Precious

All the hype about the movie "Precious" is making me want to go see it.. just because Madonna was turned down to produce/direct, Brandy was laughed at to act on and just cuz a few hollywood producers were slapped when they wanted to change the character to a white girl for massive appeal....that's just precious...but how did Mariah get in there?!
has anyone seen it... or looking forward to seeing this movie?
