‘Too Much’ has the chaos of ‘Girls,’ but it’s at its best in moments of calm

In this adaptation, Dunham, who penned or collaborated on all ten episodes and also served as director for several, has chosen not to act but instead introduced Megan Stalter from “Hacks” as her stand-in character, Jessica. (Dunham portrays Nora, Jessica’s depressed older sister, primarily from a bed.) Since both characters are American expats residing in England and involved with musicians, some aspects of their story may draw inspiration from the authenticity of their shared experiences.
