Like you said she’s young and immature. I thought the issue with her was the obvious special treatment she received and better dancers being cut before her. Veterans have been called out and cut for falling out of pirouettes. She got “ bless her heart.”
As for how much she was featured, the editors loved making her look ridiculous. I’m not sure that she should want that treatment again.
I found her to be spoiled and entitled. Other girls her age have been on the show and not had her obnoxious personality of pushing to the front, etc. Even that wouldn’t be quite so bad if she wasn’t, as you said, a mediocre dancer.
