Another 1966 masterpiece (next to Persona and Tanin no Kao) of fractured identities and a self haunted by the weight of the world: war angst, matriarchal authority, absent father, life in the shadow of brother-paragon, repressed desire. De Seta adopts a dizzying (and dazzling) variety of angles from extreme close ups to hugely impressive high-angle shots and delivers a purely formal masterpiece. (Perrin is superb!)
Guilt or deceptive self-guilt? Long entrenched memory or traumatic memory, inadaptability, ultra conservative mother, frustration under temptation. These are some of the themes here. The movie hints but never explains-some of human psychology is like that, here that's exacerbated.
