Wendezeit

Another german try of romanticising?

The movie underlines "true events behind" right away from the start. Then you get a highly implausible, adventurous and still just moderately thrilling story. IMO pure unrealistic fiction. Espionage in general is a pretty boring and pale task, what you get here is the James Bond alike brewing on television B-level. I guess in hope to make it more appealing. If you can take it as another of Grimm tales, you may enjoy it. If you expect a realistic movie on the background of the "Wende" (Fall of the DDR and german reunion) you likely will be disappointed. German filmmaking often gives plenty of room for a good laugh, as proved here again.
