Thanks to everyone!

Also try Deutschland 83, Deutschland 86 and Deutschland 89, by Anna Winger (I believe).

Goodbye Lenin and The Lives of Others. Great German-speaking films

If you like dark scifi, try Dark (TV series, 2017-2020), with Louis Hofmann and Lisa Vicari. The original language is German (plus I think some German sign language). In the UK you can get it on Netflix. However it has a few disturbing themes. I can tell you more by private message if you like.
