They say "never meet your heroes". That may be true, but it forms the premise of a new TV drama concerning two of the world’s most famous children’s authors – Beatrix Potter and Roald Dahl – who encounter each other at opposite ends of their life. 

At first glance you might mistake Bridgerton (Netflix) for the latest effusion from the pen of Lord Fellowes, since it conforms so closely to the Fellowesian pattern of manners, money and mores among the English aristocracy. Even the title sounds like a mashup of Downton and Belgravia.

Having launched their new-look All Creatures… back in September to wild acclaim, it was a no-brainer for Channel 5 to commission this Christmas Special. The only mystery is why they didn’t schedule it for Christmas Day, where it would probably have seen off most of the not-very-thrilling competition.

If you’ve loved every episode of Ben Elton’s Shakespeare and Co comedy, you’ll know what to expect – but you’ll have to swallow bittersweet pills from only two of the excellent ensemble who’ve given us such comfort and joyous rapid-fire delivery of wordsmithery over three series (and on the London stage, as it was before mid-March).

The fifth and final film in the Small Axe series is titled Education. At first, it appears this refers to the education of the central character, 12-year-old London boy Kingsley Smith, impressively played by Kenyah Sandy, who’s transferred to a disgraceful “School for the Educationally Subnormal” after being disruptive.

Breaking away from the outlandish shenanigans in Little Big Bear in the Canadian wilds of its first two series, this third outing for Tin Star brings Jack Worth (Tim Roth), wife Angela (Genevieve O’Reilly) and daughter Anna (Abigail Lawrie) back across the Atlantic to Liverpool to confront dirty secrets they’ve been running away from for 20 years.

The seductively breathy Joanna Lumley supplied the voice-over for this hugely entertaining romp through the history of Coronation Street, celebrating “the Diamond Jubilee of the world’s longest-running soap.” Yet wasn’t the uber-posh Lumley, scion of the British Raj, a discordant choice for this long-running saga of Mancunian folk?

Anyone who expects traditional narrative in Steve McQueen’s five Small Axe films about the black experience in the London of the 1970s and 80s will be disappointed.

The story of the raid on dams in Germany's Ruhr Valley by the RAF’s 617 Squadron in May 1943 has become a subject of perennial fascination as well as a potent national myth.

Throughout its preceding five episodes, The Undoing (Sky Atlantic) has skilfully, if a little shamelessly, kept the fickle finger of suspicion in perpetual motion.
