Excellent spy series set in cold-war nuclear-paranoid Germany with some nail-bitingly tense moments and excellent music, lots of it is New Romantics. The decor, the clothes and colours are very accurate and give you a feel for how tawdry life must have been in East Germany. I used to get an insight into that when I first started visiting Hungary in the early 90s, there was still a post-Soviet feel about the country though most of that has disappeared now as Hungary has modernised.
I’m also in love with the theme music, which really has a “German” feel about it: https://www.youtube.com/watch?v=PIlUj9J3quM
