Fairy tales don’t only belong to the domain of childhood. Their overt themes are threaded throughout hit TV series like “Game of Thrones” and “True Blood,” “Grimm” and “Once Upon a Time.” These stories survive, says Maria Tatar, by adapting across cultures and history. They are carriers of the plots we endlessly re-work in the narratives of our lives — helping us work through things like fear and hope. Hosted by Simplecast, an AdsWizz company.
