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.

It’s a reasonable argument, I'd say, that it is only worth going out to see dance, or anything else, if it’s probably going to be better than telly or conversation with friends. And only if it’s also worth spending a couple of hours travel by train, say £30 to £40, tickets all told, plus a drink on the town. Something for the Arts Council to take on board when considering who to lash out £364,044 taxpayers’ annual subsidy on, no? Or too base a criterion?

Places, please, deliciousness, please. This is Delibes, a man whose music goes with delectable disbelief, and this is that zany thing, a Fifties nymph ballet, so let us sip hallucinogenic Arcadian cocktails and leave normality at the cloakroom. But the sheer prettiness of Léo Delibes's ballets (La Source, Coppélia, Sylvia) is too much for most dancemakers to digest. Even a choreographer so oozing charm as Frederick Ashton made no classic with his 1952 staging of Sylvia. Last night, given the bumbling performance by the Royal Ballet after a few years’ absence, it came over even more as a ballet best to have on iPod.

How do young modern choreographers engage with their audience? With references from the street - motion that the audience knows and recognises? With musical expressiveness? With the development of a technical style that has a language of its own? How about with an instinct, a yearning to entertain? Surely not!

Iphigenia is an abandoned child, almost murdered by her father, lost in bewilderment, captured and indoctrinated in an artificial existence. It hardly matters that her father was the legendary Greek hero Agamemnon, her mother the notorious Clytemnestra.

I’ll retain lifelong, life-changing memories of the joyous mysteries of Merce Cunningham’s dances, so it’s unimportant for me that Nearly Ninety, his final creation before his death last year, won’t be one of them. Naturally his company brought it like a memorial on their farewell world tour before the troupe closes down, but last night’s UK premiere of it at the Barbican felt both sketchy and cumbersome, overburdened with fussy set and effects, and underburdened with the usual vigour and unearthly certainty of his dance.

It’s pretty hard to describe a Forced Entertainment show. But let’s try anyway: imagine a stage full of crazy dancers, the men in black wigs, the women in white ones, prancing around, flinging their arms in the air, mistiming their high kicks, and then running frantically up and down the stage. The lighting slides from bright white to sick pink, and the music is pop tunes with Japanese lyrics. Welcome to a wonderful world of controlled zany exhilaration.
