What are the respective concepts of main melody movies and mainstream movies? What is the difference?

Theme film: a film that promotes national ideology under the guidance of the government. "Everything that preaches truth, goodness and beauty is a theme movie" (I remember it seems that Grandpa Xiaoping said it)

Mainly includes:

1. Major historical themes: Focus on China's revolutionary struggle history, victory history and biographies of leaders, such as Armageddon series, founding ceremony, fighting in the south and fighting in the north, Zhou Enlai, etc.

2. Realistic theme: the moral and ethical films of heroes and civilians, such as Zheng Peimin, Ren Changxia, The Day of Leaving Lei Feng.

Now more is focused on the revolutionary war, outstanding communist party member * * * and other topics.

The mainstream form of China's films is actually composed of two kinds of films: one is a political, historical and ethical film that promotes the main theme and national ideology, that is, the main theme film; The other is a commercial entertainment film with comedy and tragicomedy as the mainstay, supplemented by martial arts and detective types.

The difference is that the main melody movie is included in the mainstream movie, which belongs to the mainstream movie.

Nowadays, many movies are not entirely theme movies, but only commercial movies with theme colors. This is a transformation of the theme film after the film market.
