Last year I raved about Birmingham Royal Ballet, their artistic drive, their freshness, their impeccable artistic eclecticism and, not least, their superb dancing. It was with such memories that I went to Sadler’s Wells last week, only to leave both programmes with reservations and mixed feelings. Neither programme stood out for being particularly well constructed; one, titled Opposites Attract, lacked contrast and shadings, while the other suffered from excessive stylistic idiosyncrasy.
