Dark plays with the viewer's mind a lot even if they are paying attention. I mean it leaves you thinking a lot and then the conclusions start to come. On some occasions I had to go back a few minutes to be sure what was going on. However I watched all 3 seasons and thought they were great. A series that hooked me from the beginning to the end.
Sic mundus creatus est!
