Blade Runner pioneered the cyberpunk style. The film depicts a decadent and depressed scene in Los Angeles after the 2019 nuclear war, nuclear dust floating in the air, ultraviolet rays irrigating the earth unscrupulously, and the human elite has long emigrated to the alien planet, leaving only the old and sick to survive on the earth.
Since humans have begun to gradually enter outer space, Terry has created cyborgs to perform some dangerous tasks instead of humans, and in order to prevent accidents, cyborgs have been set with a life cap, generally 4 years. These cyborgs have undergone version changes and are currently reaching type 6, and unexpectedly, a group of cyborgs have awakened during missions in outer space and begun to rebel against humans, led by Roy. Blade Runner is sent to execute the villain human replicant, but the human hypocritically refers to the execution as retirement.
The opening scene of the film is dark, rainy, crowded streets, modern buildings with ultra-modern technology and colorful neon lights, making the whole tone of the film become very depressing, and a trace of desperate loneliness is revealed under the cold surface. Here, the film's graphics are so powerful and technologically powerful that even thirty years ago, the filming and editing techniques are no less than today's post-special effects.
The picture turns, to the male protagonist Deca eating noodles in the noodle restaurant, and then someone came to arrest him, the reason is that Deca is a blade runner, the movie has begun to leak out here, as a blade runner need to kill the replicants who betrayed mankind, protect human beings, this should be a profession respected by humans, how can it be arrested? There is only one reason, Deca is also not a human, but a replicant, and his mission is to kill other replicants who have betrayed humanity.
When Deca is taken back to the police station to express his reluctance to continue to be a Blade Runner, his former boss says to him, "You're not a cop, just a little person", and the deputy folds a chicken and puts it on the table, which means that Deca is not enough to be a replicant, his task is to execute other rebellious human replicants, and he has no choice.
The heroine, Rachel, is also a replicant, and she asks Deca, have you ever tested yourself on human nature? Humanity tests are specifically designed to test replicants. The shot given to Deca here is very long, so long that people can't help but start to wonder if the male protagonist is really a replicant, and the seeds of doubt are deeply planted.
In the process of arresting Roy, Deca once nearly died, Rachel saved Deca's life at a critical moment, and the two fell in love in loneliness and gratitude. Roy leads the team to Terry, the owner of the Cyborg Manufacturing Company, and learns that the life cap cannot be changed, and Roy acts like a demon in hell and kills Terry in anger.
Roy and Deca finally have a final duel, but Deca is not an opponent, and is chased and killed by Roy, Deca almost falls down the building, Deca grabs the steel plate in his hand, and there is a tall building under his feet. At the critical moment when Deca's life was on the line, Roy reached out to save Deca.
Roy's image has a transformation from a demon to Christ, and at the last moment he completes the arc of the character of growth, he not only lays down the enemy Deca, but also accepts the innate fate of death, and gives himself the highly rotten color of the Virgin, replacing greed and desire with understanding and acceptance. The four-year life limit has arrived, and after Roy's death, a white dove in the camera flies out of a tall building to symbolize Roy's free soul.
At this time, the male protagonist has fallen into painful deep thinking, the replicants are becoming more and more human in the process of being executed, they will be deeply painful for the sacrifice of their teammates, they will finally save the male protagonist as an enemy because of their compassion for life, while human beings are becoming more and more cruel in the process of executing replicants and gradually losing their humanity, which is a very ironic creative method, which dissects the hypocrisy and cruelty of human beings layer by layer and exposes them in front of everyone. What is human nature? Does man have to be human? How innocent the replicants were, created by humans to carry out dangerous missions, only gave them four years of life, and finally did not need replicants, and sent blade runners to execute them. But they also have flesh and blood, and they have their own sense of truth.
After completing the task of executing the replicant, Deca finds Rachel ready to escape with her, and at the door he finds an origami of a unicorn, which is something that has only appeared in his dreams, how did his deputy know about the unicorn? There is only one possibility that Deca is also a replicant, his memories are transplanted, including those in dreams, and the deputy is telling Deca the truth and is kind enough to let Deca and Rachel escape.
At the end of the film, Deca remembers two sentences said by his boss, one is that Rachel can't live, and the other is who can live again? It is implied that the male protagonist cannot live. Deca turns around and takes Rachel to open the door to the future where the ending is known, maybe they will find the possibility of survival, which is the suspense left by the film.
