I'm Not Crazy
OK, yeah a little bit, but this struck me too:
Call it overanalyzing, but is it a coincidence that Precious' dark-skinned mother is physically and verbally abusive, her dark-skinned father is a drug addict who rapes her, and the main character herself is a dark-skinned 16-year-old mother of two? Meanwhile, the teacher, social worker and nurse who uplift and bring positivity into her life are all light-skinned.
