A true, unpretentious story about the real world, and a narcissistic self-pitying girl that lives in it, and wants her family to feel sorry for her until she gets what she wants in life (dollar signs and power). She gets all the haters out of her way and the world becomes her world, where nobody else matters. Nevermind anybody else's dreams or whose dreams she destroyed to get where she got, or what lies about herself and others she told people to get there, as long as she got there at any cost to everyone else is all that matters, since in Cinderella land, winning is everything and nothing is sacred.
Cinderella isn't full of shit or cartoonish to most people that know her, no, she's the one they wish they could be just like. They're just jealous of her Cartmanish awesomeness.
