Their library has all but disappeared compared to when I joined a few years ago. It looks like they have lots of content still, but my only language is English, and when you start looking at things you find over half the shows in other languages, most with english subtitles. Tried watching a few, very hard to follow most shows cant read and watch at same time. This is clearly intentional and there is no way to search for shows in your language. Makes the service marginal at best. In past they had a huge library of English TV series and movies, most of which are gone now. I was watching a few series only to have them be deleted while I was part way through. I'd try Flixtor.tv (I have no affiliation)which has more english language content and has a free option with no ads.
2 stars instead of 1 because Netflix does have some English content, and some Netflix made content (although most of the "Netflix Original" is non English.) If they did have a way to search for shows actually in the language you speak most of the content would disappear from the search screens. Very sad trend.
