According to historical records, Renault was very angry when he saw Lumiere's film screening on the streets of Paris. There may be two main reasons:
1. Poor film quality: Lumiere brothers are pioneers in early film production. Their films are characterized by realism and recording life scenes. But Renault thinks these films are too simple and ordinary, lacking artistry and technical content. He wants to see more complicated and elaborate movies, but he thinks the quality of movies shown on the street can't meet his expectations.
2. Inappropriate screening environment: Renault believes that films should be held in places specially built for film screening, rather than being displayed on the street at will. He believes that such a screening environment does not respect the art of movies and will also affect the audience's viewing experience. He may think that this kind of random screening reduces the value of the film and makes him disappointed with its prospects.
In a word, Renault has high pursuit and expectation for movies. When he sees Lumiere's movies being shown in the street, he may be angry because of his dissatisfaction with the film quality and the environment.
