Why does Hitchcock show evil but give us confidence in positive energy?

Hitchcock was an American master director in the last century, an Englishman, born in 1899. His films focus on suspense, horror and reasoning, almost all of which are related to death and corpses. Hitchcock was also the first director in American film history to show the theme of death reasoning.

The main theme of the world is sunshine, happiness, happiness and well-being, but each of us knows that there are not only these things in the world, but also the dark side that we always want to avoid. The dark side is not liked by people, but it is real and you can't avoid it if you want to.

Hitchcock chose to face up to the problem and show the dark, selfish and ugly side of human beings to the audience in the form of movies. I think Hitchcock's films show the dark side that people avoid, but the original intention is not only to show darkness, but to compare sunshine and positive energy with darkness. This is Hitchcock's original intention.

Hitchcock's most representative works are Rear Window and North by Northwest. The film "Rear Window" tells the story of a photographer who was injured at home and accidentally saw his neighbor's husband kill his wife through a telescope. After that, the photographer and his girlfriend investigated the murderer together and revealed the true story.

The film is full of suspense, horror, violence, beauty and murder. Although the plot of the film is tense and shows the audience the dark side of human hypocrisy, the answer is given at the end of the film. Suspense is only the performance tool of this film, and the director's real intention is to reflect the relationship between family and gender.

The murdered wife in the back window is a sick woman who is emotionally dependent on her husband. The husband was exhausted and killed his wife in a state of extreme collapse.

Director Hitchcock wants to warn those who are devastated by life through this film, not to compromise with life easily and do irrational things. Because once you do something wrong, the consequences will be punished by law like men in movies.
