Not uniquely corrupt but uniquely violent (before the Ukraine invasion one in eight violent homicides happened in Brazil... not South America, Brazil).

Besides, I don't know great movies that explain the corruption and violence on each metropolis, just this one (and The Wire for Baltimore, which is by the way great television).

I'd recommend also watching the Vice piece on how Brazilian gangs are fueling violence in Paraguay. It's quite jarring to see the slang of street criminals of Rio and SP spoken across the border in what is a war like situation.
