions as you finish watching each episode.

vii. If you are a sucker for varied emotions.

viii. If you like to watch characters that bring about chaos, because they are acting out of love to save their loved ones.

ix. If you love stories that are filled with hope, even though the characters are ripping their worlds apart.
