This document compares and contrasts the children's book series Animorphs from the 1990s and Twilight from the 2000s. [1] Animorphs targeted pre-teen boys with themes of saving the world from an alien invasion, while Twilight targeted young girls with themes of love and relationships. [2] The document argues that Twilight included more adult themes like vampires, love, sex, and teen pregnancy that may not be appropriate for its target audience. [3] It questions whether exposing children to media with adult themes can negatively impact their innocence and interest in age-appropriate content.
