Julian Fellowes, now the Conservative peer Lord Fellowes, left behind the fictional world of Gosford Park and Downton Abbey to give us this sumptuous tour of Blenheim Palace. Nor were its surroundings neglected as vista after vista showed us Blenheim’s lavishly landscaped gardens, fountains and columned monument to John Churchill, ^1st Duke of Marlborough, victorious over Louis XIV. It was his military prowess that led to wealth and Blenheim itself, gifted by the grateful nation and thus an early example of government subsidy.

In a house in Nuneaton, a man calling himself Stinson Hunter lures paedophiles towards exposure, shame and possible prosecution. “We set the profile that is like the rope,” he explained. “And then if they choose to put that rope round their neck and hang theirselves [sic], that is their choice. We have not pushed them.”

Marvellous reviews itself in its title. The story of Neil Baldwin starring Toby Jones was – and is, because you should catch it while you can on iPlayer – simply marvellous. As a dramatic character Neil Baldwin could be mistaken for unremarkable. He has no hidden depths. Positioned somewhere along the autistic spectrum, he is apparently away with the fairytales, but his grandiose fantasies mostly happened to be true.

Angkor Wat in Cambodia is the biggest religious complex ever built. It is also one of the most beautiful and awe-inspiring structures ever created, even now still a working temple with both Buddhist and Hindu connections. It was at the heart not only of a vast medieval city but an empire that dominated southeast Asia for centuries.

When Rachel Bailey (Suranne Jones) told the promotion board at the beginning of this series: “I’m not a liability, I’m a safe pair of hands”, we knew it would be a matter of sitting back and waiting to see in what manner she would heap disgrace upon herself.

A mental blur of airports, stations and dangly cardboard air freshener, minicab-driving has always seemed vulnerable to cliché. The problem facing Vince McKee, David Morrissey‘s driver protagonist in BBC One’s new three-parter, is that the rest of his life is even more dull. His job as a cabbie, involving copious urine, vomit, and a stiletto heel to the neck before he gets tangled up in a criminal gang, is action-packed by contrast.

If Molly Dawes (Lacey Turner) had to find one act of heroism with which to fully incorporate herself into her new squadron before the credits rolled, she couldn’t have planned it better: winched aboard a helicopter, her fist in the groin of the one-night stand who had been undermining her since her arrival to stop him bleeding to death, while Paramore - or some fearsome girl-rock on a more acceptable budget - throbbed in the background.

As unavoidable as death and taxes, as inevitable as the rotation of the seasons, Downton Abbey has created the illusion of time-hallowed permanence in a mere four years. It is often asked how long Julian Fellowes can keep up his script-writing heroics (if it was an American show he'd be marshalling a writing team of dozens), but this opener to series five was so playfully deft and thunderously enjoyable that you'd have to conclude that Downton has become Fellowes's personal fountain of youth.

Let's face it, there are so many big-budget, densely plotted US TV imports around now that it seems a little hackneyed to compare them to buses - but even by those standards, scheduling the two newest ones concurrently seems a little careless. Your choice: Legends, an FBI procedural with a twist from Homeland show-runner Howard Gordon; or Guillermo del Toro's vampire virus horror The Strain.

We think we know the story. As recounted in Philomena, in the 1950s and ‘60s the Irish state and Catholic Church colluded in putting children born out of wedlock up for adoption. A small minority was sent to America, causing a lifetime of trauma and longing in both mothers and children. For portraying one such mother who went in search of her son, Judi Dench was nominated for an Oscar, and the woman she played met Pope Francis. The film’s ending was, if not quite happy, then at least redemptive.
