The majority of subtitles are just not what's being said at all, for no reason I could discern. It's not like what's being said is strongly at odds with the documentary, it feels like the person writing the subtitles was mostly guessing what's being said. A lot of things are really off too, they avoided the obvious questions about trying to understand the language, and also made the government look unreasonably effective in a way no brazilian would consider remotely likely to happen.
