If it only had a heart. Animal cruelty, a sadistic green-faced witch, flying monkeys: L Frank Baum’s story, which spawned the MGM movie that made Judy Garland a star, is downright grotesque. And when it’s not unsettling you with its rusty Tin Man, straw-brained Scarecrow and camp Cowardly Lion, it’s making you gag on its sickly platitudes about best friends, family and finding your heart’s desire in your own backyard.

Upper-middle-class familial relations are placed under an unflattering spotlight in Joanna Hogg’s rich, resonant and often scathingly comic drama, which triumphantly harnesses the power of the unsaid and the unseen. Like its predecessor Unrelated, Archipelago is a superior, stylistically distinct work that is utterly, almost cringingly credible.

At the moment, most of the energy in British new writing seems to be coming from American and Irish playwrights. This is such a regular phenomenon, one that comes around every few years, that it seems idle to speculate on the reasons for it; surely, it’s enough to welcome another new talent from Ireland? As well as being the artistic director of Tall Tales theatre company, Deirdre Kinahan is a prolific playwright. Her UK debut, Moment, opened last night at the Bush Theatre in west London, and is an engrossing study of a dysfunctional family.

For those not of Jewish heritage and who may not know the significance of the title, Friday-night dinner is the hub of a Jewish family’s week, when they gather together for a special dinner and prayers. It’s a (very) rough cultural equivalent of a Sunday roast or the Thanksgiving meal, and even for many non-religious Jews who dispense with the traditional menu and prayers, there’s a three-line whip on attendance.

Ayub Khan Din’s belated sequel to 1999’s East is East moves the story on by five years as we revisit the Khan family in Salford in 1976. East is East (directed by Damien O’Donnell) concerned chip-shop owner George Khan’s determined attempts to marry off his sons to Pakistani girls, while West is West (directed by Andy DeEmmony) centres on Sajid, the youngest brother whom we previously saw permanently in a hooded Parka.

Another of Mike Leigh’s finely nuanced ensemble pieces features some of his repertory players - including Jim Broadbent, Lesley Manville and Ruth Sheen - who have developed their roles and dialogue in collaboration with the director.

From being virtually ignored by theatres and playwrights, the issue of climate change now threatens to swamp the programmes of our flagship theatres. If this is a good thing, meaning that the heat has been turned up on the debate, can public interest be maintained at this rate? Is the topic at all sustainable? After Greenland opened at the National Theatre last week, now it’s the turn of Richard Bean’s new play, which had its premiere at the Royal Court last night, in a production starring the superb Juliet Stevenson. And if the National's contribution to the debate was a bit too cool, Bean's play is much hotter.

So many stage shows (musicals, mostly) are these days fashioned from films that the arrival of Rabbit Hole reminds us of the time-honored habit of plundering yesteryear's Broadway hit for this movie season's trophy-minded bait. And so we have Nicole Kidman Oscar-nominated for her turn as the grieving mum in a part that won Cynthia Nixon New York's Tony Award five years ago.

Probably the only person who would try and tackle cancer in a "humorous" way in Britain would be Frankie Boyle, and God knows he's not funny. No doubt we'd be treated to jokes about how unattractive women without hair are, or something equally enlightening. But while the British would come at this from an unpleasant angle, it is normally squeamish American TV which is in the true avant-garde. Hence, The Big C on More4.

If the jewel in Sky Atlantic's crown is the award-guzzling Boardwalk Empire, great things are also expected of its new cop-opera Blue Bloods, judging by the number of trailers spattering the Sky networks. It's the Dynasty of law enforcement, chronicling the relationships and travails of the Reagan family of New York.
