Interesting. I'm sure Germany has a size-able incel problem since I know its birthrates are way down. German women stopped caring about procreation in typical Western style. It will go the way of Japan.
I just watched it. The movie is actually Norwegian, not German at all. It's set in Oslo, and the characters are Norwegian and Swedish. The main character is a fat, lazy, socially awkward porn addict, but a somewhat sympathetic one. The main female character is a typical irresponsible slutty party girl of 20 that's drawn to stupid psycopaths. The two end up sharing an apartment, and their interaction is quite entertaining. There are some disgusting scenes, so brace yourself if you have a soul.
