Biographical or based on true story. I watched half of it, then I went to Wikipedia, rewinded it and watched the ending of the movie. The main problem is that the film is not about an incredible feat or drama, but about some shit, that is, about investing. In life, Roaring Kitty was naturally more cynical and realistic, respectively, and what he was doing was manipulating public opinion through the social network Reddit for his own enrichment, but the financial regulator’s investigative commission could not prove it, especially since Roaring Kitty hired a lawyer who seemed to be skilled.
What the main character did and what he raised his fans to was not some kind of social revenge on Wall Street, at least certainly not the main motive of investors. Yes, private investors have enriched and derailed many Wall Street projects, period. The main character increased his capital a thousand times, from 50 thousand dollars to 50 million dollars. I found Roaring Kitty on YouTube, and he's still active, publicly drinking, for example, Irish dark beer on St. Patrick's Day.
