Untold: The Murder of Air McNair review – save yourself an hour and Google it

Netflix's documentary about the killing of the American football star reveals almost nothing you wouldn't learn in 10 minutes on the web

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.
