And since it is a performance, I can react to it as a spectator based on how it looks... and I think it looks busy and a little frenetic.
How she would dance at a milonga isn't really the issue. Nor is how she might feel to a leader when social dancing. I AM keeping in mind that it is a performance. I'm not saying "Oh that is so inapropriate for a social dance floor" or "They would never do that at a milonga in Argentina". I did comment that her ability to do the adornos as well as she does speaks volumes about her skill.
I'm saying it looks too busy and that the footwork, while for the most part is well executed, musical, and precise, it is distracting from the feeling of unity between the two of them, making it a performance for her alone rather than for a couple. As such, it LOST some of the potential entertainment value for me because I could have enjoyed watching it more if she'd toned it down a little.
However, I also pointed out that often the frame only contains legs and feet making it harder to judge the overall performance aspects.
It's a little like watching a skating routine with too many difficult jumps or moves... While it can be exciting, sometimes you are distracted from the overall quality and flow of the routine by worrying if the skater will fall. A little can go a long way, in both skating tricks and fancy footwork. In fact, it has more impact if it isn't constant.
