"Big Short" is adapted from real people and tells the story of the US subprime mortgage crisis in 2008. It turned out that as early as 3 years before the subprime mortgage crisis broke out, a group of ghosts and strangers discovered the clues and predicted the coming of the crisis, so they did vacant loan securities for 3 years, and finally reaped huge profits in this financial crisis.
The protagonists of the film are a group of speculators, and they benefit from the collapse of the country's economy, that is to say, what they make is a national disaster. But you don’t hate them at all when you watch the film, because their insights and research have exposed the greed of Wall Street, the inaction of the government, and the fraud of the entire financial system, all of which were the initiators of the financial crisis.
