Very nice.
This movie is hacking + split personality + high IQ crime. The genius of it is that it's not the split personality of the bad street, but. . . No spoilers, you'll know at the end.
The essence of social engineering is to play tricks on a fundamental weakness of human beings: Humans will always only see what they want to see.
In the movie, the code exchange of hackers is visualized as subway + masked man + symbol, which is very interesting.
I learned two cool things, one is the witness protection plan, also known as the Evaporation Secret Order. my country does not have it, but Europe and the United States have it. The witness’s ID number (social number) is directly changed to make it disappear from the world. After doing this, the forces related to the testimony of the witnesses will not be able to seek revenge from the witnesses. Witnesses who have reinvented themselves need only contact the government's Witness Protection Program once a year to be OK.
The second knowledge is Ritalin. This thing is packaged as a "smart medicine" and "focusing on" in China. After a while, high school parents bought it for their children. The drug is very effective because it's a drug (it's inappropriate to say that Ritalin is a drug, strictly speaking, it's a stimulant-type prescription drug). It can excite the central nervous system, improve concentration and learning ability. It is equivalent to other students who are exhausted, groggy, and slow in thinking. You have taken medicine, your physical energy is unlimited, and your brain is running so fast that you can take a pen and dance on the exercise set. ?Because of the problem of drug ingredients, it was later banned on TB, but it is still sold in secret. Ritalin is also very effective for creative workers. For example, when we write articles, we will be exuberant after a few sips of energy, our brains will become active, and our inspiration will continue to flow.
The climax of the film is in the last ten minutes, and the reversal is very interesting.
