Sex Education (Seasons 1–4)

Sex Education (2019) is a British Netflix comedy-drama you can watch online on iFILM. Asa Butterfield plays Otis Milburn, a teenager whose mother Jean — Gillian Anderson in full therapist mode — turns their home into an involuntary masterclass in human sexuality.

Otis absorbs everything and understands almost nothing about his own feelings. When sharp-tongued Maeve Wiley (Emma Mackey) spots his accidental expertise, the two start a word-of-mouth sex therapy service for their classmates — questions the school counsellor would never touch. Best friend Eric (Ncuti Gatwa) is the show's emotional anchor, loud and loyal in equal measure. Connor Swindells plays Adam, the headmaster's son who projects aggression over everything he cannot name. Each character gets a proper arc; the series runs them in parallel without rushing anyone toward a tidy resolution.

Four seasons and 32 episodes later, Netflix closed the story on its own terms. Ncuti Gatwa went from this role straight to the TARDIS as the new Doctor Who. Stream all seasons of Sex Education online on iFILM.
