The police procedural Grimm aired on NBC between 2011 and 2017, presenting six seasons worth of terrifying monsters to marvel at. Every season of Grimm seemed to up the ante, bringing new demons and more powerful creatures designed to send shivers down spines. The series mixed crime drama with supernatural horror and fantasy, recalling popular TV shows like The X-Files and Supernatural. However, uniquely, Grimm is inspired by the Brothers Grimm and their Northern European fairy tales. These folk stories provided ample inspiration for Grimm’s varied and creative monsters.
