What 's more , in the backstage scene involving Jack and his mother , the presence of blackface subverts the dramatic intent of the scene . When Jack 's mother cries out that her son has to come home to be reconciled with his dying dad , it 's supposed to be heartbreaking , but all I could pay attention to was Jolson 's blackened face and curly wig . Surely that could n't have been the film 's intention , could it?But even out of blackface , Jolson 's performance has n't aged well at all .
According to the above context, answer the following question.
What is the underlying concern at the heart of the narrator 's issue ?


They are concerned about racism .
