The rule doesn’t always hold good, but in a television drama a fairly reliable kitemark of quality is when the opening credits list the cast and you’ve heard of them. The title sequence of Unforgotten promised Trevor Eve, Nicola Walker, Sanjeev Bhaskar, Tom Courtenay, Gemma Jones, Ruth Sheen, Peter Egan, Hannah Gordon, Bernard Hill, Cherie Lunghi and Tom Cobbleigh. OK not Uncle Tom, but you get the picture. A sizeable chunk from the senior end of Spotlight don’t turn out for any old half-baked crime drama.

TV series about the clergy are usually farcical, self-deprecating or just plain wet, so it's a pleasant surprise to find one that's prepared to slug it out with issues of good and evil. Compared to Rev, a wistful tragi-comedy about managing the terminal decline of the C of E, Midwinter of the Spirit wants to mount up and ride into battle against the Ungodly.

It began with the sinking of the Titanic all those series ago. However many holes Julian Fellowes has seen fit to build in to the design, his own ocean-going liner has valiantly refused to go down with all hands on deck. But by Christmas we will have seen the last of Lord Grantham and his household, until such time as they all get resurrected for a big-screen reunion, even the Dowager Countess Maggie. For some, the bereavement will be too much and they'll rewind to the start of the first boxset. For others it'll be like the end of a long prison sentence.

“Breezy” isn't a word we associate with Ray Winstone. We’re more used to something like “big slab o’ bastard”, the epithet he got (they were biased Glaswegians, admittedly) most recently for his appearance in Robert Carlyle’s The Legend of Barney Thomson.

The clinically white buildings of the Royal (Dick) School of Veterinary Medicine, nickname Dick Vet, are just outside Edinburgh, with departments for wildlife, exotic animals, domestic pets and large animals, from horses to cattle. It was founded by William Dick, a human anatomist, in 1823. It is among the top 10 such schools in the world, and came to worldwide fame by cloning Dolly the sheep.

Drama is all about secrets revealed, discoveries unfurled. Black Work was straight into that territory from the first scene. A man and a woman sat in a car, taking the solace from each other that they couldn’t find at home. As ever in such a scenario, you promptly wondered if or when they’d be caught in the act. This was especially so given that the woman was played by Sheridan Smith, who starred in just such an adultery drama not that long ago.

The title is, of course, ironic. The house in question is a rambling refurbished dwelling deep in the Lake District, reached by driving through lonely wind-blasted valleys and across rain-thrashed hillsides. It's where a former policeman, known only as Robert (Christopher Eccleston), has come to heal himself after a traumatic near-death experience.

Who says satire is dead? After this, I would imagine just about everybody. According to Jon Culshaw, one of the prime movers in ITV's new puppet-CGI farrago Newzoids [*], this isn't just Spitting Image revisited because "the puppets have got more of a spikiness, more of an edgy exaggeration to them." You think? One other difference he forgot to mention was that Spitting Image was often really rather good.

DNA: there’s a lot of it about. Random Googling reveals that, just in the past few days, a new study claims arachnophobia may be programmed into our DNA, that the British share 30 percent of their DNA with the Germans, while in the USA they’re using DNA to track down dog owners who don’t scoop poop. This last may not be what Leicester University geneticist Professor Alec Jeffreys had a mind when he developed techniques in DNA fingerprinting.

“Something strident and stirring – play to us now, please!” demands Martin Clunes’ Sir Arthur Conan Doyle to the piano-playing vicar’s wife, on apprehending that their conversation is being eavesdropped on. Sherlock Holmes himself could hardly have responded more adeptly to frustrate the eavesdropper, and as Conan Doyle’s pursuit of the intruder leads him to a sinister, candle-lit shrine containing the vicar’s daughter’s long-lost favourite doll, it’s clear that ITV has a new thriller both strident and stirring on its hands.
