The chasm between the top-class ballet available to London-area ballet-goers and the low-grade stuff peddled in the regions is the field where the battle to save ballet’s soul is nightly won or lost. Nothing could be more dispiriting than to see the Russian State Ballet of Siberia’s Swan Lake in Oxford one night, and the Royal Ballet’s Giselle in London the next, knowing that for many unaware Brits without easy access to the capital, Birmingham or Edinburgh the phrase “Russian ballet” implies some shamanic edict of unchallenged natural superiority. Far from it.

Busy, busy, busy tends to have been the watchword of Rudolf Nureyev’s elaborate choreographies. Prokofiev, as the most direct of musical dramatists, demanded streamlining from Sergey Radlov’s complicated scenario in 1935, but Nureyev tends to have jammed extra plotlines back in with un-Shakespearean knobs on. Thank heavens Patricia Ruanne, his Juliet for the initial four-week run back in 1977, and his first Tybalt, Frédéric Jahn, have returned to work so hard on the staging's fiddly bits as to make most of this accomplished revival seem like easy storytelling.

I was taken to task by a commenter this year who told me I should go and review music, if I couldn't enjoy dance. Hm. One takes such things to heart, but it's humbug. While piling up memories over 25 years might mean that the noise in my memory is getting more and more obtrusive, that doesn't mean you can't suddenly find the corker one night that wipes the field clean and places a new memory there which will move your yardstick yet again.

It’s been a journey, an emotional rollercoaster, since 14 soap stars and sports personalities abandoned reality three months ago, donned a series of spandex and chiffon outfits and embarked upon the most important experience of their lives. They all gave it 110 per cent, took disappointment on the chin and came back fighting, and last night the three finalists battled it out for the ultimate prize – the Strictly Come Dancing 2010 glitterball trophy.

The lighting chief holds the success of a magical fairy-tale staging in his hands. Whatever the designer has done, however fantastical and virtuosic his visions, the lighting chief can ruin it. So it is with English National Ballet’s new Nutcracker, in which two gigantic miscalculations kill any of its old-fashioned atmosphere. Act One is hobbled by a gauze dropped over the front of the stage for half of it; Act Two is sabotaged by ultra-violet lighting like a morgue fridge in a horror movie.

What a stunning show Matthew Bourne has created in his Blitz-era Cinderella - truly a magical ride created from what was in its original 1997 form a pumpkin waiting to be transformed. This must be the most heartwarming and sophisticatedly rewarding Christmas show in London, filled with a huge love of the city and a moving homage to humanity in wartime.

Fairy-tale ballets are a bitch. We all grow a mental image of what is “right” when we are about five, and then woe betide anyone whose vision is different – because of course it isn’t different, it’s “wrong”. So David Bintley and his designer, John Macfarlane, are up against audiences chock-full of preconceived notions. And I’m happy to say, after BRB’s premiere of their new Christmas show last night, they passed my inner-five-year-old test with flying colours.

Christmas rolls around, and so does Cinderella, a welcome alternative to the seasonal dance-critic bah-humbug that is The Nutcracker. First, the good news. The good news is Marianela Nuñez. Always a lovely dancer, in Ashton she just glows. No one could be more suited than she to Ashton’s fiendishly difficult petite batterie, those tiny, beaten, viciously fast steps; no one could be more suited than she to Ashton’s light, bright jumps: with her sunny temperament and lovely punchy ballon Nuñez rises (literally) to the choreography’s demands.

If only such a bubble of foolish hype did not follow Wayne McGregor wherever he goes, such bloated talk of reinventing dance, injecting it with brains, and infusing it with new chemical sensitivities and practically supernatural powers, one would be able to look at what his contribution to theatre is more clearly. He is not the Heston Blumenthal of dance.

“Nice is different from good,” sings one of Stephen Sondheim’s characters. And mostly, it is different, “nice” rarely being “good”. Christopher Bruce, however, blows that theory right out of the water, because Hush, his 2006 piece which opens Rambert’s Sadler’s Wells season, is both good and nice. And that’s much more remarkable than it seems: attempting to find the beauty, the depth and the radiance of “good” has caused many great artists to stumble. That Bruce achieves his goals with such serenity and power seems little short of miraculous.
