Watched it last night. Not as graphic as I thought it would be (based on some comments here)...but it got the points across clearly. Overall, it had an uplifting theme to it, as I could imagine that most incest survivor's lives in adulthood would be much worse than Precious' was. My only guess, is that her fantasy (mental) removal from the actual physical acts being performed on her helped compartmentalize and detach her from the memory of it. In the end, she had friends, two kids which she loved and adored, two kids that had a loving mom in return, and most importantly, seemed to have broken the cycle of abuse. A perfect life...by no means. But one which was much better in the end, than at the beginning.
I give it a 7 (out of 10) for me.
