The past decade has seen plenty of films focused on men struggling to graduate from their carefree 20s to their more responsible 30s; picture anything starring Seth Rogen to get the idea. Fewer films have focused on women who don’t conform to tired societal expectations regarding marriage and motherhood.

This British comedy aims to bring some equality to the subgenre and has Broadchurch’s Jodie Whittaker as a woman, crippled by the death of her twin, living a regressive lifestyle in her mother’s shed, making films with her thumbs and refusing to grow up. It’s interesting territory but tackled with insufferable tweeness and an overload of tiresome quirk. Whittaker just about makes it watchable, but any vague insights on the perilous journey from 29 to 30 are thin on the ground thanks to a tone that can be best likened to a label on an Innocent smoothie. For a far superior female view on stunted growth, check out Young Adult or Bridesmaids.
