The background to the film is the question of “Why?”. The director was particularly interested in the question of motivation. In addition to the historical documentation, the film also offers the opportunity to learn something for the present from the discrimination of the victims.

The film was criticized in part for not citing numerous sources and for not carefully researching the backgrounds of interviewees, which meant that they were not always relevant or credible. It also fails to answer the question of how lessons can be learned from the disaster and how such disasters can be avoided in the future.

On the positive side, the film makes viewers aware of their own responsibility and offers great potential for discussion. It is praised that hardly any other film approaches the subject so resolutely and shows that the perpetrators were not monsters, but average men with “completely normal” lives.
