The selection is terrible - a few BBC series and some weird films. It's really annoying, because Amazon.de has quite a lot of great TV series and films, all dubbed in German, usually quite poorly.
I honestly don't understand how German audiences tolerate it. 90% of the time, it really just sounds like a bunch of actors sitting in a studio, reading lines melodramatically. I seem to remember the LOTR dubs were well done, though. In contrast, I saw the first episode of Game of Thrones at a friend's house and it was godawful. Completely lost the nuance of every performance.
Anyway, other streaming services (Maxdome, Watchever) will give you the original audio track, but their selection is also rather limited.
