Can it really be a quarter-century since that finest of all Merchant-Ivory film adaptations, Howards End, was first released? So it is, astonishingly, which surely means the time is ripe for a fresh celluloid take on EM Forster's enduring 1910 novel about morality, love and loss in Edwardian-era England.

There are, as I’m sure many of you are aware, four key stages of political change. Denial, anger, acceptance and, finally, documentary film-making.

At its weakest The A Word is just Emmerdale with a twist of autism, especially when the drama swivels away from the little boy to focus on adult infidelities, a grumpy patriarch, sibling rivalries and comedy Poles wisecracking in subtitles.

Sky Atlantic’s German import is an intoxicating mix of intrigue and betrayal, set in the excessive days of the Weimar Republic. Gripping stories and extravagant production meet in the opening two episodes of this brilliantly promising Euro-noir.

Here we go again then. The “first series”, as the BBC are calling it after the fact, of I Know Who You Are slammed the brakes on and juddered to a bewildering halt back in the middle of August. Almost everyone who’d sat through the plot dodgems of those 10 episodes will have had the same reaction: eh?

Forty years ago Whispering Bob Harris made a documentary about Queen. He eavesdropped on them as they recorded the album News of the World and then followed them around America on tour. The film was never broadcast but the footage was exhumed for this anniversary and stapled together in Queen: Rock the World (BBC Four), the latest in the BBC's prancing cavalcade of recent documentaries about the band (see sidebar).

Laughable though it frequently – oh go on then, always – is, Strike Back is obviously a target-rich environment for those of a thespian persuasion. The likes of Richard Armitage, Andrew Lincoln, Robson Green and Michelle Yeoh have passed through the show’s bullet-spattered portals over its previous five series, and for series six Warren Brown gets the gig as the special forces maverick out for retribution.

There was much more to Brendan J Byrne’s engrossing, even-handed documentary 66 Days (BBC Four) than its title might at first suggest. The timeline that led up to the death on 5 May 1981 of the IRA prisoner provided its immediate context – an increasingly dramatic one as the countdown of Sands’s hunger strike nears its inexorable conclusion.

And now the end is near… and so Inspector George Gently faces his final case. Deemed too political to be broadcast in its original slot in May – 10 days before the General Election – Gently and the New Age was postponed until 8.30pm last night.

Repetition can help clarity. It emphasises significance, and shines a light more directly onto something hidden. It can guide us gently into an area we might have otherwise circumvented, and urge us to stare at something for long enough to see beyond, and transcend previous, long-held opinions. It can also, of course, become very tired very fast and that was, sadly, the case with the third series of John Morton’s BBC mockumentary sitcom.
