Those are real scenes.
It is clear that are not acted.
Even if most of the people here are not incapacitated by a kick in balls because of long "training" I can tell you that a guy who is not in BB is down with a good kick.
I remember I was 15 when I receive first kick from a girl that I fought with.
I was on the floor incapable to move. It was a huge shock.
