Truffaut showed his accurate and very subtle grasp of human emotions, especially love relationships. He was very aware of the impulse that humans often cross the barriers to find new feelings, as well as the consequences and pain caused by this impulse. Subtle display and discussion.
The film uses a kind of cold humor, blending the observation of life details into a cold and smooth director's technique, and has a subtle depiction of the emotions of people who are gradually indifferent in the city, especially between husbands and wives, men and men who are very different in age. The estrangement and hatred caused by the lack of communication between the mistresses and the inability to understand each other is deeply expressed in the film, and the development of the fate of the characters created by a series of seemingly inadvertent coincidences actually shows that the director’s heart is unable to fail. The helplessness and compromise felt in controlling fate. The control of the atmosphere is full of tension and suspense, and still has a Hitchcock-style mockery, expressing the author's tribute to it.
