If you have an aged relative who doesn't like evening TV dramas which are full of sex and violence and swearing and car chases and fight scenes then they will like this. It's got a vibe of other daytime shows such as "Shakespeare and Hathaway" and "Father Brown" with a nod to the 60s Avengers series. 7/10 for being fun but I've only seen episode one. If this descends into the usual BBC PC drivel then I may revise my opinion.
