Haven’t heard of The Brokenwood Mysteries (we haven’t bothered with the BBC for years. Amazon Prime TV, Netflix and the Internet serve us well), but I do find that shows set in slightly unusual settings often have an extra depth. The US version of The Body was filmed ‘around the back’ of Seattle where the tourists never go, and half the fun of Grimm was that it was filmed in unromantic, non-quaint Portland, Oregon.
