Extremely excellent realistic portrayal does not equal enjoyable to watch. Unlike Winter’s Bone, Granik’s Down to the Bone is a slice of life-mostly monotonous, pathetic & unwatchable– as opposed to a film focused on an extreme moment in someone’s life as a microcosm of the ills of an impoverished community with concrete peaks, valleys & resolutions expected from traditional narratives. If the subject matter interests you, the personal struggle against drug abuse of an average person, you should watch it.
