Safir, Claude. “'A Modern Cinderella'” by Louisa May Alcott: Subverting the Original Folktale.” https://www.academia.edu/9727489/A_Modern_Cinderella

"Alcott’s rewriting of Cinderella is a form of parody. By acknowledging the reader’s expectations and knowledge of the original Perrault's tale she is able to subvert a number of stereotypes and/or to attribute a value to what otherwise would be taken for granted. The revision of folktales is a common practice among women writers."

“In contrast to the Disney makes the step-sisters extremely ugly and dumb. They are dominated by Cinderella’s stepmother, who is given a demonic dimension compared to a happy, chubby fairy godmother” (Haase, vol. 1, p 203).
