Explain the characteristics of different types of movies.

During the period of 1920~ 1930, some artists in Paris art circle were extremely disgusted with the increasing commercialization of films and the shooting of a large number of vulgar and boring films at that time, and tried to make "pure films" to show all the possibilities of film aesthetics as much as possible. This kind of exploration, experiment and research is the avant-garde.

2. New realism.

After the Second World War, some Italian directors put forward the idea of "going to the streets with cameras", looking for events from ordinary people's daily lives and actors from the masses, and made a number of films with strong documentary nature, which reflected the reality of life and the spiritual outlook of the lower classes and exposed a lot of practical problems.

3. New Wave School.

1959 Cannes Film Festival in France witnessed a number of impressive films, characterized by a large number of scenes such as stream of consciousness and flashbacks, which illogically combined many life events with unskilled jumping means, and was called the "new wave" of movies.

4. Political movies.

In the 1970s, the Soviet Union and western filmmakers took major political events as the theme, and made some films that touched on real political issues at home and abroad, serving their own political lines and domestic and foreign policies.

5. documentary style.

This style requires as few assumptions as possible, less conflicts and plots that are emphasized, and it is best to shoot realistically according to the original life.

6. Rational movies.

Eisenstein, a famous Soviet film artist, put forward in the late 1920s that "the purpose of film art is not to vividly express reality but to express concepts", thinking that film is "omnipotent" and even wanted to put Das Kapital on the screen.
