Aircraft hijacking is a ghoulishly popular theme in films and TV, but Red Eye brings a slightly different twist to the perils of air travel. This time, North China Air’s Flight 357, from London to Beijing, hasn’t been hijacked, but it has become the scene of a string of inexplicable murders, carried out by unknown assassin(s) as it cruises at 40,000 feet.

The screenwriting debut of actor Andrew Buchan, Passenger ends up resembling a bunch of ingredients looking for a cake. While characters come out with such meta-observations as “this isn’t Twin Peaks” and “this isn’t Broadchurch” – Buchan having been one of the stars of Broadchurch – Passenger contains echoes of both of them, and rather louder ones of Happy Valley.

There isn’t a troupe officially called the Worshipful Company of British Character Actors, but there probably should be, given the sterling service it does for the nation, acting in prestige TV dramas based on real events. Toby Jones and Monica Dolan regularly top the bill in this genre, as they do in ITV’s Mr Bates vs The Post Office.

TV viewers can hardly complain about a lack of choice these days, though they might baulk at funding an ever-lengthening list of subscriptions.

This skilfully-woven drama about an NHS doctor being battered by professional and personal pressures is undoubtedly timely, and benefits greatly from being written by Grace Ofori-Attah, a former NHS doctor herself. Her inside knowledge lends weight and verisimilitude to scenes depicting admission procedures or the way the treacherous politics of NHS hierarchies work, and perhaps most significantly, how internal investigations are conducted.

Endeavour first landed way back in 2012, and suddenly here we are, bidding it a final farewell after the end of its ninth series. Not everybody learned to love Shaun Evans as the pre-John Thaw Inspector Morse, but some of us may even have come to like the new boy better.

A disclaimer in the opening credits confessed that some scenes in this three-part history of disgraced Labour MP John Stonehouse had been “imagined for dramatic purposes”, but there was no need. The man’s life story fell comfortably into the “you couldn’t make it up” zone, and there wasn’t really much that screenwriter John Preston needed to add.

In 10 series stretching over the last 18 years, ITV's Doc Martin unobtrusively became an enduringly popular household name, but it finally reached the end of the road with this Christmas one-off. Unless, of course, there’s a prequel, a sequel, an origin story or a transformed internationalised version from Netflix.

Although plaudits have been rolling in for Lauren Lyle’s smart and sparky portrayal of the titular detective in Karen Pirie (ITV), getting to the end of the third and final episode felt like a long slog.

Despite the jarring effect of having British actors speaking colloquial English while purporting to be Dutch policemen working in Amsterdam, the second series of ITV’s Van der Valk arrived at its third and final episode feeling as if it had reached its comfort zone.
