The repercussions of loss ripple inexorably through Simon Stephens’ 2003 play One Minute. Foreshadowing elements the prolific playwright has developed in his later work, it’s a testing piece that speaks most of all about the currents of loneliness that fan out within the fabric of the modern metropolis.

Can we – should we – control the future? That’s the dilemma faced by anxious parents attempting to steer their offspring through a labyrinthine school system, educational think-tanks, and the teachers shaping young lives. Tamsin Oglesby’s play is an intriguing opener for the Matthew Warchus era: impassioned, fiercely topical, and – with its relatively youthful cast – kicking against the “old” in “Old Vic”. That, and electric guitars as rousing musical accompaniment. The school of rock is now in session.

When is a monologue not quite a monologue? When it is interrupted by another voice, one that contradicts and argues with it. In Cordelia Lynn’s Lela & Co, her Royal Court debut which is effectively and savagely staged in the claustrophobic heat of the upstairs studio space, the drama starts off as a classic monologue, with Lela telling the story of her life, starting with her birth. Then she tells of her rather brutish upbringing up to the age of about 15.

Can you peg a whole play on a decent twist? When We Were Women’s narrative tease pays off interestingly, but takes a hell of a long time getting there. It leaves little space to explore the ramifications of an intriguing revelation, a frustration amplified by the constant chronological cross-cutting in this revived Sharman Macdonald work, first seen at the National in 1988.

“My brother died.” That’s the reality New York-based banker Willem struggles to inhabit when he returns to his estranged family in Amsterdam. There is no sense in Pauli’s loss – a sudden heart attack at 20, cradled by a stranger in the street – nor finality. Willem’s response is to continue the conversation through an elegiac series of letters, countering the abandonment and searching for meaning in both a life interrupted and his own isolated existence.

We all know what the word “addict” means, but what does it feel like to be one? Thirtysomething Emma – a minor actress played with immense conviction and quirky charm by Denise Gough – knows exactly. At one point in Duncan Macmillan’s engrossing new play, she says, “People who aren’t addicted to anything are really missing out, you know?” For the addict lives a life of glory: they feel complete, and loved and satisfied. Yes, that’s it. They love their addiction – and their addiction loves them back.

It felt a bit like we were seeing things. At the fag-end of Edinburgh’s 2015 August of festival mayhem, with extreme exhaustion and input overload mixing to brain-addling effect in the heads of most festival-goers and participants, a hallucinatory, day-glo farce of a show that obsessively repeats just a single word seemed pretty fitting.

Well, here’s an oddity. You Won’t Succeed... is too fragmented for musical theatre, too bombastic for cabaret, and about as profound as a first-draft Wikipedia page. Channelling the self-referential levity of the Monty Python show from which it takes its name would certainly help, but it’s mainly played straight. And what insight into the indelible Jewish contribution to musical theatre does two and a half hours’ investment get you? Those guys…they wrote some great songs. Oy vey.

The political wheel has turned full-circle. When Our Country’s Good was premiered in 1988, it was a barely-veiled protest against Thatcher’s slash-and-burn approach to the arts in general and arts funding in particular. It couldn’t have returned at a more apt moment. Once again the arts are being forced to make a commercial case for their existence, to claw and squabble over scraps of government money, while the newspapers are filled with photos from Syria, of the apparent destruction of Palmyra.

The set turns out to be the thing now that Benedict Cumberbatch's star turn in Hamlet has finally arrived, trailing in its wake a level of expectation, hysteria and scrutiny that might well have made many a lesser actor head for the hills.
