City of Shadows

City of Shadows received mixed-to-positive reviews from critics, who largely characterized it as a competent, gritty Spanish procedural drama. Set against the backdrop of Barcelona and heavily featuring Antoni Gaudí's iconic architecture, the show drew comparisons to art-centric mystery thrillers while remaining rooted in familiar detective tropes.

Many reviewers praised the central cast's performances, particularly leads Isak Férriz and Verónica Echegui, alongside the series' character development and innovative use of local architectural landmarks. The opening dramatic murder at La Pedrera was highlighted as a striking hook for fans of international crime fiction.

However, several outlets criticized the show's narrative execution and pacing. Reviewers noted that the plot could feel overstuffed and slow to build, with some pointing out inconsistent visual storytelling and a lack of genuine tension needed to make it a standout thriller.
