Reviewing for Cinemanía, Miguel Ángel Romero considered De la Iglesia's creation as an immersion in the Lovecraftian universe, and also noted an implicit reference to Nyarlathotep in the season finale. Romero praised Cosimo Fusco's chilling performance and the performances of Eduard Fernández and Manolo Solo in antagonist roles, also welcoming the referencial nature of De la Iglesia's work (inspired by the likes of Antonio Mercero, Ridley Scott and John Carpenter). Among the negative aspects to be improved Romero cited the "particularly calamitous CGI" featured in the last episodes and the disjointed plots.
