A past-present diptych by Bellocchio that isn’t always tonally executed well, but it remains intriguing as a work about “how we got here” and “where do we go”, as the story of the sinful nun Benedetta and another about an old, vampiric man haunt its similar locale. 

Michel Piccoli and Anouk Aimee deliver Cannes award-winning performances in one of Bellocchio’s finest films, as severe psychological problems afflict a brother and sister who detest but need each other.
