The Shape of Water also reimagines the classic monster narrative. Traditionally, films like Creature from the Black Lagoon ended with the monster destroyed for daring to desire a human woman. Del Toro reverses this: the monster is saved, and the human heroine transforms, literally, into an aquatic being. In the film’s magical realist climax, Elisa’s scars become gills, and she finds her true home underwater. This ending celebrates difference rather than punishing it, proposing that love is the force capable of reshaping reality itself.

The film's score, composed by Alexandre Desplat, perfectly complements the on-screen action. The music is a beautiful blend of classic Hollywood and Mexican folk influences, adding to the film's enchanting atmosphere.

"The Shape of Water" received widespread critical acclaim, with many praising its original storytelling, stunning visuals, and memorable performances. The film won several awards, including the Academy Award for Best Picture and Best Director at the 90th Academy Awards.
