Pretty much everything. Her accent is hideous. She thinks she's funny. She shouldn't have made it her first year (weight). She never looked super lean. She definitely didn't belong at point. Jenna and Lacey (and others) outdanced her by a mile. I cringe every time she's on the screen.
Some competitive studios don't allow their elite dancers to do high school pom/cheer teams. The time commitment is too great and they want them focused on real dance technique, not high school performances.
