The Jews were treated like animals and it was horrible. The Nazi's used the Jews hair, body fat and other stuff that the Nazi's needed. I really didn't like it that the film showed naked bodies but I guess it shows how life was for the Jews.
The documentary was more powerful because it was filmed years after the Holocaust. It really showed how the Jews were treated. It showed the real Jews suffering the way they did when it happened. It showed real heads and real dead bodies.
