Hallelujah! At last the BBC have commissioned a Stephen Poliakoff series that makes you want to come back for episode two (and hopefully all six), thanks to a powerful cast making the most of some perceptively-written roles.

Persistent depression is debilitating and terrifying, as Alastair Campbell illustrated vividly in this punchily-argued film. We first saw him looking like a disturbed, miserable ghost, as he described in his video diary a sudden plunge into depression at New Year, 2018. He seemed to be ebbing away before our eyes.

It’s remarkable that this meandering observational documentary about the five square mile airport west of London has stretched to a fifth series. Heathrow may have 77,000 staff and expect 80 million passengers to pass through this year, but that doesn’t mean everything they do is interesting.

Have we passed peak Hatton Garden? It’s now four years since a gang of old lags pulled off the biggest heist of them all. They penetrated a basement next door to a safe-deposit company, drilled through the wall, and made off with many millions quids’ worth in diamonds, cash and the like. All but one of them ended up in prison, where they will probably see out their days, being all of them well past pensionable age.

Is there some tongue-in-cheek irony in BBC Two starting a five-part biographical documentary on Margaret Thatcher this Monday?

In 2010, Maxine Peake starred in The Secret Diaries of Miss Anne Lister, but this new dramatisation of Lister’s life has been gestating in Sally Wainwright’s brain for 20 years, and finally arrives under the auspices of the BBC and HBO.

This year, Cannes has been adamantly defending traditional cinema, with more than a few jibes at Netflix (who remain persona non grata at the festival), but that hasn’t stopped them screening two episodes of Nicolas Winding Refn’s new Amazon TV series, Too Old To Die Young. Refn has gone on record stating that his latest project is still cinema — a 13-hour film that shows all the verve and ambition you’d expect from the Danish auteur.

This is a toothsome treat for Sunday nights and one of those rare occasions when the BBC has got hold of the kind of nifty comedy series that Netflix usually pumps out. What We Do in the Shadows started out as a New Zealand vampire flick in 2014.

In the week that the Jeremy Kyle show has been yanked permanently off air after the death of one of its vulnerable guests, the timing couldn’t have been better for the BBC to show how sensitively the old-school broadcaster handles contributors with mental health problems.

It is a cliché that never grows old. From Fawlty Towers via The Office all the way through to (so we are told) Fleabag, a great half-hour comedy that bows out after two series cements its place in the pantheon by ensuring posterity wants more. Twelve episodes seems to be the platonic ideal of the perfectly proportioned sitcom.
