I'm not sure why. I haven't watched the show.
My favorite one is when Rue says to Cassie: “Wait, I don’t understand. If you’re not auditioning for Oklahoma, then why do you look like that?”
It's a show about high schoolers. But these high schoolers were obviously not homeschooled. No one looked like that at homeschool high school.
A show about homeschool high school would be very boring. No one (I know) did drugs or had sex or dated or did really anything interesting except cry over their Saxon Algebra textbooks.
