Lost

Damon Lindelof made both and has talked at length about the second as his answer to the criticism of the first. Lost trained an audience to expect that a mystery would be explained and then could not deliver; The Leftovers opens by telling you the central event will never be explained, and makes that refusal the subject. The machinery carries over intact, an ensemble revealed through single-character episodes and a community organised around an inexplicable event, with the promise removed on purpose.

Baran bo Odar and Jantje Friese have talked about Lost as the show that made this kind of series possible, and Dark is built out of its machinery: an ensemble whose secrets are revealed by shuffling time, an episode that belongs to one character's backstory, a hatch in the ground, and a mythology released in pieces. The difference is the one they have emphasised, that they wrote the ending first, which is the criticism Lost attracted answered in advance.
