No pun intended - the movie is ... well if I called it mad, it probably would still be an understatement! But what to expect from a movie with the devils son ... who is experimenting sexually? I am not kidding ... this is anything but politically correct ... I can not recommend this to anyone who is sensitive ... who may be easily offended and triggered.
This also has a lot of cameos - if you are aware of German celebrities, you may recognize quite a few of them. Claudia Schiffer may have the most memorable of those "roles" I reckon. It is funny, but it also can be distracting .. depending on how you take them ... and if you even care. You may nowadays not even recognize half of the people in this ... like jokes (which the appearances were meant to be), they did not age well ... well will not age well in the future either ... still this can be fun for what it is ... but only if you suspend your disbelief and leave your good taste buds switched off.
