This just a (bad) piece of political propaganda - just ignore it
For those who are unaware of Brazilian politics, you should know that this movie is just a piece of propaganda aiming to transform Luis Ignacio Lula da Silva, today's president of Brazil, into some sort of divinity, martir or something alike, so that he can elect his sucessor or even, as some of his party peers support, try to run for a third term in office. The fact that it was released only a few months before presidential election in Brazil is no coincidence at all.
This movie has no connection whatsoever to reality, as it portraits Lula as someone who only do good things and has good intentions, when of course every human being has a good and a bad side. Well, this movie hides all Lulas bad deeds - like I said, it tries to portrait him as a saint.
This movie shamelessly rewrites history and tries to transform into "historical truth" things that just didn't happened. And, even if its intention was to be a work of fiction (which is not), or a serious cinebiography, it would still be a bad movie: corny story, really bad acting, full of cliches, embarrassing bad dialogues.
So, don't waste your time seeing it. This is a movie tailor ordered by PT (Lula's Brazilian politic party). Basically, it's just bad political propaganda.
