The Royal Ballet’s 2016 Frankenstein was a masterclass in how not to make narrative dance and the news that Liam Scarlett had been chosen to spring-clean and ‘reimagine’ Swan Lake had many balletomanes reaching for the smelling salts (it doesn’t take much, to be honest). It was sighs of relief and trebles all round when the new production premièred at Covent Garden last week: proper tutus; gorgeous designs; first-rate dancing.
