This is a very crazy movie. When it ends carelessly or some people outside misunderstand it, it will become a forbidden movie every minute when social events happen due to the misunderstanding of the movie. So far, most people read the film rationally. What the film aims to achieve is not aimless pure violence, but to present the most real appearance of the society to the audience.

If the normal people in the society can respect more, there will be no tragedies like movies (parasites) and (clowns). The clown is obviously not a natural killer, but the result of his outburst after being repressed by the oppressors in the society. He kills people who are arrogant and betray him and make fun of him, but he does not hurt Zhu Ru, who is kind and sincere to him. It is this society that creates clowns. If this society has less selfishness, narcissism and more respect, fewer marginal people like clowns will become social problems. Of course, except for the natural violence and terrorists.

I understand the clown's uncontrollable laughter is not sick. But he had already known all the misfortunes of his childhood in his subconscious. It was his adoptive mother who had been suppressing his character and gradually became as energetic as her. However, when he saw the dark side of human nature such as social discrimination and oppression against him, the clowns in him would laugh, in contrast to Art, who always wanted to pretend to integrate into the society.

There are three kinds of his smiles. One is a strange fake smile that forces him to adapt to the crowd. And that uncontrollable smile is another real clown who has always been suppressed in Art's personality. The other one is a genuine smile in the mental hospital.

If the normal people can respect more, there will be no tragedy like the parasites and clowns in earlier films. The clown is obviously not a natural killer, but the result of his outburst after being repressed by the oppressors in the society. He kills those who are arrogant and betray him and make fun of him, but does not hurt Zhu Ru, who is kind and sincere to him.

It is this society that creates clowns. Social indifference and selfishness can only see people make a fool of themselves. The clown sees this clearly. He sees the fragility of social structure and human nature. He can destroy fear and this structure with a gentle push. As long as the society has more respect, less indifference, more care and less narcissism, the society will have less clowns.

At the end of the film, the clown was very unconvinced when he was worshipped by the violent crowd in the street. If the film ended like this, it would become a film promoting violence. But fortunately, the ending is open, and the ending is to stay in the lunatic asylum. In the conversation between Jackun and the black doctor, Jackun's smile for a few seconds was just a smile, but his heart was full of drama. This is a classic smile, which can be criticized for the weird smile of the last male lead in the classic American film (Psycho). That smile also brought the film to an open ending. You can interpret that it was his idea or that it was all true. This answer is left to the audience for their own interpretation. This is also the mode of a good film, which can enlighten us after watching it.

As the clown said, I always thought my life was a tragedy, but now I find it was a comedy. We should not live for whom, nor should we be led by the society, nor should we repress ourselves too much. If we repress ourselves too much, your life must be a tragedy. We should release the clowns inside. Of course, we should not destroy them with explosive force, but release our true selves. Although we may be teased or excluded by those normal people, we are more comfortable than them, but when you live freely, there will always be a sense of existence in this society.
