Theatre conventions are a funny thing. Today, it’s actually quite difficult to see a modern classic dressed in the clothes and performed on the set of its specific historical period. It has to be in contemporary dress. And in a contemporary setting. It’s almost as if producers and directors no longer trust audiences to use their imaginations – poor public, it has to be spoonfed. Ivo van Hove, perhaps the most exciting theatre director since Katie Mitchell, has taken Henrik Ibsen’s 1891 masterpiece and, with help from playwright Patrick Marber, updated it.

Demons, trolls and dead souls have a habit of latching onto Ibsen's bourgeois Norwegians. Surely the best way for actors to handle them is to keep it natural, make them part of the furniture and, in Dostoyevsky's words, "render the supernatural so real that one is almost forced to believe it". But very little seems real or spontaneous in Matthew Warchus's production of The Master Builder.

Greek family smashups at the Almeida now yield to northern agony sagas, less bloody but potentially just as harrowing. In Little Eyolf the 66-year-old Ibsen dissected a failed marriage as ruthlessly as Euripides, Strindberg or Bergman, who was in turn influenced by both of the great Scandinavian playwrights. Something of that pitilessness does emerge in Richard Eyre’s return to the Almeida, chiefly through an unsparing performance by Lydia Leonard and a blend of cold intimacy with powerful nature in Tim Hatley’s designs.

Not so much a national hero, more a national disgrace. That seems to be the current consensus on Peer Gynt as Norway moves forward from having canonized the wild-card wanderer of Ibsen's early epic. It’s now 200 years since Norway gained a constitution, and 114 since Peer first shone in the country's National Theatre, that elegant emblem of the Norwegian language. Where does this uniquely prosperous country stand today, spiritually speaking, and can Ibsen’s myth, creating as potent a figure as Oedipus, Hamlet, Don Juan or Faust, offer any answers?

An Off Broadway play that largely passed without notice in 2002 is now a movie poised to suffer the same fate, notwithstanding the fact that this starry three-hander marks the film directing debut of the prolific American dramatist Israel Horovitz, at the age of 75. So it's no surprise that the older generation gets championed in a script (adapted by Horovitz from his stage play) that finds Maggie Smith playing a nonagenarian who, she tells us, is too old for subtlety.

Ibsen cast a cruel eye on the characters of his most relentlessly symbolic play – wild ducks wounded or domesticated by fate or character. They speak or behave unsympathetically, for the most part, yet the actors must make us care for them. Simon Stone and Chris Ryan sidestep the problem by not only updating the action but writing their own script on the subject, reinventing some of the motivations while keeping the essence. True to some of Ibsen’s main points it may not be, but this is heartbreaking drama, so truthfully acted it would make a stone weep.

Like Ibsen’s titanic character in search of a self, the Barbican’s theatre programme globetrots to find the richest and rarest. Yet it certainly doesn’t reach Peer Gynt's conclusion that home's best. In this case London’s finest and, for most of the year, only showcase for the most innovative of world theatre looked as if it might be hoist with its own international petard: I doubt I’ll ever see a production of Ibsen’s epic masterpiece as shatteringly great as Baltasur Kormakur's pared-down vision for the National Theatre of Iceland in the Pit back in 2007.

In a moment of scalding intensity at the climax of Ghosts, terrified Oswald sees the sun. Throughout the rest of Ibsen’s celebrated drama about the sins of the past, light is fairly absent. Merely cataloguing the disasters that befall its heroine Mrs Alving would certainly indicate a play living up to Ibsen’s bad reputation as the leading dramatist of doom and gloom.

A young man eaten up by fears of inherited disease, a mother who hid the facts of her awful marriage from her son to spare him, but is rewarded with even worse pain: the emotional plotlines of Henrik Ibsen’s Ghosts are huge. While the plot ticks off taboos - incest, rebellious women, euthanasia - deep at the heart of it is an atavistic fear in all of us that we will die in fully conscious agony, eaten up by a madness wished on us by someone’s selfishness or stupidity.

Everything seems so free and easy, so do-as-you-darn-well-pleasey, in the Stockmanns’ fjord-view model home. Cheery friends in bright 1970s clothes drop in to chew the social cud as well as Mrs S’s cooking; only her medical-officer husband’s mayoral brother jars, and surely he’s too daft to be taken seriously. So when the good doctor finds irrefutable proof that the waters of the town’s new spa are poisoned, the weight of liberal opinion will surely back him up and all must be well, right?
