This thriller is strangely underrated in Brazil, perhaps due to poor disclosure. It has a competent casting, beautiful shooting, writing, and editing. The dog thing reminds Iñarritu's "Amores Perros" (2000), as well the scene at the football stadium (the mythical Pacaembu stadium, in Sao Paulo), seems to be a reference to Campanella's "The Secret in Their Eyes" (2009), two recent important Latin American films. Lazaro Ramos performs a dreadful villain, the first bad guy in his successful career; Babu Santana is perfect as "Santana", a peaceful dogcatcher that plays the drums quite well, in a church. Santana's children are performed very consistently by Thainá Duarte (as "Isaura") and Vini Carvalho (as "João"). Even the dogs deliver a compelling acting! It is not a complex story, but it is beautifully done, and the film is worth seeing.
