The first season of the series hold a approval rate of 80% in the review aggregator
Rotten Tomatoes based on 10 ratings. Cassio Starling, in a criticism for
Folha de S. Paulo, said that "As was clear from both " Elite Squad ", in addition to the box office success, Padilha seeks to provoke social responses, make the public react to anesthesia and automatic slogans .The enormous attention focused on Lava Jato, on the effects of investigations on the present and the immediate future of the country, could not escape the opportunism of Padilha. Therefore, “The Mechanism” developed little by little, almost insidiously, another plot, which justifies after all, the title. By introducing this fundamental question Padilha reaches a dimension, in fact, more political and less police, more daily and less exceptional. " Fábio de Souza Gomes, from Omelete, wrote that the program presents tiring fiction, unnecessary parallel plots, but has outstanding performances. He also commented that "although it doesn't seem a little forced, [Selton] Mello improves a lot throughout the series and manages to lead the story well in the shadows while [Caroline] Abras creates a complex and strong detective who seeks to find the corruption behind the country "He added that" The Mechanism could have been much better than it actually was. " Adolfo Molina, from
Observatório do Cinema, summarizes that "The Mechanism is a failure as a representation of historical facts in Brazil for trying to seek exemption from the bias and failing, and a work of fiction also fails to fall into this trap." Ritter Fan, from Plano Crítico, wrote that "The scripts of the episodes, all written by Elena Soarez, are beyond didactic, with endless repetitions that hit the same monkkey practically every chapter like" fighting cancer does not leave anyone unscathed And things like that. In the field of performances, Selton Mello once again shows that he is one of the best Brazilian actors of his generation, even considering his irritating inability to speak out, his trademark since the beginning that makes understanding what he babble quite complicated. " He praised Enrique Díaz, saying that the performance "immediately resembled that of Robert Knepper as T-Bag, in Prison Break, that is, a rascal and rascal shaped to make us hate him, but at the same time we love him." He concluded by saying that "The Mechanism is a series with potential, but that it is not fully realized." ==Similarities with real life events==
