Natalia Osipova was better than I feared she might be given subdued reports of her debut in the role but not as good as I had (optimistically) hoped she might be: so she didn't pull off an O/O the equivalent of her extraordinary Bolshoi Giselle at the Royal Opera House. In summary, last night was a very commendable O/O but not one that engaged and moved me profoundly although it's been quite difficult for me to pinpoint why. I'm not an expert in technical specifics but I thought her dancing was very strong : balances, jumps, fouettes were all accomplished with ease. Some of her "swan" movements and gestures looked rather awkward as if she wasn't entirely at ease in the character. What was also lacking at times was a sense of the tragedy and vulnerability of Odile. It's not to say that pathos was absent but I felt she played Odile "big" particularly early on. (I realise that Odile and Kitri are roles which are deemed to play to her strengths but the vulnerable side of her Giselle was astonishing.) It will be interesting to see how her performance changes over her 3 shows since she was probably nervous last night: her partner and the RB production with all the mime are I think new to her. There was a HUGE roar for her at the curtain calls, so the audience certainly appreciated her. Carlos Acosta was remarkable for a man in the twilight of his career, noticeably better than he was a couple of years ago. Of course he doesn't quite have the energy of a young man but his warmth and elegance combined with his perfect partnering, wonderful elevation and great jumps made his performance a total pleasure to watch. The RB production itself is horribly dated and cluttered, but Clement Crisp in his FT review has made all those points for me.
