Jennifer Aniston excels as small town cashier, stifled in a rudderless marriage and miserable at her boring job, who has an affair with a younger co-worker, leading to a series of confounding personal events. Black comedy is initially bright and biting, subtle about its comedic elements and characters while gently satirizing the middle class aesthetic. Unfortunately, the film takes a wrong turn late in the second-half and never quite recovers, leading to an emotionally unsatisfying finish. The performers are all terrific, especially John C. Reilly as Aniston's pot-smoking husband; but, as the screenplay loses steam so do the actors, and the final events are mechanically offbeat--engineered to be quirky. **1/2 from ****
