Sunderland 'Til I Die (2018–2020, Netflix)

Sunderland 'Til I Die followed Sunderland AFC through back-to-back relegations from the Championship to League One, capturing the human devastation of institutional collapse with unprecedented intimacy. Netflix filmed 500 hours of footage across two seasons. The documentary became one of the streaming era's most critically acclaimed sports productions, winning the Royal Television Society award for Best Documentary Series. It generated so much sympathy for Sunderland that the club's shirt sponsorship inquiries tripled after the first season aired. Season 3 followed their 2018–19 League One title.
