The Netflix documentary strand Untold revisits dark moments in sport: controversy, failure, chicanery and injustice. It has a strong record for finding fascinating stories. Its latest episode, The Murder of Air McNair, looks into the suspicious death of an American football star, which sounds promising – but if there is fresh ground to be trodden, Untold doesn’t find it.
The basic test for an hour-long documentary is whether it can provide a more insightful summary of events than the viewer could get via 10 minutes on Google. Untold only just clears that low bar.
