What are some of the negative aspects of activist art?

Preliminary answer: sometimes the practice of activist art like the kind portrayed in the film is exploitative and can be used to elevate the clout of an artist rather than think of the long term implications of their work and charity.

How does the film add to your perception of life in favelas?
Preliminary answer: I had heard and seen vague documentaries about the poverty, but not seen the human aspect of it. It was intriguing to see people in such crushing poverty attempt their best to be happy and make the best out of the situation. The one scene that really made me sad and showed me how difficult life could be in these favelas was when the boss and his workers cried because he was mugged when trying to come back from the bank with the Picker’s wages and the workers had to get by for a week without money.
