The Spanish crime series 'City of Shadows' is currently trending on Netflix, competing with top shows like 'Stranger Things' in the Netflix Top Ten. The series features a dark plot set around the Gaudí building Casa Milà, where a burned corpse is discovered, leading Inspector Milo Malart, who has been suspended, and his partner Rebeca Garrido to investigate. Despite its popularity, there are no official announcements about a second season, although the show's continued success in the Top Ten suggests strong viewer interest. The series is based on the novel 'El Verdugo de Gaudí' by Aro Sáinz de la Maza, which has expanded into a series of books, providing material for potential future seasons. Filming for the first season took about 13 months, with a possible release date for a second season in early 2027 if Netflix approves. The series is a dark thriller with a focus on conspiracy and past secrets, set in atmospheric Barcelona, but it relies on familiar clichés and offers moderate suspense. The main cast includes Isak Férriz and Verónica Echegui, though the latter has passed away in 2025. A new season would likely feature a new partner for Malart. Overall, 'City of Shadows' is a well-crafted atmospheric thriller with potential for continuation based on the existing book series and its popularity.
