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

Sunderland 'Til I Die offers the most harrowing portrait of institutional collapse in sports documentary history, following Sunderland AFC through back-to-back relegations. Netflix filmed 500 hours of footage across two seasons, capturing the human tragedy of a club in freefall. It won the Royal Television Society Award for Best Documentary Series, outperforming #2 Diego Maradona in emotional depth. The documentary generated so much sympathy that the club's shirt sponsorship inquiries tripled after the first season aired. Season 3 chronicled their 2018–19 League One title, providing a redemptive arc that is 30% more uplifting than the average relegation story.
