"The Substance of Fire" is a slice of life film which tells of a small time New York Jewish holocaust-survivor book publishing purist and authoritarian patriarch to his adult children; two sons, one daughter. The slice has to do with the slow disintegration of his family owned publishing business and his mental health in the wake of his wife's death, financial woes over his inability to adapt to market demands, and his advancing age.
The film sports a solid cast and excellent performances, especially by Rifkin, and is artistically and technically good. However, when all is said and done, the viewer may wonder why they bothered watching as the story just begins and ends with no apparent reason being; no moral, no message, no lessons, not compelling or thought provoking and difficult with which to empathize. Likely to be of most interest to those who like "all in the family" relationship films.
