Britain’s last castle, Drogo, may be only just over a century old, but repair work is going on in a big way – it’s currently the National Trust’s largest-scale restoration project. That provided the excuse for the Time Team special The Edwardian Grand Designer about Drogo's architect, Sir Edwin Lutyens, though attention would surely have come round to him anyway this year, as the designer of World War One cemeteries and monuments, from London’s Cenotaph to the Memorial to the Missing of the Somme at Thiepval (pictured, below right).

You could boil down the content of this new HBO import to an info-bite that reads "two detectives hunt serial killer in Louisiana", but that wouldn't give you the faintest inkling of the pace, mood or texture of what's shaping up as a remarkable chunk of television. You may find it a little slow, and the Deep South accents sometimes cry out for explanatory surtitles, but you're liable to find it seeping into your consciousness like a troubling dream you can't shake off.

There really was astonishing talent on display in The Brits Who Built the Modern World (*****), as full a television panorama of the work of the five architects whose careers were under examination – Richard Rogers, Norman Foster, Nicholas Grimshaw, Michael Hopkins and Terry Farrell – as we’re ever likely to get.

A new series about a team of London firefighters? Probably a bit like Casualty meets The Bill, with added smoke and cats stuck in trees. But no - writer Lucy Kirkwood (of Skins fame) has created a raw chunk of contemporary drama which isn't afraid to rip up a few preconceptions.

By the end of its first series, My Mad Fat Diary had departed far enough from memoirist Rae Earl’s frank, funny source material that the adaptation taking on a life of its own shouldn’t have been a cause for concern. Still, there’s always that niggle when something that got it so completely right first time around returns: can it possibly repeat that magic, or live up to expectations?

Long before the stars had begun walking (and working) the red carpet, this year's British Academy Film Awards were a hot topic. Unfortunately it was for all the wrong reasons. A whistleblower writing for the Daily Mail alleged that many of the Academy's 6,500 members make little effort to consider the full gauntlet of options, often voting for the big-budget American favourites sight unseen.

Crikey. Line of Duty was pumping dangerous levels of octane first time round. For this new series we’re in for an overdose. After one hour the body count is racking up: 3 coppers (shot), 1 witness under protection (burned to a crisp), AN Other (defenestrated). Plus that lovely soft Keeley Hawes has been waterboarded in the lav and has assaulted a noisy neighbour with a wine bottle. If it’s cheering up you need, best retreat to Call the Midwife, where they have window latches you can trust.

Many successful writers turn to their pens having failed miserably at everything else. Ian Fleming, creator of James Bond, and subject of Sky Atlantic’s new mini-series, spent all of his youth failing, but unlike literary contemporaries Graham Greene and Evelyn Waugh, failure seems to have been a thoroughly enjoyable experience.

It’s a brave comic who steps into the spandex zucchini-stuffed loon pants of Spinal Tap. The – if you will – rockumentary will never be done better. But it is 30 years since Marty DiBergi went in search of the sights, the sounds, the smells of a hard-working rock band on the road. So the time is no doubt right for another set of industry jokes to be put into circulation. For the three parts of The Life of Rock, Peter Gabriel and Brian Eno should probably have their lawyers on speed dial.

Mothers and their sons provided the framework for the latest story involving DCI Alan Banks, the character on whom ITV is pinning its hopes to fill the vacancy of the nation’s favourite detective now that Frost and Morse are no more. Peter Robinson’s series of novels has been enjoyed for more than 25 years, selling millions in the UK and translated into more than 20 languages, but it took until 2010 to reach our television screens with Stephen Tompkinson in the starring role.
