First of all, the name of this film has a certain metaphorical meaning. In nature, parasites can only survive if they are attached to other organisms. The parasites in the film represent the poor class, who rely on the help of the rich to survive. The film was presented to people in the form of comedy from the beginning, and the atmosphere was relaxed and pleasant. But with the development of the plot, suspense elements and heavy tone are also injected into it. Let people's mood become ups and downs with the plot of the film, which is also the eye-catching place of the film.
In this film, the lives of the poor and the rich are in sharp contrast. The poor live in the semi-basement, eating fried chicken and drinking beer, while the rich, on the other hand, live a glamorous life, live in spacious and gorgeous villas, drink wine and eat steak. The world in their eyes is completely different from the world view they form, and even the smell they give off can be used to distinguish classes. The poor keep sighing that the rich are easy to cheat, but they don't know that maybe the world in the eyes of the rich should be like this, which shows the sorrow of the poor.
The survival rule of parasites is to keep climbing if they want to live, so they weave a huge net with one lie after another and catch all the rich people at once. At the same time, it also shows the naked reality, and the poor have to face the cruel and cold reality if they want to live. The final ending is jaw-dropping, which also denies the title of the film, proving that he is not a parasite and lives in the sun with dignity.
