The film relies a lot on an old shooting from the "MPB Especial com os Originais do Samba" from TV Cultura, where we get to hear from the lips of our dear Mussum some of the stories that he went through, unfortunately they are quite shallow since that wasn't the goal of said shooting.
The two main issues with this documentary is the poor writing and the film editing. The script has too many unnecessary references that aren't even related to Antônio Carlos, perhaps the writers tried to make something quirk and funny, but they failed miserably. The film editing is just as atrocious, and it seems like, somehow both the editing and writing weren't done in a matter to match.
Besides his upbringing, his modest teenager years, his first steps to the media, followed by the mainstream media and eventual success, there was a huge moment forgotten on this documentary. In 1983, the group almost broke because one of the four members was cashing 50% of their revenue and the other 3 had to share the other 50%, they tried for some months to be separated, but that affected negatively both sides, however it was another important moment on his career, but since said character that got alone 50% of the revenue was a part of the documentary, it seems they purposefully "forgot" to mention that.
Weak documentary about one of the greatest pop figures on Brazilian history, just as important on spreading Brazilian Black culture to the mainstream due to his historic with samba.
