This movie is way too long for the events it depicts, and way too dark both in content and in the film. I understand the under lighted scenes are supposed to reflect the darkness of depression, but it's as annoying to watch two hours of no one bothering to turn on a light bulb as it is to watch the scenes being drawn out for time needlessly.
I also found it was a completely predictable story.
That being said the score was really good, as was the acting from everyone in this movie. If a half hour more was moved to the cutting room floor it wouldn't be missed and the movie would be better for it, but it would still be a movie few people will want to sit through, a dark drama on clinical depression.
