The last 15 minutes or so ruined the whole movie (Spoiler)
I mean, this young girl has just been raped by the guy she (naively, but hey, she's supposed to be 14) thought loved her and is completely traumatized by what happened and probably even more by the coldhearted reaction of her mother. She even wants to kill her rapist only to realize that her mother protects him and would rather die herself then live without her pimp(!!). Then she just walks away, drives (she is 14!!) to her basketball match, wins it basically alone setting a new record, picks up her sisters and sings along happily with them. Oh yeah, that's all sooo believable. What is she supposed to be, a super hero? A believable ending would have been that her team loses because she blows the final shot, her coach is mad at her and expulses her from the team, and she returns home completely disillusioned, then it's revealed that later she was turned into a prostitute herself and still lives in the Poker House. That would have suited the overall tone of the movie. But I guess the authors were just a bunch of cowards.
And does the movie truly suggest that she's not driving home but rather leaving the town towards New York to become an artist? Did she take custody of her sisters?? I mean, wouldn't that be kidnapping if she just takes along her sisters?
