Featuring according to Balagueró "terror, blood, aberrations and terribly bad people",[2] the fiction is based on H. P. Lovecraft's "The Dreams in the Witch House", transferring the story to a "dirty, modern city" setting in the outskirts of Madrid,[3][2] focusing on a cursed building in Villaverde Sur.[4] Go-go dancer Lucía, on the run with a stash of pills and hunted by mobsters, takes sanctuary in an apartment block with sister Rocío and niece Alba only to find out that malevolent supernatural forces are at play in the building.

Meagan Navarro of Bloody Disgusting rated the film 3½ stars as a "slick and breezy action-horror movie far more memorable for its gruesome high-octane thrills than its cosmic chills".[11]
Shelagh Rowan-Legg of ScreenAnarchy deemed the film "a highly enjoyable film with horror, crime, buckets of blood", "awesome crafty old ladies, a cute kid, and a kick-ass heroine".[18]
Raquel Hernández Luján of HobbyConsolas rated the film with 58 out of 100 points ("so-so"), highlighting Expósito's absolute commitment to her role and the solid production design as positive elements, while lamenting what little is left of the original story and the little amount of cosmic horror, also pointing out that the film could have benefited from taking itself less seriously.[19]
Ricardo Rosado of Fotogramas considered that the film, even if "replete with good intentions", struggles to find the right tone amid the pastiche story, also assessing that Expósito does her best, bearing the weight of the scenes. In contrast, the film struggles to find its audience.[20] Also reviewing for Fotogramas Desirée de Fez rated the film 4 out of 5 stars, highlighting the film's "tribute to the (many) women of horror cinema" as well as Ester Expósito as the best things about the film, otherwise deeming the film to be "frenetic and brutal", bringing together the hallmark of Balagueró's works: "the search for poisoned images that conceptually and formally enclose horror".[21]
Miguel Ángel Romero of Cinemanía rated the film 3½ out of 5 stars, considering it to be a "triumphant" return of Balagueró to his horror origins, flaunting his ability to turn suspense into fantasy and horror.[22]
