Italian director Federico Fellini's mid-term classic "eight and a half" is his peak of maturity. Since then, it began to erode to corruption, partial to sensual indulgence and self-indulgence, such as Fellini's Satini (69) and this film, are excellent works of erosion and decadence. This film reflects the high-class corruption and indulgence after the moral malaise of Christ in the 18th century. Fellini takes advantage of the subject to show the rotting mood of elite literature and art under the crosscurrent of human desire. Lover Casanova is a "sex fighter-quot;, who has won many battles in the love scene" and takes part in sex-making competitions. But this lover suffers from the fact that everyone only attaches importance to his sexual ability and does not attach importance to his ability to help the people and govern the country. And women have no love for him & quot;, when he is too old to lose his sexual charm, he can only regard a robot woman as the lover of his dreams, which is very pathetic.
