ONE TRUE THING could be described as a more thoughtful and quiet TERMS OF ENDEARMENT in the sense that it addresses relationships between mothers and their adult daughters--but this time the dying process is reversed as Kate Gulden (Streep), beloved wife and homemaker of the June Cleaver/Martha Stewart variety, is suddenly stricken with cancer. Her adult daughter (Zellweger) is asked to come home to help her father deal with daily chores and, presumably, to prepare for the death vigil. On the surface, it sounds like the plot of a network movie, but the performances of Meryl Streep and Renee Zellweger raise the quality far beyond that. Streep, in particular, continues to amaze. After twenty years at the top of her game (and earning her 11th Oscar nomination for this role), she still finds the heart of every character and creates the nuances that complement them. This performance ranks with her best work in SOPHIE'S CHOICE and THE BRIDGES OF MADISON COUNTY. But Ms. Zellweger is no slouch either; though the character of Ellen Gulden is initially off-putting, this young actress has enough imagination to show us the evolution of a self-obsessed careerist (like her father, played incisively by William Hurt) to a mature and compassionate woman. As the overlooked son, Tom Everett Scott registers strongly, as he did in THAT THING YOU DO, with an emotionally poignant turn as Streep's alter-ego: a son with as much joy of life as his neglected mother. The movie also features a lovely, understated score by Cliff Eidelman and sensitive direction from Carl Franklin, who is a smashing success in every genre he attempts. Highly recommended.
