Watched it when I was ten - not right for anyone under 15, or a mature 14 year old. It was the first time I had ever heard so much swearing in my life. That, a sex scene, a few mob/gangsta/shooting scenes including a dad's hiding of a dead body from his little daughter being played for comedic effect, and a nasty pimp/manager who while surrounded by inappropriately attired girls tries to force another girl into obeying his will and staying under his control, are my memories of this movie. Not images you want stuck in your preteens head, trust me.
In short, older teens may enjoy it, but keep the littler ones away.
