I really don’t think the appointment of ‘trendy’ Wayne McGregor will have any impact on attendances unless they lower prices for every new work he puts on. He certainly has his fans that support Random Dance and they will no doubt take themselves to the RB too – if they can afford to, but he is popular with the regular RB audience as well and I’ve discovered from asking around and reading comments on other dance forums that my ambivalence about his appointment puts me in a minority. The general consensus is that his acquisition is a brilliant move.
I agree with everything you said except the last two sentences.
It seems to me that Chroma was essentially two things, a marketing event and the creation of McGregor as a celebrity upon which the Royal Opera House Marketing Department will undoubtedly make and manipulate his status to satisfy the Arts Council and many individual Member of House of Commons, that think that a new and young audience will be attracted to the Royal Opera House by hid headline grabbing works. In fact there were very few young people present at the premiere rather it was late thirty year olds who were sold on 'heavy metal' music which 'White Stripes' were asociated with some decades ago.
The consensus you refer to is a small number of not very experienced or educated London critics and I am sorry to say people to whom ballet is an entertainment and a 'fan' (short for fanatic) event and not art event.
I have spoken to a good number of friends who like me have 40 plus years of attending RB performances, who not only disliked the Chroma in terms of unsuitability, but also thought that the patient(ie the RB) was still in the recovery stage in performing the classics and Ashton repertoire and not yet ready, for such an extreme activity as McGregor's dance work.
As the celebrity machine begins many critics, not all however, appear to want to become trendy 'celebrities' by association having written enthusiastically about Chroma. This is a similar desire of people who attend pop concerts.
