This is something I really appreciated about Dark (German). They wrote the story as three seasons, it was complete for three seasons, they found and released all three seasons. There won’t be a fourth. It was refreshing.

Where in American shows even if they have some idea where they are going (anti-Lost) they almost never completely shut the door.
