You know, as someone who found her comments somewhat angering, it really doesn't have anything to do with her. Her comments making fun of the original film and saying how little she valued it pushed my buttons. Why? Because, as Iger informed us, the modern Walt Disney Company exists to be in the IP "mining" business. Iger/Chapek's Walt Disney Company is possibly too risk averse, lacking in creativity, or too incompetent to create new stories. Fine. If they want to cynically continue to go on "mining" IP it's their right as the owners of the business. The only thing audiences expected in return was for The Walt Disney Company to treat the intellectual property with respect.
In a way, Zegler's flippant comments seemed to show Disney couldn't even bother to do that bare minimum. They couldn't be bothered to pretend that they respected the original artists who created the very thing they were about to cynically exploit. And it was not only the original artists that were being exploited, no, it was the legions of fans who had grown to love it.
If you're going to cynically do some IP "mining," I expect you to put in that minimum effort.
