“Of all the anti-social vested interests the worst is the vested interest in ill-health.” The Preface on Doctors that precedes George Bernard Shaw’s The Doctor’s Dilemma finds the writer at his characteristic best: caustic certainly, witty frequently, but in the service of a serious and lengthy invective on the state of British healthcare. Unfortunately the play that follows doesn’t fully share its brilliance, attempting an awkward dramatic marriage of social satire, melodrama and soapbox sermonising.

Alan Ayckbourn refuses to write down to children, and it shows. The Boy Who Fell into a Book is as sophisticated in structure as it is family-friendly in content. The narrative follows nine-year-old Kevin, who is absorbed (literally) into the detective story he is reading: Rockfist and the Green Shark.

“I'm here because I'm concerned,” says scientist Stephen Emmott in direct, measured tones. “I'm concerned about the state of our planet. I think the situation that we're in right now can rightly be called a planetary emergency, an unprecedented planetary emergency.”

As the much-loved Arthur Marshall so profoundly noted, Ibsen is “not a fun one”. One could, with as much truth, say the same about Shakespeare’s rarely staged Timon of Athens: its misanthropy, missing motivations and mercurial shifts in temper do not spell a fun night out to most. It is greatly to the credit of director Nicholas Hytner and his team, therefore, that the evening, if it doesn’t exactly fly by, is consistently engaging, thought-provoking and downright intelligent.

Before Ibsen was, well, Ibsen, he had a successful career as a failed playwright. Producing works on a spectrum between unremarkable and outright bad, he muddled his way through to his late thirties when the publication of Brand derailed what might otherwise have been a spectacularly mediocre life’s work. With the change in fortunes came a change in tone – a welcome and necessary one if the leaden comedy of Ibsen’s early pastoral satire St John’s Night is anything to go by.

At the end of The Riots, the Tricycle Theatre’s verbatim response to last year’s upheavals edited by Gillian Slovo and Cressida Brown, a local Muslim whose home was burnt down in Tottenham was asked to give his view on why it had happened. He summed it up with three words: “Just – angry – people.”

The front door of Ibsen’s A Doll’s House may first have slammed shut in 1879, but it’s a sound whose echoes and re-echoes continue to resonate. The crash of feminist selfhood, bursting through the catatonic tranquility of domestic order, originally scandalised 19^th-century Norwegian society, but with scandal now rather harder to come by, Ibsen’s play has acquired a quieter, but infinitely more pervasive impact.

The Taming of the Shrew celebrates its own rumbustious, raucous (mis)behaviour, so why shouldn't Shakespeare's comedy be granted a production that follows suit? From an opening gambit involving bodily fluids sprayed in the direction of the groundlings to a food fight later that would put the bad boys of Posh to shame, Toby Frow's directorial debut at Shakespeare's Globe turns up the volume to consistently giddy effect.

"I can’t live without horse flesh, if it’s only a piece of cat’s meat on a skewer.” So declares Patricia Hodge’s gung-ho racing fanatic Georgina in this straight-down-the-line revival of Pinero’s 125-year-old caper, which requires cast and audience to subsist on the theatrical equivalent of the latter.

The Arab Spring has arguably been the most important international event after the credit crunch, yet it seems to be of little interest to British playwrights. Parochial, obsessed with writing only what they know, they have been put to shame by Hassan Abdulrazzak, an Iraqi playwright who was born in Czechoslovakia and now lives in London, working as a scientist. His 2007 debut, Baghdad Wedding, was a big hit, and his long-awaited second play is set in Cairo during the revolution that toppled dictator Hosni Mubarak.
