If you can't beat 'em, steal brazenly from 'em. Instead of importing another Scandinavian drama series and slapping on some subtitles, or recycling Fargo or Breaking Bad (or for that matter Deadwood or Twin Peaks), Sky Atlantic has pushed the boat out and created its own slab of sub-zero Nordic mystery, packed with bankable international names. If this extended pilot episode was a reliable guide, it's going to be a tortuous ride on black ice.

Some of the best films this year have been the longest. The one most likely to be remembered is Richard Linklater’s Boyhood, at a modest enough 165 minutes, followed soon after by Nuri Bilge Ceylan’s Turkish masterpiece Winter Sleep, at a weightier 196. Now, close to year end, along comes Lisa Cholodenko’s Olive Kitteridge, bringing with it a considerable tinge of regret that outside a single theatrical outing at this year’s Venice Film Festival, this HBO miniseries is coming to us only on the small screen. At 232 minutes, no less.

That there is something of the Sherlock Holmes about Dr John Thackery – the Shakespeare-quoting, opium and cocaine-addicted surgeon in this Steve Soderbergh-directed 10-part drama set in a New York hospital in 1900 – hasn’t gone unnoted. But although Thackery, played with a certain gruff charm by Brit actor Clive Owen, is clearly a maverick with a clandestine habit, a happy outcome for his patients is rarely on the cards.

Fans of this dense and rewarding odyssey of Prohibition and American gangsterism are doubtless still reeling from the news that its fifth series will be the last, despite the riotous applause which greeted series four. This unwelcome state of affairs perhaps accounted for the vaguely dissociated and dream-like quality of this season opener, which was as much concerned with filling in some of Nucky Thompson's early history as with driving the plot forward into the 1930s.

We've had endless waves of vampires, zombies and Frankenstein's monsters, so why not bundle them all together under the same doomily Gothic roof? Welcome to Penny Dreadful, created by writer John Logan and producer Sam Mendes (who previously worked together on the Bond movie Skyfall), in which we descend into a "demi-monde" of monsters and necromancy in Victorian London.

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.

If imitation is the sincerest form of flattery, the creators of Scandinavia's drama boom could be forgiven if they started behaving like a collection of hysterical Justin Biebers. Not only are their home-grown series hits around the world, they're also being slavishly copied by other broadcasters. The American version of The Killing has been followed by a US take on Danish/Swedish joint effort The Bridge, starring Diane Kruger and set on the Tex/Mex border. Now here's an Anglo-French spin on it, replacing the titular bridge with our beloved Channel Tunnel.

When The Newsroom’s first season started in 2012 the unthinkable seemed to have happened: Aaron Sorkin, creator of The West Wing and Oscar-winning writer of The Social Network, had lost his mojo. Not even his previous, erratic show, Studio 60 on the Sunset Strip, cancelled after its first season, had moments as excruciating as this. 

And so to the third series of HBO's panorama of the Prohibition era, where we joined the denizens of Atlantic City as they prepared to celebrate New Year's Day, 1923. In the finale of series two, we'd seen our chief protagonist, Nucky Thompson (Steve Buscemi), tying off some loose ends as he prepared to take the plunge into full-scale gangsterhood. These included persuading Margaret Schroeder (Kelly Macdonald) to marry him so she couldn't testify against him in court, and despatching his weak and treacherous brother Eli (Shea Whigham) to jail.

American critics haven't been too kind to Aaron Sorkin's new HBO series about a cable TV news programme, for a variety of reasons. At least they had the advantage of understanding the intricate partisan infighting of American politics which forms the show's backdrop, and which will be baffling to many British viewers. On the other hand, nobody is likely to have much trouble recognising the A Few Good Men view of history familiar from previous Sorkin milestones such as The West Wing and, uh, A Few Good Men.
