I've never had a problem with Netflix in Germany. All the productions I've watched so far have had the original language (usually English) available, no burned-in subs. Exception would be transcriptions of on-screen text (like the text messages in Sherlock), but that's because they don't provide separate video tracks for English and German. I'm okay with that.
Of course Netflix doesn't have the new HBO shows - but that's a different issue.
Netflix has by far the best technical characteristics of all subscription services available in Germany (I've tried them all.) Unfortunately its library is laughable.
Oh please, can we stop it already? Yes, it's not as big as the US library. Yes, many TV shows only have the first couple of seasons available with several missing. But there's a lot of content rotation, with plenty of new stuff to watch. I haven't run out yet. You can get an overview what they added recently at http://germany.netflixable.com/
If you're going there to watch something specific, you might have a bad time. If you're going there to discover stuff to watch and have a good time, it's pretty good.
