Streep and Jones, maybe our two finest actors, give virtuoso performances in this excellent treatment of the decay and salvation of a long-term marriage. In their hands, "Arnold" and "Kay" become live people whose suffering and longings we recognize painfully. Blessedly, none of the usual stereotyping or cheap gags spoil the authenticity. The direction and editing are a bit jerky at times but this seems a minor flaw, considering the film as a whole.
Pros great actors, excellent writing, important subject
