It's a great historical joke that when the Spanish met the Aztecs, it was a blind date made in serve-you-right heaven. At the time, they were the two most unpleasant cultures in the entire world, and richly deserved each other. Still, the story of how stout Cortes blustered, bullied and bludgeoned his way to collapsing an entire empire with a handful of contagious hoodlums is astonishing.
Beautifully shot, impeccably paced, it was a clear, unrelenting look at the National Trust, its friends and enemies, and it makes you want to burn your passport and beg the Luftwaffe to have another go.
