Lambiel has it. Hanyu has it, although he still has a ways to go in developing some aspects of his skating. He is a compelling performer, however. Curry had it. Browning has it. Takahashi has it. Yagudin had it, and still has it, despite not being able to perform up to the technical standards of his competitive career. Button, back in the day, had it. Patrick Chan, not so much, at least, not in my opinion. I realize many here don't agree with me about Patrick. That's fine.
I don't believe anyone suggested that figure skating should go back to the good old days, however they may define them. I do transcription work, and, yeah, it's a lot better now to be able to use my computer to download audio files and type a document. I wouldn't want to go back to the good old days because the modern way makes my life easier. Transcription does not have any performance component beyond technically doing my best to get everything typed up in the format provided with proper grammar, correct spellings, and so forth. Speed helps, too, but as long as I get the work turned in on time, no one cares about how fast I type a paragraph. No one cares whether my fingernails are filed or my hair is perfect while I'm typing.
Figure skating, however, is not transcription. I think far more than the technical elements go into making a "gold standard" skater. Yagudin's Man in the Iron Mask program is pretty cheesy, if you just look at the elements, especially as compared with what the men are required to do today. Yet, the program stands the test of time, largely because the whole is greater than the sum of its parts and because it was Yagudin skating it. He brought his charisma, presence, connection with the music and to the audience to that program and elevated it to something that people still watch and talk about. His 2002 Olympic performance of MITIM was not perfect, but it was exciting and memorable because of Yagudin. I don't think anyone else, even other skaters who have that "it" factor, could have performed that program the way Yagudin did and electrified an audience with it the way he did.
