My personal understanding is:

Few people think there is anything wrong with the things that we have advertised since childhood to increase cohesion (such as school uniforms and class songs). ), and they also enjoyed it in the movie. Collectivism is very powerful. They can drive away hooligans with dignity and do whatever they want with the collective reputation. Did you notice that at last they cheered for their collective system in the theater? This is the sweetness of this cohesion that makes them dizzy. Some of them are eager to continue this model, even at any cost ... but what if this power is used by careerists?

The Germans made this film, and I personally think it is also a reflection on World War II. We all know that the Germans should be a good people, but they once made the world gloomy. After World War II, some people said that German soldiers were excellent and obeyed orders. They United in the war and marched in an orderly way ... unfortunately, the excellent nation went astray in the hands of Hitler, a madman!

Therefore, there is nothing wrong with collectivism. But if the whole collective is in the wrong direction, or the collective is used by careerists, then the collective will either become a "burning stick" or a "butcher's knife".

Germans love to think. After the war, they made a serious reflection on their own history. China people can also refer to and reflect on this film.
