Fair enough, LLLLutz, you feel that Caro has better interpretation and choreography than Alissa. I think that Alissa has very good interpretation skills (as good as Caro) and better musicality than Caro, and more accomplished spins. I agree with you that Caro's choreography for her programs this season slightly edges Alissa's choreography, but that doesn't mean they aren't fairly equal in their overall ability to perform choreo.
"Soppy" for you, may be "beautiful and lyrical" to others. In any case, both Alissa and Carolina need to step it up and perform their programs with a lot more confidence, charisma and take charge attitude.
If you are not sure what "artistry" means in figure skating, start by taking a look at clips of Janet Lynn, Toller Cranston, John Curry, Robin Cousins, Jeffrey Buttle, Stephane Lambiel, Michelle Kwan, Gordeeva/Grinkov, Matt Savoie, and Johnny Weir at their best. Then you might want to take a look at both of Dai Takahashi's and Jeremy Abbott's programs this season. If that doesn't help explain artistry for you, I'm not sure what will.
But the judges give their scores for the current choreograpy, not for the possible ability, right?
I do understand what artistry in FS means to me, and it's not Alissa's plastic smile and that irritating shoulder move...As well as soppy is soppy and not "beautiful and lyrical" for everyone but me- "Valse Triste" is "beautiful and lyrical", "La Vie En Rose" is soppy all the way, it's obvious it was made especially for the Worlds, to make the French public like the skater. I'm afraid it will have the opposite effect - the program is way too naive and such a sophisticated public wouls probably like more Shostakovich. I'm sure you know French didn't like Edit Piaf very much, her songs were way too primitive for The French public, and she gain her popularity in US, where people actually liked that kind of light, soppy music with some "French", and thus exotic, feeling to it .
