Movie: Flying over the madhouse. What is the role of the head nurse? What's the metaphorical meaning?

It represents the system, system, social discipline, social order and even the law that ensures the normal operation of social machines.

The organizational structure of human society is interrelated in every era, and group interests must override individual interests, which is determined by human nature. On the one hand, this nature ensures the normal operation of human society, on the other hand, it will certainly stifle individual personality.

The head nurse is a staunch defender of this system in Leap over the Madhouse. She is rigid, stubborn, unsympathetic and hostile to her personality. It can be said that she alluded to some kind of social superstructure, and suppressed the human personality of despising the system, pursuing freedom and yearning for happiness.

In fact, this is the director's exposition of his attitude towards life. He loves human's active thoughts, exuberant vitality and pursuit of freedom. This is a very infectious and good film. I don't think anyone can calm down when I see Mike Murphy explaining baseball loudly to the closed TV, the chief escaping from the madhouse and so on.
