Finished Dark on Netflix. To caveat, I had a stroke on Monday which was between seasons 2 and 3 and my head's not right yet. But with that, I found season 3 to be even more complex than 1 and 2 and to the point I lost interest, though kept going to the end.
Having ADHD doesn't help, but they put too many characters into it to keep track of 3 or 4 of them at different points in time and/or worlds (for each of the characters) at any given point. Took it from a leisurely pleasure to requiring way too much focus. A shame because it had a great premise and the first 2 seasons weren't quite so brain intensive.
