‘The Crystal Cuckoo’ (2025) Netflix Series Review - Squanders Its Potential

There is a good show lurking within The Crystal Cuckoo (El Cuco De Cristal), but it gets lost amidst a convoluted storyline that moves between past and present. This back-and-forth structure is supposed to generate mystery, though the best it does is create an illusion of suspense. That illusion, however, is not sustained by directors Laura Alvea and Juan Miguel del Castillo. They show no feeling for mood or atmosphere. They manage to derive some creepiness from a scene in which a woman, in the rain, approaches a car, but The Crystal Cuckoo is otherwise devoid of such moments. What it offers are glimpses that suggest how emotionally charged the series could have been in the hands of better filmmakers.

There is a mother whose son suffers from osteogenesis imperfecta. To make matters worse, her husband is almost always on duty and rarely at home. The Crystal Cuckoo could have been a domestic—or marital—study of a relationship under pressure. The wife, after all, talks about taking extra shifts to cover hospital bills, and the husband's professional obsessions lead to a scene where he fails to pick up an emergency call from home. The filmmakers, however, never let things get too messy. The stress registers on the characters' faces; it never explodes on the screen with vehemence. This is also because the show decides to juggle other threads that, alas, cancel out each other's emotional impact.

The Crystal Cuckoo is about a nurse named Clara (Catalina Sopelana) who, after receiving a heart transplant, tracks down the donor's family. It is about a man obsessed with finding his sister's killer. It is about a wife and mother who mourns the loss of her son and her husband. And it is about a man racked with guilt over his own ugly actions. What drains the energy from these threads is the show's decision to connect them with a series of missing-persons cases. Who is the kidnapper? Are the victims alive or dead? A character claims Marta's (Itziar Ituño) husband kidnapped a little girl, but he is long dead. And what about that necklace found on a burned corpse that also appears in a picture belonging to a girl who, according to her brother, was murdered?

Even as a mystery crime thriller, The Crystal Cuckoo might have succeeded had it delivered interesting, shocking revelations. Unfortunately, the answers leave you wondering, "That's it? This is what the series was building up to?" When the whole picture comes into focus, we are left with yet another crime thriller in which women end up as sexual assault victims. This narrative turn has now become banal. It feels like a shallow crutch these shows lean on for "grittiness." According to The Crystal Cuckoo, being an incel is somewhat hereditary (an uncle and his nephew are referred to as freaks by women), but this is a reductive explanation—a shortcut to creating a generic crime-thriller villain. The directors neither render this exposition convincing nor do they do anything substantial with the narrative threads. What we are left with, in the end, is a series that squanders its potential.

Final Score- [4/10]
