Guillermo del Toro’s lovely dark fairy tale The Shape of Water features a romance between a human and an amphibious man, but certain other movies will also fulfill those looking for human-monster love stories. Well-reviewed and highly acclaimed, The Shape of Water is packed with all of Guillermo del Toro’s trademarks: touches of horror, fairytale elements, Gothic romance, a prosthetic-formed creature, and darkly lovely visuals. The Shape of Water won Best Picture at the 2018 Oscars, along with three other categories. Still, it’s the romance that people remember.
