I thought the same at first, but now I think it will be magical if she just interprets the music differently at some moments.
Btw, it's ironic that lots of people on GS criticize Yuna for not showing enough emotion during her programs, that they are usually talking about her lack of facial expressions. A
Personally, I like a mixture of both facial and bodily movements. If you want to like her lack of facial expressions in this program, that's fine with me. But for me, it's not enough--whether she is Yuna or not.
TBH, I don't know what either of you guys are talking about. Yu-Na shows a range of facial expression in Adios Nonino, all reflective of the music. The camera view isn't always close enough to see the range, but it's certainly there in photos.
Same with Les Mis--I was baffled by people saying that she wasn't showing a lot of facial expression, because she was, at every single moment.
