Query: Great performances!

I was sucked in by all of the magnificent performances of this drama/tragedy. This film is slow but none of the scenes are wasted. All of the performances are outstanding but Sam Rockwell clearly surpassed the others as a man who found God after he tried to commit suicide. His gradual mental deterioration throughout the movie was heartbreaking and poignant to watch. I felt empathy for all the characters even though they are quite depressing and definitely aren't perfect people. See it for the realistic and contemplative character study and fabulous performances.
