State of the Union
10pm, BBC Two
Nick Hornby delivers a caustic take on a marriage in crisis in this short-form series following a couple trying to salvage their relationship through counselling. The first 10-minute episode sees Chris O’Dowd and Rosamund Pike skittishly working their way up to attending their first session from the pub opposite. Hornby’s dialogue is on top form as they drily compare the relative merits of cancer to Ebola and dissect their nonexistent sex life. It’s an engaging single-setting watch delivered in micro-form.
