Blending fantasy and mystery elements into a TV show isn’t always an easy task, but the series that pull it off are some of the most engaging on television. While magic and world-building automatically set the best of the fantasy genre apart, introducing an element of intrigue in the form of an overarching mystery, or even a crime component that the characters must investigate, successfully connects with viewers of all kinds. Whether the mystery is rooted in reality or is the fantasy element itself, it creates automatic tension and stakes for the audience and characters.
