I saw it yesterday and, too much different of what I've read here, I simply saw a housewife completely slaved by the crack. Her pain and dreams are so intense that she creates another world, where she is important, famous and mother at the same time. But all of this has a high cost, each price showed in each chapter. Ryan is the crack itself: he is her best friend, her lover and her husband. When he goes away her imaginary world comes to an end: she is cured. The movie just shows us what her mind creates while she tries to get rid of the power of the drug, the crack. What does Ryan think of all this? He is God, such is the power of the drug. He created Melissa's world and He has the power to destroy it when she is cured.
