She Just Lets Her Drown
In Darcey Bell’s original 2017 novel, Emily doesn’t directly kill her twin sister, Faith. Instead, Emily merely allows Faith to drown and doesn’t save her. While one could argue that this is just a technicality and Emily’s intention remained the same in both cases,the key difference lies in what Emily exercises agency to do.A Simple Favormovie makes Emily a bigger villain by making her go out of her way to drown Faith and kill her, rather than allowing Faith to die through willful inaction.
Oddly enough, though,Bell’s book also considers Emily’s actions to be unforgivable, while the movie tries to justify Emily’s actionsby suggesting that she had no other choice but to kill Faith. More broadly,A Simple Favormovie portrays Emily and Hope’s backstory quite differently from the novel, wherein they never set their childhood home on fire to kill their father, and their real names are Emily and Evelyn Nelson, not Hope and Faith McLanden. The movie thus embellishes the narrative a fair bit, which is standard practice forbook-to-movie adaptations.
