The American serious drama makes analysis from the perspective of social development and criticizes the inequality in the realistic society based on pursuit of the equality of race,cultural inheritance and social value.The American serious drama can express the voice of the social public,conform to the cognitive psychology of the realistic society by the social public,highlight the specific development status in the American realistic society and express corresponding development viewpoints for the development direction.展开更多
