Post-apocalyptic sci-fi stories are a common refrain in pop culture these days. They haven't quite reached an overwhelming fever pitch, but it does speak to a larger trend that some of the most popular narratives on TV at the moment include the likes of The Last of Us, Silo, Fallout, and others. It's not just that studios and streamers seem more willing to embrace this side of sci-fi, either; television audiences are flocking to them, and, by and large, they've all earned critical acclaim. There's also the underlying factor that many of them have been adapted from other media, whether that happens to be a book or even a video game. Amidst all of this is where Netflix's new sci-fi thriller, The Eternaut (El Eternauta), comes into play. Created and directed by showrunner Bruno Stagnaro, who co-writes alongside Ariel Stagnari, the series is adapted from the landmark 1957 graphic novel by writer Héctor G. Oesterheld and illustrator Francisco Solano Lopez. Even if you're not at all familiar with its source material, The Eternaut is a chilling apocalyptic tale that's more than capable of sweeping you up into its story, with an at-times trudging narrative that somehow knows exactly when to sprinkle in the right twist to keep you watching.
