Dark, the German Netflix show.
Moody, sci-fi/fantasy about time travel and the end of the world. Someone invents a time machine that can travel between 33 years into the past or future. So, it takes place in 1921, 1954, 1987, 2020, and 2053. I'm pretty sure at least one character is his own grandfather and there's a book about time travel that wrote itself, which they actually address. Its dark and moody and darned good but time travel is pretty hard to pull of in fiction and it I'm afraid it will end up like Lost.
