When Sex Education began in 2019, few people would have guessed that some members of its young(ish) cast would eventually become the new Doctor Who (Ncuti Gatwa), Emily Brontë (Emma Mackey) or be larking around in Barbieland (Connor Swindells, plus Mackey and Gatwa again). But four years later, and with some of its actors stretching reality a tad by still playing high-school kids, the time had definitely come to say farewell to Laurie Nunn’s frank and funny comedy-drama.

With Moordale Secondary being shut down, Otis (Asa Butterfield), Aimee (Aimee Lou Wood), Ruby (Mimi Keene) and Eric (the twice aforementioned Gatwa) have been relocated to Cavendish Sixth Form College, an educational haven for wellness and respect where gossip is banned and a Technicolor-clothed acceptance of difference is demanded. This series will never have been a particular favourite of the alt-right (what with its laser-focused intention to pursue as much diversity and inclusivity as possible) but the Daily Mail/GB News brigade will literally puke themselves silly at every single scene here. Having obliterated the nation’s youth for their ‘woke’ fundamentalism, it shouldn’t come as much of a surprise to them when a key writer for that constituency chucks almost every shade of identity into the mix for this final salvo.

While it does straddle that tricky line between mass representation and self-parody, most characters get their moment in the Welsh sun, while behind the façade, seemingly ‘perfect’ individuals are seen to be flawed and (get this) all-too human. Each storyline may get wrapped up too satisfactorily for some, but the last couple of episodes ride a delicious wave of emotional momentum.
