But Netflix's dubs are absolutely TERRIBLE. The voice is out of sync with the lip movement, there is barely any emotion in the tone like in the original audio, the translations are sloppy and don't work for the dialog.
I also grew up with the luxury of having learnt English well enough from young age to a proficiency that I can watch movies in English just as well as in my mother's tongue. This is definitely not true for my family members or even some friends. So when I have a movie on Netflix that is English I chose to watch it in original audio, when it is German (like Dark) I can watch it in original audio, but any other show they produced in Europe I usually give it a try and have to stop watching it because the terrible dub just ruins the experience.
I know there are a lot of people that are fine with subs, but Germans are used to enjoying their movies dubbed. And similarly I heard some American friends who really wanted to watch Dark but were just turned off by the terrible English dub.
So, as far as I can tell, they're very far from creating "common European culture".
