I stumbled on this by Netflix recommendations and was a little bored at this time, so I thought: Why not?
Overall this film is a light comedy with a solid background. At first I thought this may be part of 'framing', getting the German people to accept the flood of migrants they have experienced over the last years. But there's more to it. I got intrigued after about ten minutes and watched it till the (almost expected) end.
The filming and acting was good, it was good entertainment, but with a slightly belly grim on my side (as a German).
As a comedy this works well, but I found the educational under streams to be better citizens annoying. We Germans don't need that.
I gave a six, though.
