This is one of the best movies of all time: ruthless, cold, shocking.
Having a weak spirit means becoming prey to manipulative and dishonest partners, who exploit us at will. Sentimental relationships, if established with the wrong person, become existential traps that kill the soul.
Relationships are complicated: every character in this story tries to explain their actions due to their own emotions, but nothing is rational.
A thread of Arianna links these characters, partly interviewed and in part the protagonists of a narration: the only truth she understands is that life is made of decisions to take, even when they do not want to do so, but are forced by events.
Love is complicated by the whims of the heart, body and mind.
Suffering arises from the conflict between these things being put into play and discovered, in relating themselves to other people.
A touching story that teaches us that mistakes made in our sentimental life have consequences and when this happens everyone would want to have a second chance to go back and be able to do the right thing.
