I believe this movie is an accurate depiction of a typical upper middle class or upper class Brazilian household. There is a clear and well defined divide between the haves and the have nots. Val the maid lives in a small room and comes from the impoverished North East of Brazil (just as former President Lula did!). I think the film maker wanted to paint a picture of stark contrasts, somewhat like a film version of Casa-Grande & Senzala by Gilberto Freyre (discussed the various classes and races in Brazil 1933). Although the mother was a pretty overbearing one percenter, I don't think she is unique and could be found anywhere! The father was pretty cool, absolutely nothing phoney about him, all up front. The movie presents the Vestibular University entrance exam system. The system does not distinguish applicants based on societal position. Also the best Universities are free, so we can all learn something from Brazil. Parabéns.
