Padre Padrone was a film that shocked RTP viewers in the late 1970s, mostly for the visceral way in which it exposed the rude habits of shepherds in the Sardinian highlands, especially in sexual practices with animals.
This film by the Taviani brothers, along with others, such as Ugly, Dirty and Bad, by Scola, are part of the end of Italian neo-realism, that I cannot resist calling hyper-realism, in the sense that it is no longer enough to show the harshness of In reality, we need to look for the most unworthy and grotesque aspects of human condition, in this case the violence, isolation and bestiality of small Sardinian pastoral communities.
Other films had already look at this communities, perhaps even better, such as Bandits of Orgosolo, by Vittorio de Seta, in 1961, emphasizing, in this case, "omerta", the law of silence, distrust, ignorance and extreme attachment to the land, the main source of wealth and power, in these extremely closed rural societies.
I would say that Padre Padrone doesn't add much to Banditi à Orgosolo, other than a certain voyeurism through violence and ignorance.
It's a remarkable film, but I clearly prefer de Seta's Bandits.
