This film is in the collage style, pioneered by some other Brazilian films about significant musical composers / performers. In that respect the film is well made, with techically adept intercutting between different Titas performances of the same songs, during different phases of their career. Initially, the film shows the band's early development, when they were fast becoming popular, with lively songs and presentation, via clips from old TV shows / etc, of miscellanous quality but OK within this verite documentary style. And the English subtitles enable a non Portugese speaker to follow the gist. Later, coming into conflict with Brazilian authorities ( military dictatorship), the band's attitudes and material become darker, reflecting the political and social climate in the country. But, the film is directed by a longtime member of the band, who had lots of off-stage video footage, from years of taking a VHS video camera along on the road. The film's structural weakness is to include too much of this stuff, tedious in content as well as poor quality, mostly straight from the Rock-Doc Book of Cliches. Mumbled conversations on dark tour buses, meaningless antics at parties and in hotel rooms - these add nothing to the film, instead they subtract from it, by boring the viewer. Millions of Brazilians love this band and flocked to see the film, but otherwise, it's unlikely to make you a fan
