Judith Mackrell: “As a critic I’ve long resigned myself to the idea that dance is a lowly member of the arts community. … But suddenly, dance has got noisy and visible, and everyone wants to be its best friend. … And when the carnival is over, I worry that serious dance faces a bleak future. In hard times, how many casual punters will pay to see dance in the theatre? How many councils will fund a dancer-in-residence rather than care for the elderly?”
