Lowtherlore, I don't think that Mao's wish to be the 15-year-old jumping phenom again is that unusual. Michelle Kwan said almost exactly the same thing about herself at one point. I think it's natural to wish for simpler times, especially when the weight of the country's skating aspirations is on one's shoulders.
Though I respect your view, and the courtesy with which you present it, of course I disagree with your perception that Mao hasn't grown since her Nocturne program. I think what you're seeing is not stagnation but her consistency of "voice," her personal style.
I agree that she is currently burdened (I wouldn't say overwhelmed because I suspect it takes a lot more to overwhelm this lady) with the technical aspects of skating, but that's due to a conscious decision to rebuild her technique on a more solid structure. To me it's indicative of a strength, not a weakness. To me, Asada will always be a skater that makes me lose the sense of time passing when I watch her. I haven't lost that feeling about her. So I'm happy to stand behind her, cheer her on, and await future developments.
So nicely stated, Olympia!
