A documentary about mental health in the best traditions

“Are you looking forward to Christmas?” was always going to be a difficult question. Anthony looked forward to spending it with his daughter and grandchild – as long as he kept taking the medication that allowed him to stay out of hospital. Andrew should have had a happy gathering lined up, except his latest bout of mania had seen him leave the family home. Richard was wrapping presents. A whisk for his mum, because she’d stopped eating; some liqueur chocolates for his gran, the only way to get a drop of alcohol into the old girl.

Dementia is given the operatic treatment

An opera about Alzheimer’s disease might seem an idea calculated to send the most community-minded audience rapidly to the nearest exit. Yet there's a longish history of theatre – musical and otherwise – about loss of memory and the failure of language, from Wagner to Bartók to Beckett to (even) Michael Nyman; and if Elena Langer's new piece for The Opera Group, The Lion's Face, ultimately fails to measure up dramatically to that tradition, it may be because, in approaching the subject from a clinical angle, it imprisons itself in the inescapability of the condition itself, without hope of change or catharsis.

Mental: A History of the Madhouse, BBC Four

Fascinating documentary about the secret history of asylums

Most people’s experience of the 120 or so Victorian asylums that littered the UK landscape for more than a century is, thankfully, oohing and aahing over the “sophisticated and sensitive” conversions they have become, providing “astonishing, unusual and stylish” apartments, as estate-agent-speak has it. Those fortunate enough to move into these beautiful new homes are doing so of their own accord, of course, but many of those held in their previous incarnations would have preferred to be anywhere else at all.

Mediocre circus and bad dance-theatre is what dance is coming to

As we look on the strictly dieting future that undoubtedly waits for the more esoteric arts after Thursday’s election, it’s evident that the dance landscape has already been blighted - and self-blighted, at that. Somewhere in the past few years a loss of confidence in dancing itself has allowed expressive and aesthetic exploration to become increasingly replaced by undemanding scenic gimmicks and numb circus derivations, subtle matters by dim clichés. My depressed thoughts after watching two of the middle scale shows that used to be common all over Britain and now are scarce as hens’ teeth.

Polar Bears, Donmar Warehouse

Mark Haddon's stage-writing debut is a riveting psychological thriller

Mark Haddon is rather making a habit of writing about mental-health issues. His novel The Curious Incident of the Dog in the Night-time was about a boy with Asperger’s and his TV drama Coming Down the Mountain had a character with Down’s syndrome. He charts similar territory with Polar Bears, which also features a character with a mental-health disorder.

Disappointing version of Sarah Kane’s famous study of psychological breakdown

Sarah Kane’s last play is the stuff of legend. Since its first production some 18 months after her suicide in 1999, it’s become a favourite with black-attired drama students, nostalgic in-yer-face drama buffs and mainstream theatres all over mainland Europe. But it is rarely performed in big spaces in this country – apparently because artistic directors feel it would empty their venues. So this version, directed by Grzegorz Jarzyna of Poland’s TR Warszawa on the Barbican's main stage, is a good chance to see what we’ve been missing. Or is it?

Thea Gilmore Rediscovers Christmas

Songwriter ruminates on writing Christmas songs and the internet era

As Bob Dylan has reminded us recently, The Christmas Album is one of those music industry traditions more likely to deserve an ignominious burial rather than praise. Fortunately, Thea Gilmore has galloped to the rescue with Strange Communion, an artfully shaped collection of songs that shines flickering light into the mystical roots of the Yuletide season.
