The idea of making dialogues based in the writings of the conspirators themselves is quite interesting, Joaquim Pedro de Andrade was a skilled director ("Cat skin" is a masterpiece, for example), and the casting assemble great actors. However, the outcome is very boring. Perhaps the poems of those conspirators are too boring, and making a good script based on them was just unfeasible. At least the end is nice, particularly it was the most violent moment in military dictatorship.
