Honestly, other than one really stupid judge (and everyone has those--only -2 for Satoko's pretty-much-a-fall, for instance, while everyone else gave -3), I don't feel Liza is overscored
compared to her competitors. Overscored/inflated compared to past programs, definitely, but she received the appropriate -GOE for her mistakes, and even her well-landed jumps (solo lutz, solo 2A, 3S-2A) didn't receive any of the +3s she'd usually get.
I do think Ashley should've beaten Liza on the second mark, for the LP, since Ashley skated with more attack and fire. But considering Ashley own tight landings, her taking out her opening transition into her 2A, and her 11th place SP + skating out of the last group, I'm impressed the judges gave her what PCS they did.
Satoko had what was basically a fall (and people in the thread were complaining about
her being overscored before Lena and Liza skated...); she definitely deserves higher PCS than what she received, but she's in turn really lucky--in both programs--to only get a UR call on one jump. Elena just made too many errors, and they were more disruptive than Liza's. Gracie should've received good scores for SS, but she skated with zero expression. At least Liza really turned it up in the second half.
The placements--SP, LP, and overall--are all correct, imo. The only one who got short-changed was Rika. Considering she's the only one to go clean in both programs, with attack and speed, I think fourth would've been more fair. Maybe Polina, too, though she is still lacking in the second mark despite going clean.
It was a pretty disappointing competition. I don't think I'll watch any of these skates back, except Ashley's for the redemption factor. My take-away moment will be Liza and Lena cuddling in the second K&C.

Still, let's not forget that these girls have all delivered great skates over the year--Liza at Europeans, Lena at GPF, Ashley at Nationals, Satoko at Nationals, ect.--and what happened at Worlds does not erase those skates.
Congratulations to Liza, the 2015 World Champion!

Congratulations to Lena for hanging on for a medal, and Satoko for winning a surprise silver! I'm saddened that Ashley once again misses the podium, but I think we'll see her next year, and I still believe she's got that medal-winning performance in her. So crushed for Anna... I hope she is okay, both physically and mentally.
