Silo season 3 has cleverly rewritten one story element from the original books, which potentially makes it more realistic and immersive than the original story. Going into season 3, Apple TV's Silo has surprisingly taken quite a few creative risks and deviated significantly from the books. While it is still staying true to the essence of the source material, Silo season 3 has already introduced quite a few major book changes. One of the most controversial book changes in Silo season 3 revolves around Juliette's arc. Unlike her book counterpart, the Rebecca Ferguson character is experiencing memory loss after returning home to Silo 18. Since memory loss plots can often seem too cliché, many viewers have expressed their concerns surrounding Silo season 3's story direction. Not all book changes in Silo season 3 have been divisive though. With one minor book change surrounding the past timeline, the Apple TV sci-fi show has managed to elevate itself above the source material and makes its storyline seem far more aligned with real-world geopolitics. This makes its portrayal of international tensions and their consequences far more hard-hitting. Unlike The Books, Silo Season 3 Explicitly Portrays Tensions Between The US & Iran The past timeline in Silo season 3 unfolds over 300 years before the present. It walks through the events of the "Before Times" and suggests how a conflict between the US and Iran eventually led to the central post-apocalyptic event. While season 3's first few episodes have not fully explored the final implications of this conflict, it is interesting how the show explicitly names Iran. In Hugh Howey's original Silo books, the central geopolitical setup is significantly more vague. There is no prominent narrative in the books about a proxy war between the US and Iran. The show, in contrast, has revealed that, after an alleged radiological "dirty bomb" is set off in the United States, the US government blames Iran. In retaliation, the US sends fighter jets to bomb a hidden facility in the mountains of Turkmenistan. This is when the US pilots cross a strange, black cloud which makes their aircraft malfunction. Charlotte Keene, the sister of rising Democratic Congressman Daniel Keene, is the only pilot who manages to survive the mission but ends up with amnesia. So far, the Apple TV sci-fi show has not completely explored what kind of weapon was used to take down the US pilots in Iran. However, it seems evident that it will eventually serve as a trigger for the overarching apocalypse. The show's explicit portrayal of a conflict between the US and Iran makes it a lot more compelling than the books because it adds a layer of realism to its drama. The Book Change Anchors Silo In More Recognizable Geopolitics Rekha Garton/©Apple TV/Courtesy Everett Collection As tensions between the US and Iran escalate in Silo season 3's past timeline, it almost feels like the show drops viewers into a recent news headline. While its post-apocalyptic elements still feel wildly fictional, it is fascinating how the Apple TV show does not shy away from updating the original story's geopolitical context. Hugh Howey's original books do an incredible job of establishing the stakes and immersing readers into their mysteries. However, by drawing subtle parallels with real geopolitical tensions between Iran and the US, the show makes its portrayal of an out-of-control global tech arms race seem more grounded. Instead of merely coming off as a sci-fi thriller that explores the consequences of unchecked human ambition, the show is turning into a compelling political thriller. It gives a sense of immediacy to the original story and makes Apple TV's Silo hit a much closer to home by reflecting the anxieties and political tensions of the modern world. Silo 9/10 In a dystopian future, men and women reside in a vast underground silo governed by strict regulations, believed to shield them from the hazardous world above. The series delves into the complex social order within the silo and the mysteries surrounding their subterranean existence.
