How do simple things get complicated? How do they stay simple once they are complicated? These might, perhaps, be the questions from which choreographer Anne Teresa de Keersmaeker, starts. But in fact, she starts, as all great choreographers do, with the music. “Music is always my first partner,” she once said. And in Fase: Four Movements to the Music of Steve Reich, three linked duets and one solo, there are indeed three people on stage: de Keersmaeker herself, the wonderful Tale Dolven, and Steve Reich, absent but ever present.

Reports of ballet’s death are greatly exaggerated, but I’m not equally sanguine about the craft of choreography. Having sat dumbstruck through the four limping dogs masquerading as finalists in The Place’s prize “for dance” [sic] on Tuesday, I found myself amazed, simply amazed, all over again at the fecundity and sheer knowledge of Ashton’s Cinderella, having its umpteenth revival last night at the Royal Ballet.

Photography is linked closely with memory. Photographs help us recall family, friends, holidays, and it can attest to an event. But one could argue that it actually serves a purpose of forgetting. As we are immersed in a digital age, the photograph becomes a series of binary numbers which doesn’t exist until it is written or printed, and which can be erased as easily as it is captured. Photographs are now as close to human recall as technology will allow. Daniel Linehan's Montage for Three last night was a perfomance piece which tried to address that.

Birmingham is the fount of beauty and magic when it comes to ballet design. Covent Garden - forget it, too much money, too little taste. What illustrates that truism is the comparison that can be made between the Royal Ballet’s cartoony Cinderella production returning to WC2 next week and the magical visual experience that is John Macfarlane’s vision for Birmingham Royal Ballet’s new Cinderella, having its London premiere at the Coliseum this week.

Well, if you’re going to headline yourself in the title of your show "the talent", you’d better have some: audiences aren’t forgiving. William Trevitt and Michael Nunn, ex-Royal Ballet dancers headlining their own company for the last decade, have a history of these pre-emptive strikes – an earlier show was called Critics’ Choice – and they also have a history of living up to them. Fortunately for all, The Talent does too.

Les Grands Ballets Classiques de Stoke Poges are a company waiting to happen for most of us, but for Les Ballets Trockadero de Monte Carlo a bitter rivalry must be endured - one of their ballerinas didn’t show up last night in High Wycombe, due to winging on a last-minute errand of mercy to the Stoke Poges mob. Fortunately Ida Nevaseyneva was available to totter in with her eternally moulting Dying Swan - and all suddenly became right with the world. The Trocks are an errand of mercy, to anyone who loves old ballet, anyone who loves smart comedy.

As everyone who has been watching Agony & Ecstasy: A Year with the English National Ballet on BBC Four now knows, Vadim Muntagirov, last night’s Prince Siegfried, and Daria Klimentová, his Odette/Odile, are the ultimate in ballet melodrama: one is a young dancer on the rise, the other reaching the end of a notable career. And both came together to produce a memorable Swan Lake in Derek Deane’s tasteful proscenium production.

There’s been so much expectation of The Most Incredible Thing with the Pet Shop Boys’ first score, and the choreographer Javier de Frutos’s notoriety, that it’s inevitable to be reporting that it isn’t the most incredible thing as a show. Medium-level fun, off-kilter, camp musical theatre, yes, with a lavish pop-crossover score, but I can’t see any death threats being levelled at the choreographer after this one (except possibly from some ballet critics). The Thought Police have expunged any mention of his previous scandalous creation, Eternal Damnation to Sancho and Sanchez, from all the publicity material, which is apt, considering the new piece is set in a Soviet-style dictatorship.

For those in the know, Sergei Polunin has been marked out as “the one to watch” from his schooldays. Since he won the Prix de Lausanne in 2006 and joined the Royal Ballet the following year, he has been “the next big thing”. Well, I’m here to tell you, after last night’s performance of Rhapsody, he is not the next big thing. He is the big thing now.

At the 11th hour (as we all know from the current telly series), English National Ballet has pulled a gorgeous plum out of its back catalogue that throws open vistas of what a ballet company should be: Serge Lifar’s sumptuous Suite en Blanc. Why this beauty, laced with the hot Spanish deliciousness of Eduard Lalo’s 1881 music, hasn’t been done for 35 years can presumably be put down to its sheer difficulty, because this is a ballet that bathes the eyes in lipsmackingly tricky, astronomically stylish choreography - stylish as only French classical ballet can be.
