I also attended the San Jose Stars on Ice show last night. Sadly, I don't have a different opinion on Gracie's performance. I've seen her live before, notably at 2013 Worlds and 2014 Nationals--where she was
amazing. She's not only a far cry from her peak condition, but there was at least one moment in her first solo act where it looked like she had forgotten the choreography. There were a couple of moments like that in the final group number as well. She did two double toeloops that were barely off the ice, and I can't believe I'm saying this, but Adam Rippon's layback spin was faster than hers. I think she was missing from the group number that opened the second act, which was weird because Jeremy/Adam/Ashley were there.
Karen Chen was outstanding. Her first number was energetic and delightful. It looked like she was going for a 3Lz combo, which she turned into a 3Lz/half-loop/2T? Did one double jump, but nailed 2A, and in her stunning Butterfly Lovers exhibition, she landed all three of her triples, including 3Lz, 3Lo, and one other that I can't remember. Her interpretation and performance were beautiful--I had a lump in my throat. Butterfly Lovers was my favorite performance of the night--an exhibition that would easily fit in to any world-class skating show anywhere.
Ashley Wagner gave excellent performances. She was committed, energetic, and knows how to perform to the audience. My date (who knows nothing about skating) really liked her "Handclap" exhibition...might have had something to do with her costume.

She landed 5 jumps in her Exogenesis exhibition (two triple flips, two axels, and a triple loop). I've seen her live a bunch of times, from way back in 2010 at All That Skate LA, where she was the least credentialed skater there, to 2013 Worlds & 2014 Nationals, and she's really grown a lot as a performer. She looks great and I would not at all be surprised to see her make her second Olympic team.
