You see it differently re Liza and Christina. My preference is Christina with the way she's been skating overall this season so far including her performances at SA and TEB. She faltered a bit in the sp at TEB, but I still find Christina more engaging to watch than I do Liza. As I said, I feel more warmth from Christina than I do from Liza. That's my personal perception and preference, and it's subjective.
Okay, cool.
I characterized Liza's moves as "seemingly mature" because she's still very young and I don't buy the flirtiness. It's studied because she has no mature experience behind it, so it lacks depth and meaning for me.
I understand that you don't buy it--that's totally fine. But my point was that Liza's flirtatiousness matches the music. If it has no depth for you, fine, okay, but I'll stick with the point of view that Liza's moves reflect her music. Whether or not one likes it is up to them, but these are moves that one can logically see how they connect to the music.
The difference IMO between Christina and Liza (because they are both still young and have a lot more developing to do) is that Christina is not trying to flirt, she's only trying to express her inner joy and deep love for skating.
Again, are you referring to the SP or FS? In her FS, Christina is skating to Libertango. I agree with you that Christina is not trying to flirt, but IMO, in her FS, she desperately needs to flirt. It's a tango. She needs fire, she needs fierce movements, she needs flirtatiousness and sensuality, and none of that is there. See Kanako Murakami's FS for an example of a well-done tango FS.
I just prefer the Christina I am seeing this season over both Julia and Liza. As Sandra Bezic said at SA, Christina has a subtlety in her skating that is antithetical to "fire," so right now Christina may not be taken as seriously in the marks, plus the fact she hasn't shown this kind of skating prior to this season.
Again, I'm not arguing against your preference. Christina may have a subtle style (I think introverted is a better word), in which case, she should have never skated to Libertango, because it is not music that calls for subtlety.
