Kathryn Hahn leads this American take on the Sex Education strand of randy teen comedy, starring as a single mother, Eve Fletcher, who rediscovers her sexuality – not least through online porn – after her son, Brendan, leaves for college. In this opening episode, Brendan is ready to move out, but not before an awkward encounter with an ex at a party, while Eve has a brush with inappropriate workplace behaviour. Adapted from Tom Perrotta’s 2017 novel, it is an unflinching coming-of-age tale – for both mother and son. Ammar Kalia
