I understand that Netflix and the corresponding enforcement laws may be a great thing for movie and series makers because they finance local productions. That's good for the local film and TV business but unfortunately they are mostly just copying US productions and "culture."

As a German living in Portugal, I'm in a special situation in that respect and find Netflix offerings lacking a lot anyway. As you'd expect from an American company, they seem to be under the impression that Portugal is part of Spain and constantly advertise Spanish TV series. I don't like them. For some reason there are also Turkish TV series on Netflix, which are pretty much unwatchable crap. German series are also not very good, except for "Dark" which had an interesting aesthetics.

Another thing is that while Netflix series are sometimes okay in quality, "Netflix movies" tend to be absolutely horrible. Some of them seemed to be based on the idea of taking Hollywood movie scripts and putting them through a blender. I've never seen more plot stereotypes than in Netflix movies and stopped watching them entirely. They are essentially just really bad copies of bad Hollywood movies.

I'd rather see old BBC series, rare Hollywood movies and French movies from the 60s and 70s, but in that respect the offerings in Portugal are extremely limited. Netflix seems to optimize for minimizing costs as much as they can while still just about keeping existing subscribers.

In any case, I'd say that the influence of foreign series on the US audience is higher on Netflix than vice versa, because people in the US barely watched foreign series with subtitles before. In Europe, people were used to it already before Netflix.
