I thought it was a brilliant piece of television. Charles Hazlewood has been involved in some great telly lately (I hugely enjoyed the bell ringing programme too).

My only reservation was that it was a bit disingenuous about all the instruments "being made entirely from scrap materials" when in fact there was a bit of cheating: reeds were used in some of the wind instruments for instance. It seemed like some of the makers were more purist than others about what they would include. However that is just a tiny quibble that should not destract from the makers' ingenuity. The achievement and the programme were both to be applauded.
