The Crystal Cuckoo Review: The Netflix limited series is directed by Laura Alvea and stars Catalina Sopelana, Álex García, Itziar Ituño, Iván Massagué, among others. The six-episode series runs for about 50 minutes each, based on the famous novel by Javier Castillo. El cuco de cristal is a mystery drama wherein a young resident’s life changes after receiving the heart of another man. What begins as a quest for answers becomes an uneasy trip through a town full of secrets and long-buried pain.
The Crystal Cuckoo Review
Speaking for myself, I expected nothing more than an ordinary crime and murder story, but The Crystal Cuckoo, with its emotional angle, got me hooked. It combines mystery with the personal struggle and the slow pacing at times, but still, the show tries to draw the audience into Clara’s inner world of the search for truth.
The Netflix series The Crystal Cuckoo follows Clara, a first-year medical resident, who receives a new heart after suffering a sudden heart attack. Shortly afterward, she becomes curious—and then desperate—to find out about the donor. Her search takes her to a somnolent Spanish town that seems placid on its surface but has a dark underlying history.
I was very much attracted by the basic premise because it appears to be real. Unlike many stories about organ recipients, The Crystal Cuckoo series does not suddenly turn into the supernatural. Clara does not see or get any magical hints. She goes after the real signs, real people and real evidence instead. That made her trip all the more credible, and I connected with her on a deeper level.
However, I definitely felt that the series took a very long time to build up the suspense. I was irritated by the slowness of the first two episodes and kept asking myself when finally some action would start. Luckily, from the middle episodes on, the tension increases and the plot started revealing some amazing secrets.
What I liked most in this Spanish series The Crystal Cuckoo, was how it brings up twists, which are not just shocking but also a bit dramatic, in a very good way. Some come in as unexpected drops, revolutionizing everything you thought you’d understood. Other ones are emotional, reminding us that the characters involved are not mere victims or suspects; they are broken people affected by the years of silence.

However, I also have to say that this show deals with very heavy themes—especially the crimes committed against women—that might turn off some viewers. The series does not show it in a really vulgar way, but the context of the crime is dark. This added a lot of gravity to the storyline for me, yet at the same time, there are some moments that were hard to bear emotionally.
When Clara continues her investigation, the first thing she actually sees is the connection between the donor family and the concealed disappearances in this town. I loved how the writers gradually connected her personal story to the tragedies in the town. That made it feel like a unified plot, not some separate stories running alongside each other.
Catalina Sopelana really nails the role of Clara. She’s fearful, confused, and determined in a very straightforward and natural way. And yet, time after time throughout the series, the focus is pulled away from her and onto other characters, notably Miguel, the investigator from the past. Miguel’s story is alluring, without a doubt; yet, sometimes it is invisible to the main character, Clara, who was supposed to be bearing the heaviest emotional load.
Frankly speaking, I would have liked Clara’s character to have been more foregrounded since her emotional arc was the whole reason I became invested in the story in the first place. Every time the plot really fell into the police investigation flashbacks, I got a little estranged from it. The cast of characters, aside from the main lead, is still pretty good, especially the actors playing Rafa and Gabriel. Their characters are the ones that create quite a lot of unpredictability since you can never really tell what their next move will be. Just by being there, they are already creating a sense of threat in the show.
Netflix’s The Crystal Cuckoo started to get really interesting only at the fourth episode, when the secrets were being revealed one after another. You still get shocked in many scenes even though you might have guessed a couple of things. The links between the disappeared persons, the donor’s family, and the local society are disclosed step by step in such a way that the audience’s curiosity is awakened time after time.
However, compared to all the tension leading to the conclusion, it was somewhat of a letdown. Sometimes I enjoy open endings, but this time I felt the last few minutes unfinished. It left me with more questions, and not in the good way. I did expect a more emphatic end from a mystery thriller.
Netflix The Crystal Cuckoo Review: Summing Up
In short, The Crystal Cuckoo is a very engaging Spanish thriller; it has an engaging plot, great acting, and a mystery that keeps the audience guessing, though it suffers from slow pacing and the ending should have been made more effective. The beautiful visuals and chilling atmosphere haunt viewers’ minds while keeping them hooked. However, this may not totally satisfy you if you prefer a fast-paced thriller with a certain end. To me, this was an interesting and unique show, though not without its flaws.
