It was delivered in a laudably direct style and McAlpine's openness and comfort with the camera combined to make strong and straight TV, though a bit of a stretch at half an hour and I feel slightly guilty even saying that, given the subject.
Following straight after NZ Story on TV One there was another heartwarming hour of stuff about us, except this one, called, equally un-zippily, This Town, was a big cuddly colour piece.
Managing to be both uncommonly beautiful and charmingly folksy, Saturday's episode offered a ramble through a colourful collection of some of the towns of Central Otago, small and smaller.
Made by the people who made North and South with Marcus Lush and Intrepid Journeys with everyone else, This Town turned its twinkly eye on an interesting local from each locality.
A duck shooter in Becks, feeling emotional with his mates in the moment, said, "It's not about ducks."
In Roxburgh, the wife of the man who built his own power station said, "There's doers and there's not doers" and she seemed to know about that sort of thing.
In a Stephen King moment, in sleepy Alexandra two giggling young sisters told of the day the pie cart unexpectedly exploded, never to rise again.

Rachel Hunter settled for telling a tiny terrible dancer, "You're so cute", though he clearly wasn't. Just deluded.
The presence of choreographer and former Michael Jackson dancer Cris Judd has had the unfortunate effect of bringing waves of dancers on to the all-talent talent show.
