A director who is “passionate about biology”; a humorist who “hardly ever mocks”; an artist who speaks fluently about the origin of species; a non-musician who has directed some of the best-received opera productions of the modern era; a doctor with his own profile on IMDB. In short, a man who puts the “poly” into “polymath” – and like as not does it in Greek. Don’t you just hate Jonathan Miller?

David McVicar’s Rigoletto hurls full-frontal nudity and an orgy at the audience within its opening minutes – dramatic grenades to clear the well-worn ground ahead. Back in 2001 this may have been enough to shock-and-awe, but a decade and a couple of revivals on and it takes rather more. And more we certainly get in the current revival. Not only does Italian superstar tenor Vittorio Grigolo take his turn in the Duke’s tight britches, but John Eliot Gardiner takes charge in the pit for this, his first Rigoletto.

New Royal Opera director Kasper Holten has announced a 2012-13 season in which big-name favourite operas and world opera stars are threaded through by 19th-century rarities and British operas. ROH music director Sir Antonio Pappano conducts a deliberate series of revivals, including Verdi masterpieces and four complete Ring cycles.

I find it hard to square what I know about composer Judith Weir with what happened last night. In one corner lies her 30-year output of songs, choral pieces and operas - as engaging and beguiling an oeuvre as that of any living composer's. I think of her waggish song cycle King Harald's Saga or her playful opera A Night at the Chinese Opera.

When blithe Susanna and not the expected Cherubino emerges from hiding before the astonished Countess and enraged Count, the latter instantly back-pedals on the fury he has been heaping upon his seemingly faithless wife. She rounds on him: “Crudele, più quella non sono!” (“Traitor, I am no longer her”) and everything suddenly stops. It's a tiny two-beat rest that usually goes for nothing except the signal for a key change, but here the moment is charged with drama. The Count shoots apologetic looks to cover his shame and the Countess painfully registers her lost trust.

Francesca Zambello’s production of Don Giovanni may only be 10 years old, but is already showing signs of decrepitude. Even back in its youth in 2002-3, this staging never had much of a spring in its step, but at least there were some fantastic casts to compensate. Bryn Terfel, Anna Netrebko, Simon Keenlyside and Erwin Schrott have all taken their turn here, but even with Gerald Finley returning in the title role there’s little the current incumbents can do to do rescue this aged and confused attempt at a seduction.

Imagine what John Cleese might have done with the tale of a slutty sleepwalker who finds herself staying at a packed provincial guest house? Bellini doesn't even touch on farce, let alone psychological investigation. He instead follows the archetypal bel canto formula: dramatic thinness and vocal display.

Whether or not we believe Wagner’s retrospective rebranding of the opera as a prototype music-drama, “a complete, unbroken web”, Der Fliegende Holländer reliably makes for a vivid evening’s entertainment. Which makes it all the more strange that this is only the work’s third outing at the Royal Opera in almost 20 years.

A legend on the operatic stage, Sir John Tomlinson (CBE) has sung with all the major British opera companies, made countless recordings, and for sixteen years was a fixture at Bayreuth, where he performed leading roles in each of Wagner's epic works. Throughout his career he has worked regularly with English National Opera and with The Royal Opera, Covent Garden, where in 2008 he created the title role in Harrison Birtwistle's The Minotaur.
