I agree that no one under 18 should see this movie, too much reality. As a Christian, this gave me a glimpse at what my life could be like without the knowledge that I am loved by God. For those of you who don't have first hand experience with mental illness it will be a real awakening. Susanna makes a choice. She finds the strength that she has and makes positive choices, eventually.
Depression is a reality, sex is a reality, drugs are a reality.
If I could hand out Oscars this would be my choice. It's really a story about a young woman discovering herself and some hard truths which lead her to recovery. These characters are very rich and in depth and very very real. In the beginning Susanna is in defiance and in denial and we are in agreement with her stance as we see through her eyes. But the story takes a turn and her heart softens.
