Rhinoceros ★★★★★

The 1960s were “hilarious”, says one young character in this revival, starring Broadway icon Stockard Channing, of Alexi Kaye Campbell’s 2009 family drama at the Trafalgar Studios. How so? “Oh you know, the clothes, the hair, the raging idealism.” The thought of hippies marching for political causes, smoking Gauloises on the Left Bank or storming the American Embassy in Grosvenor Square, and all the time wearing sandals and beads. Yes, to anyone under the age of 60 that must seem funny.

Like his smash-hit My Night With Reg, Kevin Elyot's first and last plays have a role to play in the history of gay theatre, but do they work? Emphatically not in the case of Twilight Song (★★), completed – one is tempted to say, sketched – shortly before his death in 2014, though four out of five actors at the admirable Park Theatre give it their best shot.

Who'd have guessed that the London theatre scene at present would be so devoted to the numinous? Hard on the heels of Girl from the North Country, which locates moments of transcendence in hard-scrabble Depression-era lives, along comes John Tiffany's deeply tender revival of Jim Cartwright's vaunted 1986 play Road, which tempers its landscape of pain with an abundance of poetry.

Back in Margaret Thatcher’s middle England, teenagers got by somehow. Without recourse to wands or Ballardian games of extinction, we survived adolescence with the help of a story full of people we knew. People (a bit) like us. Every year I re-read Sue Townsend’s chronicles of Adrian Mole, hopeless lovestruck bard of Leicester. And each year he grew up with me, as experience uncovered the texture of Mole’s life. "Phoned Auntie Susan but she is on duty in Holloway." A line like that was simply information at first. A year or two later, it brought a smile, then a conspiratorial laugh.

There's enough plot for a dozen plays buzzing its way through Mosquitoes, Lucy Kirkwood's play that uses the backdrop of the Large Hadron Collidor (LHC) to chronicle the multiple collisions within a family.

Plays with songs in, or more precisely plays with famous songs in, can feel like the uncanny valley of theatre. They’re not quite musicals and not quite tribute shows. They deliver on familiar tunes and disconcert with fresh narrative. You’re constantly wrongfooted by the rush of recognition.

"Maggie the cat is alive: I am alive," or so remarks the feline, eternally frustrated heroine of Tennessee Williams's Cat on a Hot Tin Roof. That self-assessment has rarely been truer than as spoken by Sienna Miller in the terrific West End production directed by Benedict Andrews, in which the actress finally lands the stage role in which she can let rip.

When I say that Matthew Dunster’s Much Ado is revolutionary I’m not talking about the many textual updatings and rewritings, not the lashings of PJ Harvey, nor even the gunfire – weaponised punchlines that cut through the colour and noise of the production.

"What is this, Saving Private Ryan?" a character randomly queries well into the actor Oliver Cotton's new play, Dessert. Well, more like a modern-day An Inspector Calls on steroids, with the volume turned up so high in Trevor Nunn's production that you don't half believe the questioner's wife when she talks about a state of affairs that could be heard all the way to France. After a promising and prickly start, Cotton's hectoring satire of our recklessly self-absorbed, increasingly divisive age devolves into implausibility and hysteria in equal measure.
