While at first sight it seemed a generic although well intentioned documentary about authoritarian advancement in Brazil (which are fortunately being increasingly produced, with diverse levels of quality or public success), it soon proved to be much better than that. The remarkable outcome is due the excellent interviews with important and well informed researchers and journalists it ensembled. Then, it is a very consistent documentary focusing the strong dishonest bias of the greatest and highly concentrated Brazilian media groups. They are anti-left, anti-people's interests, anti-democracy, and favour their own economic interests and foreign capitalist goals. The film shows, not only with the competent aforementioned analysis but also with several (unbebievable for anyone who lives anywhere else) covers and headlines, how they presented biased information supporting public views against the Workers' Party government and favouring authoritarian right-wing opposition, lawfare, 2016 coup, and the undemocratic government after that. The film also portrays the importance of independent journalism to resist that misinformation and how it has been repressed by the police. The movie correctly connects media unnacceptable behavior with the rise of fascism in Brazil. It has also been hoghlighted gow, despite being the duty of this big media to correct its misdoings in order to recover democracy and avoid further increase in authoritarianism, it did not, as its priority was to protect its own economic interests. This is one of the best documentaries about monopolistic or oligopolistic biased and authoritarian big media in Brazil, together with classic Muito Além do Cidadão Kane, and the tragicomic and innovative Mercado de Notícias, by Jorge Furtado.
