all the complains about 'inaccurate portrayal of Germany'...

I'm German and have lived in different cities in Germany (both metros and small cities). There are a lot of reviews here on imdb, where people complain about an inaccurate portrayal of German people. How did they even come up with that idea, when there are only 4 leading German characters in this film - how are those few people supposed to display all of Germans correctly anyhow?

In my opinion those complains are ungrounded, I found that people like the characters in this film exist here and everywhere else. On top of that they were spot on with the love for electronic music and soccer, which, we have to be honest, is true.
