It's not a particularly thoughtful or informed review
I give her credit for trying, but I don’t think a good editor needs to know dance to flag phrases like the one Ray copied, or like “performing swirling arm movements,” as amateurish. And what about “Diamonds, emeralds, and rubies, like a company marking 50 years, are rare and majestic, worthy of celebration. But this one was a little low-key.” Never mind that 50 years doesn’t necessarily make something rare and majestic. I lack the grammatical knowledge to say why “celebration” needs to be “a celebration” to make “one” correct in the next sentence, but the mistake grates nonetheless.
Criticism in Chicago newspapers fed my love of the arts in the 70’s and 80’s. I feel sorry for people who read this stuff instead.
