The Shape of Water is a fantasy film, not a science fiction film. Yes, there are scientists who want to study the fantasy creature, but it's a magical fantasy creature who's worshiped as a God. It's fantasy. And Guillermo del Toro used the language of fairytales to tell the story. It's fantasy, plain and simple. A fantasy romance. Not science fiction. We have yet to have a movie solidly in the science fiction category win for Best Picture.
