I liked: Türkisch für Anfänger, Dark, Kleo, ans Stromberg. Unfortunately I’d say IMHO if you’re accustomed to US series you won’t find a lot of German ones that stand up to the production values and acting quality. Dark is a notable exception there I think.

Yes, but "Dark" (Netflix) doesn't have a lot of words spoken per hour, as I recall, so perhaps it's not so good for language learning. There's also "Beat" (Amazon) with a somewhat gruesome main storyline.

If you wanted to get linguistically flummoxed there's "Capitani" on Netflix. (A great story, but it's in Luxembourgish!)
