An inexperienced eye may not be able to identify the technical aspects, and their difficulty, but I would argue that they will still be able to acknowledge flawless execution of those techniques when they see it.
Here is a good illustration:
The explanation of the technical aspects of the performance are interesting, but do they really change our appreciation of the performance? I don't know. Technique has to serve a purpose.
As for the question of attracting audiences, and "educating" them, that is a really tough one, which applies to all art forms. We can be inspired by passionate reviewers. Perhaps at the end of the day it less about what they say (though of course it can be very interesting) and more about their ability to single out exceptional performances within the vast mediocrity that surrounds us! So at the end of the day, a good reviewer is one with good taste
It's the blend of technique and creativity that the novice might not appreciate. In recent years perfect technique been a given at the Royal Ballet (was not the case at all 20 years ago). We have 2nd rank dancers who can perform the most difficult principal roles with technical perfection. Just like perfect measurements doesn't necessarily make good hifi, nor does perfect technique made perfect dancers. Some superb dancers, live Zenaida Yanowski and Natalia Osipova, I just never connect with. We bumped into Osipova, one of the greatest dancers in the world, in a juice bar in Tel Aviv and had a chat (a bit ironic as she lives one street away). We've seen her dance many times. She brushed off the difficulties of different technique as if it was just A, B C. Which for a dancer of her stature it should be. Tonight we saw new dances by dancers we'd not seen before. One principal ballerina had a look of fear on her face every time she had to hold a position on pointe. Another principal almost got thrown in the orchestra pit, which would have been an act of mercy. Then we had Siphesihle November in a piece by a truly great choreographer, who was simply sensational. He was a street dancing black kid in South Africa, he's set to become one of the world's best.
Baryshnikov was a midget who compromised style for get height. it was his style. Below is a video of the current Royal Ballet male principals. The first, Matty Ball, is dancing the same Albrecht variation (the Petipa original choreography). He's about 6' tall and quite bulked up. His arm position if far more controlled and precise. To me Baryshnikov is showing off at the expense of the true sense of the ballet. Later on, Corrales and Muntagirov can leap more like Baryshnikov, Corrales is closer in style, Muntagirov has princely elegance. At the end, Marcelino Sambe, only about 5'7", is a favourite as the most expressive dancer, his best role for me is Mercutio in Romeo & Juliet. I've seen him dance Romeo, not for me, requiring a short Juliet, Francesca Hayward, arguably the best actress in the company. Others, like Riyoshi Hirano, a giant of a man (he was sitting behind us tonight), is different to Sambe in every respect.
As the Royal Ballet is my local dance company, and I've been watching it regularly for almost 40 years, I have experience and knowledge of who can do what and when it's good or bad. I don't need to read reviews. Since Clement Crisp died I've not bothered. I can differentiate the good, the bad and the ugly without outside assistance. If I were spending very large amounts of money on hifi, I wouldn't do so without acquiring a similar level of personal experience to be able to make informed decisions. I would make the reviewer redundant.
Of course the best critics could praise Baryshnikov as the greatest dancer ever and others could criticise his artistry. He was before my time, but perhaps his most famous successor at ABT was Roberto Bolle, who I saw dance several times, most recently 2 years ago at La Scala in Milan, in Onegin. He was a dancer who had it all and critics really were superfluous.
