I was fairly disappointed in 1899, after coming from Dark (same creators). Dark was incredibly dense, by comparison. Dark is easily my top show on Netflix, so far.
Concur regarding Dark - it's kind of amazing that Netflix can, when it wishes to, produce "HBO Caliber" content - but so much of the time it's just time-filler drek.
I don't regret a single minute of the time I spent watching Dark 3-4 years ago, nor the time I spent in the office discussing it, or even the time I tried to graph it all (with varying degrees of success)...
