I'm looking for series that creep not in the creepy but in the dark / sad way and are pretty deep. So towards Dark, Black Mirror, Love Death & Robots etc. Have Netflix and Prime Video

Maybe the Society? Is on Netflix. Bunch of high school students are suddenly alone in the city, parents have disappeared, you still don't know exactly. They just have to watch how they are getting along and really sick things happen. Season 2 will come out sometime this year.

I myself watched the first one in a day
