Sunshine Cleaning is a great addition to that unidentified genre of grown-up comedies populated by other great entries like Your Sister's Sister and Enough Said. It is however, less of a comedy than it is a heart-warming emotional tale. Powered by outstanding performances from Amy Adams and Emily Blunt, it ultimately evolves into a character study of failed potential and validation seeking. Sunshine Cleaning is enjoyable, satisfying to a fault, and provides an interesting peak into the lives of its characters.
