Not too long ago it would have been unthinkable for a BBC One Sunday-night period drama series to tell of one woman’s love for another. Whatever anyone thought of it – and not everyone bade it the hearty welcome it merited – Gentleman Jack has shifted the dial.

As Russell T Davies’s doomsday odyssey reached its endgame on BBC One, feisty grandma Muriel (played by indestructible Anne Reid) got to deliver the moral of the story. With the Lyons clan gathered round that now-familiar dining table, she spelt it out for them.

Does every generation suffer its own form of doomsday paranoia? In Stephen Poliakoff’s BBC Two drama Summer of Rockets, it’s the late 1950s and everybody’s convinced they’re about to perish in a nuclear holocaust.

Writer Dan Sefton’s four-part hospital drama reached a modestly satisfying conclusion as the phantom killer stalking the wards was finally unmasked, following the usual twists and misdirections obligatory in thrillerland.

The porn was a bit disappointing, was it not? Dear old Ted, no longer romantically active, admitted to being a user. The Superintendent Hastings fanclub sighed for sorrow to witness him toss away his status as an essentially decent heartthrob for the Saga generation. Sorry for your loss, ladies. It was also disappointing because the high-risk act of wiping his laptop turned out to have such a bathetic explanation. The 50k lying around in a brown envelope he clearly deemed to have less pressing potential for embarrassment.

Peer down the glassy dark and you’ll see them. White bubbles trapped in the frozen lake which appear to be rising to the surface. Look through the permafrost this way and you’re seeing into the past: as the ice melts, gas which was captured and stored tens of thousands of years ago when woolly mammoths and sabre-toothed cats stalked Alaska is released into the atmosphere. Each slick of melt water is another decade returning to the rivers. A scientist pokes a flare towards a hissing vent and the lake burps fire.

Great, a new drama not by the Williams brothers. Instead it’s Dan Sefton’s second iteration of his medical thriller Trust Me, last seen in 2017 starring Jody Whittaker. Since she’s off being Doctor Who, the new series has a new cast, with John Hannah as Dr Archie Watson and Ashley Jensen as physio Debbie Dorrell.

The problem with Fleabag (BBC Three/BBC One) is that it makes almost all television look pedestrian. It’s like the difference between Fleabag’s scummily inadequate boyfriends and the unattainable perfection embodied by the cool sweary priest. Earth vs heaven. Water/wine. And now it is gone.

Piers Morgan hated This Time with Alan Partridge (BBC One) and predicted it would be pulled before the end of the series. This may be taken as a kitemark of quality. And yet the prime target for Steve Coogan’s satire was no voice in the wilderness.

Congratulations to Stephen Graham, guest-starring in this fifth season of BBC One’s Line of Duty, for still being alive at the end of episode one, a favour not routinely granted to headline names in Jed Mercurio’s diabolical labyrinth of deception.
