Do you know series similar to the Mandalorian possibly on Netflix
So if you're looking for Disney series, you'll only find them on Disney +. Disney only produces them for its own streaming service.
No, I'm looking for something in the direction of bounty hunting
Mh, I can't really help you because I don't have Netflix, but there will be something…
Unfortunately there's no (known) science fiction series, because the production is very expensive and entire seasons have to be recorded (unlike a film). I'm afraid you have no other option but to wait for the series to appear in German in spring or to watch it in English.
