CATTCCH H -UPUTPVN—OIWN CASE YOU MISSED IT...

Doctor Foster RTE Player, until February 6; Season 2, episodes 1 & 2 The excellent 2017 BBC2 series Doctor Foster is back for Season 2.

This is set two years after Gemma Foster coolly and dramatically exposed her husband Simon’s betrayals and forced him to leave town. She and son Tom have been living quietly since, although Tom is increasingly withdrawn and moody.

Then Simon returns to Parminster, with Kate, and their baby daughter, and the tortured power-play between the pair picks up again. Simon tries to turn Tom against his mother — succeeding to the point where Tom asks to live with his father — while Gemma does her best to poison Simon’s relationship with Kate. This is a compelling exploration of the lengths two smart, unscrupulous people will go to destroy one another, with everyone else in their lives seemingly either expendable, or collateral damage.

Suranne Jones (left) is impeccable as Gemma, a portrait of a woman who is both admirable and appalling, with Bertie Carvel as Simon and Jodie Comer, now better known as Villanelle in Killing Eve, as Kate. Catastrophe Channel4 Player, series 4, episode 1 Sharon Horgan and Rob Delaney’s Catastrophe, one of the funniest things on TV, is back, for a fourth — and apparently final — series. At the end of series three, an apparently teetotal Rob had collected a slightly-pissed Sharon from the pub by car, then crashed while she was in the take-away buying a spice bag. The last episode ended with him confessing that he wouldn’t pass a breathalyser as he had been secretly drinking for months.

Series four begins with Rob in court, pleading his case: “I was in a very difficult place emotionally, your honour, as it had not been long since I found out that my wife had masturbated a young student.”

He gets a year of weekend community service, which leaves Sharon wandering around London on her own with two kids, and a brand new shoplifting habit.
