Always leave them wanting more, a wise man once said, and there can’t be a single fan of Mum who doesn’t want its creator, Stefan Golaszewski, to change his mind about making the third series the last. But then, when you achieve perfection perhaps it’s best to sign off at the top; the finale was just scrumptious.

The surprisingly touching conclusion to BBC Two’s five-part chronicle of the Thatcher years was a masterpiece of contemporary history. Congratulations to producer Alice Fraser, director Pamela Gordon, and composer Alexandra Harwood for very fitting and emotive music (for once).

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.

Bognor Regis was once renowned for its restorative climate and was much favoured by George V (he awarded the town the “Regis” tag), but times have changed if Toby Jones’s new series is anything to go by. The Bognor we see in BBC Two's Don't Forget the Driver is a crumbling ghost town, all run-down bungalows, pensioners and, it seems, an underclass of exploited immigrants.

When they were children the interviewees in this film – the last survivors – were taken away in incomprehensible circumstances, on their way to be murdered for who they were, in Germany and places further east.

After the heart-breaking ending to the third series earlier this year, which covered the death of William Shakespeare's young son, Hamnet, it was back to the comedy for this seasonal special. 

In 2017, the BBC Wales team with director Rhodri Huw filmed a Christmas show in the old 1888 Coal Exchange in Cardiff, now a hotel. Tom Jones and Beverley Knight’s Gospel Christmas was an exciting and upbeat show, which ended in an electrifying “Born in Bethlehem”. Knight was jumping around as if she’d had springs fitted, the radio mic on her back somehow staying attached to her.

The toughest subject you can imagine: when, and how, would you choose death over life? This riveting film examined that excruciating dilemma within the legal frameworks on offer to some of the terminally ill in the United States.

Peter Jackson has form when it comes to re-examining cinema history. In 1995 he made Forgotten Silver, a documentary about Colin McKenzie, a New Zealand filmmaker who not only made the first sound recordings but also invented the tracking shot and the close-up, and pioneered colour film, back in the 1910s long before his counterparts in America and France. His impressive oeuvre was lost until Jackson found the abandoned cans of film in a garden shed.
