That's what I basically thought before getting into the dark projection room.
But Precious, a 16 years old overweight girl, is not only that. She lives in a very poor area of NYC, and she's expelled from school. She can barely read, and she's pregnant with her second child; why would she let herself into such a scheme? Because this girl was daily raped by her father, and beaten by her own mother, jealous of the "relationship" between her husband and her daughter.
But when her son is born, Precious decides that she had had enough of this life as a victim. She decides to follow some courses in order to be able to apply for a job and to offer a better life to her two children.
Unfortunately, she has to fight old demons - including her mother, but she is helped by social workers (Mariah Carey in a supporting role), a nurse (Lenny Kravitz!) and a teacher who all believe a better life is possible for the young woman.
Another woman's fight, very moving, revolting in many parts but really well told.
