Ozark for sure. It took the idea of getting out of one problem only to be faced with another to new heights. In The Dark on the CW channel is using the same technique which makes the viewer count the days until the next episode.
I loved "I Am Not Okay With This". And, of course, they cancelled it.
"ELITE", "Dear White People" and "Stranger Things" are my favorites. If I had to pick one, it would have "Stranger Things" since "I am Not Okay With This" is gone.
