Maybe... But I can confirm that Dark is really, really, fucking good. It has a complex story, but (almost) everything is tied up, the bombshells dropping explain some major questions, but give you three more,...
Really, the only problem is that when I say "complex story", I really mean a complex story. You gotta keep your head with it, or else you're hopelessly lost. Best advice I can give is to pause the episode whenever a family tree is shown, and study it in detail. That makes it a lot clearer to understand.
