After being welcomed back to España by Franco's government, foot fetishist Buñuel gleefully bit the hand that fed him, turning out a film that was custom made to appal his patrons with scenes like his infamous restaging of the Last Supper. It's an astonishing work; primarily an attack on Christian ethics via the goodness and innocence of the titular novitiate nun whose compassion only leads to abuse and humiliation..
An audacious drama that begins with a weird first half (that partially reveals Bunuels fetishes) then flips and reveals his darkly humorous look at religion. It doesn't completely work but when it does it's interestingly cynical and comfortable with it; it's the type of film where a saved stray dog is just one of many and helping the unfortunate (who even hate a "leper") leads to a disastrous dinner.
There were some memorable sequences in this film (such as the re-enactment of the Last Supper). However, I found this film to be overall lacklustre and sloppily realised. The plot didn't interest me at all either. It really feels like watching a black-and-white telenovela more than a serious arthouse picture.
