‘Silo’ Season 4 Has One Major Book Story Left to Get Right

The final season of Apple TV‘s Silo has a lot to explain, but the apocalyptic drama has quite a bit of story to tell as well. The show is based on a trilogy of novels by Hugh Howey, and while it has taken some liberties in the adaptation process, it has stuck to the source material where it counted most so far — even in places where it may not have been convenient. Season 4 will be the show’s final test, and we’ll see if all the changes along the way have led us to the same conclusion as Howey’s books. We’ll also see if these characters are similar enough to support the story’s central romance, or if that will be the biggest dropped plot in the series.
