First of all, this isn't a documentary. This is a political advertising.
It shows the brazilian left-wing (mostly PT) as a pour innocent victim who was just trying to help the poor people.
It also shows their opponents as bad, religious fanatic people, the classic bad rich white people. This also includes everyone who was not satisfied with the gov, not only the supporters of the opponent party.
They hide and minimize a HUGE amount of information about this party crimes and corruption.
They criticize a lot of things that the others do but hide it when it is they who do it.
An example of this is how they say that the public protests was bad, violent etc. But they don't show the MST and other groups of PT setting roads on fire, threatening civilians and even killing innocent people. Some of them, journalists.
As she shows, she is part of PT supporters, rich and her family owns a company that supports Lula.
The people who watch this without previous knowledge are very badly informed. I'd be ashamed to make it and call it a documentary.
(btw I don't support any of the sides)
