Netflix's latest movie KPop Demon Hunters is an absolute must-watch for anyone who believes that music can keep demons at bay—literally. Directed by Maggie Kang and Chris Appelhans, the hilarious and heartfelt animated film blends ancient Korean mythology and modern-day K-pop, as it follows HUNTR/X, a kick-ass girl group who protects the world from soul-sucking demons through their gorgeous voices and the love of their fans.
