Like others have said: watch Dark if you haven't seen it. It's easily the best thing on Netflix for me. Solid acting and character development, great atmosphere throughout all timelines and not that hard to follow despite being in German and a story spanning multiple timelines at once. It's opening theme is quite excellent too:
In similar vibe I can sort of recommend Katla. It's an Icelandic serie where... things happen in a small village trapped near an active volcano. Definitely not as good as Dark, but if you want something similarish it's worth a watch I think.
