Netflix’s The Eternaut has rapidly become one of 2025’s standout sci-fi series, captivating global audiences with its chilling tale of survival against a deadly, alien-induced snowfall. Adapted from Héctor G. Oesterheld’s seminal 1957 Argentine graphic novel El Eternauta, the show marries nostalgic 1950s science fiction with modern post-apocalyptic thrills, much in the vein of The Last of Us.
Directed by Bruno Stagnaro and featuring a haunting score by Federico Jusid, The Eternaut adaptation stars Ricardo Darín as Juan Salvo, whose fight for survival in Buenos Aires sets off a gripping saga of cosmic horror and human resilience.
Since its April 30, 2025 premiere, the series has topped Netflix charts in multiple territories, earning praise for its authentic performances, striking cinematography, and faithful yet fresh take on the original material. As fans scour IMDb for ratings, Rotten Tomatoes for reviews, and Reddit for theories, anticipation is already mounting for The Eternaut Season 2, green-lit to conclude this ambitious adaptation.
Originally serialized as a graphic novel in 1957, El Eternauta by writer Héctor G. Oesterheld and artist Francisco Solano López stands as a cornerstone of Latin American speculative fiction. Its narrative—an Argentine everyman witnessing a snow-like pathogen that brings death on contact—served as an allegory for political oppression under the backdrop of the 1950s Cold War era. Netflix’s adaptation preserves the novel’s core themes of solidarity, sacrifice, and resistance, while expanding on scientific concepts only hinted at in the source material.
Under the stewardship of showrunner Bruno Stagnaro, the series elevates the story with high-production visuals, blending panoramic shots of a frozen Buenos Aires with intimate character moments. Screenwriters chose an episodic format—six tightly paced episodes—instead of a single film to honor the novel’s serialized roots and allow for deeper character development.
The Eternaut series opens on a seemingly tranquil Buenos Aires, where Juan Salvo (Ricardo Darín) attempts to enjoy a casual game night with friends—only for a crimson-tinged snowstorm to descend, killing anyone it touches. As survivors don makeshift protective gear and bands together, they discover the snowfall is neither meteorological nor chemical, but extraterrestrial in origin.
What begins as a tense survival drama escalates into a full-blown alien invasion: insect-like creatures emerge, guided by an unseen intelligence that infiltrates human minds. Juan’s quest morphs from escaping the lethal environment to battling both external threats and internal paranoia. The season finale reveals that key allies—Juan’s daughter Clara and friend Lucas—may already be under alien manipulation, setting the stage for a broader cosmic conflict.
Ricardo Darín as Juan Salvo: The central protagonist whose blend of cunning and compassion anchors the series.
Oriana Cárdenas as Clara Salvo: Juan’s daughter, whose evolving role hints at deeper alien involvement.
Ariel Staltari as Lucas: Juan’s close friend, whose fate underscores the series’ themes of loyalty and mistrust.
Supporting Ensemble: Includes renowned Argentine actors like Valeria Bertuccelli and Érica Ribes, each bringing authenticity to their roles in a story rooted in Buenos Aires culture.
Behind the camera, cinematographer Gastón Girod creates a stark, desolate atmosphere, while Federico Jusid’s score weaves between ominous string motifs and period-appropriate melodies, reinforcing both the series’ nostalgic and futuristic tones.
Netflix released all six episodes of The Eternaut series globally on April 30, 2025. The show immediately garnered critical acclaim:
Rotten Tomatoes: 94% approval rating based on 17 critic reviews, with a 97% audience score.
Metacritic: Score of 72/100, indicating “generally favorable” reviews.
IMDb: Viewers praise its production quality and faithful adaptation, with the series sitting at an average user rating of 8.1/10 (as of May 2025).
Critics have lauded its balance of heart-pounding suspense and philosophical depth, noting how it stands apart from typical Hollywood blockbusters by preserving the political allegory of the original comic.
Barely weeks after its debut, Netflix officially renewed The Eternaut for Season 2, slated to comprise eight episodes that will “dig into a lot of sci-fi concepts” only touched upon in Season 1. According to producer Matías Mosteirin and Netflix Latin America’s Francisco “Paco” Ramos, the upcoming season aims to conclude the narrative faithfully, wrapping up the story in “a beautiful way” without spin-offs or franchise dilution.
While the release window for Season 2 remains unannounced, pre-production is underway, with writers exploring the psychological fallout of alien mind control and expanding on the series’ cultural and political subtext.
