"Slow Horses" is about MI-5's worst agents. Those who have screwed up in the field are sent to work on low priority garbage work until they retire or quit. Takes about one and a half episodes to hit its stride.
"Landman" is about a Texas oilman whose job is to manage everything from the drilling to getting the product to market. Billy Bob Thornton is a great anti-hero; divorced, alcoholic, in debt, and smarter than everyone else for all the good it does him.
