There are many similarities in plot and general structure between the two, but if they are really different, it is probably that the Green Book has some light comedy colors, which makes the audience feel less depressed, while Jiang Ge Liberated is the real depression, which is a constant blow to oppression and resistance.
From this point of view, I still think "Liberated Jiang Ge" is better.
Jiang Ge Liberated is very depressing. The sharpness and profundity of racial issues are clear at a glance, unlike the green paper, which is tender and affectionate, with a little "racial tenderness" looming.
Of course, in addition to these two films, there are many excellent films about racial discrimination. I suggest the following:
1. Escape from Breaking Bad
In fact, the thriller Escape from the Broken City is an out-and-out racist movie. The arrangement of many black perspectives and black psychology is the greatest significance of this film.
The disparity between the social status of whites and blacks and the exaggerated narcissism complex of blacks are all efforts made by this drama to present the most primitive racial problems.
2. Moonlight
Labels of homosexuality and racial discrimination add a lot of color to the moonlight. Three split faces, three twisted feelings, the confusion of teenagers' growth and the conflict of interests of different races, Moonlight is not a special story, but it can even cover you and me.
3. Hidden people
Racial discrimination does exist, but there are also warriors who struggle for racial equality.
Forbearance and persistence, dedication, self-protection and self-struggle, all these qualities are integrated in the three protagonists of The Hidden Man. This movie tells us that the world will definitely become a better place, and racial problems will gradually disappear, as long as you work hard enough and believe enough.
