I feel like some of the negative reactions to Kimmie's win have been a little extreme.
For those who feel that Kimmie is completely amateurish and juniorish in her presentation, and therefore undeserving of high artistic scores . . . well, I can understand the point, but at the same time, I think it's not giving Kimmie enough credit. I would almost argue that rather than being overmarked at Worlds, perhaps she was slightly undermarked before.
There are actually a lot of great presentation aspects to Kimmie's skating:
1. Her choreography is quite good and compares favorably with that of many older skaters, such as Sokolova and Liashenko.
2. Her speed and flow across the ice are very good. I saw her skate live this year and was very impressed with this aspect of her skating. She really just flew across the ice. She has more speed and flow than many older, better-known skaters.
3. The quality of her posture and body line is definitely nowhere near Sasha's or Michelle's. But she still, overall, has quite good posture and line. Again, she really compares favorably here with many older skaters, such as Slutskaya, Sokolova, or even Kostner or Suguri. Irina is not at all known for her elegance of line or posture; neither is Sokolova.
To me, Kimmie's biggest presentation weakness is in the performance component. She doesn't yet have the musicality, phrasing, and audience rapport that older, more polished skaters such as Michelle and Sasha do.
But I do think when you look at the overall package of Kimmie's presentation, there's a lot to appreciate. Although she's young, I find her performances aesthestically pleasing and enjoyable to watch.
I personally was very happy to see her win. I feel like she's a much-needed breath of fresh air in ladies' skating. She is a great skater and seems like a nice young woman as well. Her youthful enthusiasm makes her a lot of fun.
