Why Do Some TV Series Based On Books Skip Major Plotlines?

Cross-medium pollination is weird now. A book series gets popular, gets a TV show, the TV show changes things, and then those changes sometimes loop back into later book editions or the author's future writing. The adaptation stops being a one-way street and starts influencing the source material itself. It blurs the lines of canonical authority.

When a book writer expands on a TV series plotline, they often dive deeper into the characters' inner thoughts and backstories. In 'Game of Thrones', for instance, George R.R. Martin provides extensive details about the history of Westeros and the motivations of each character, which the TV series couldn’t fully explore due to time constraints. This allows readers to understand the complexities of the political intrigue and personal relationships in a way that the show only hints at. The books also introduce subplots and characters that were omitted in the TV adaptation, enriching the overall narrative and providing a more comprehensive experience for fans who want to delve deeper into the world.

I’ve noticed a few series that skillfully weave holy books into their narratives. 'Supernatural' stands out for its frequent references to biblical lore, especially with characters like angels and demons drawn from Christian theology. The show’s portrayal of apocalyptic themes and divine battles feels both epic and grounded. Another fascinating example is 'Good Omens', based on the novel by Neil Gaiman and Terry Pratchett, which humorously yet respectfully explores the Book of Revelation. The dynamic between the angel Aziraphale and the demon Crowley offers a fresh take on morality and destiny. For a more direct adaptation, 'The Bible' miniseries produced by History Channel brings key stories from the Old and New Testaments to life with dramatic flair. Each of these shows offers a unique lens through which to view sacred texts, making them engaging for both believers and curious viewers alike.

I’ve noticed that biblical stories often inspire compelling plotlines. One standout is 'Supernatural,' which weaves elements from the Book of Revelation, angels, and demons into its mythos, especially in later seasons. Another is 'Lucifer,' which reimagines the fallen angel’s story with a modern twist, blending crime procedural drama with theological themes. 'The Chosen' is a more direct adaptation, focusing on the life of Jesus and his disciples, offering a heartfelt portrayal of biblical events. For those who enjoy historical epics, 'The Bible' miniseries produced by Mark Burnett and Roma Downey covers key stories from Genesis to Revelation. 'Good Omens,' based on the novel by Neil Gaiman and Terry Pratchett, humorously explores the apocalypse with nods to biblical prophecy. Even anime like 'Saint Young Men' takes a lighthearted approach, depicting Jesus and Buddha living as roommates in modern Tokyo. These series showcase how timeless biblical narratives can be reinterpreted across genres.

Budget. It's almost always budget. That awesome fantasy battle or sci-fi world-building arc in the book? It would require an additional 50 million in CGI, three more months of shooting, and a dozen new sets. The studio looks at the schedule and the bottom line and says 'nope.' So the script gets rewritten, and a character-driven or location-heavy arc gets reduced to a line of dialogue or vanishes entirely. It's a brutal calculus where art loses to accounting.

Adaptations almost always trim the fat for TV, but the difference I notice isn't just about cutting subplots. It's in the texture. Reading 'Normal People' gave me Marianne's internal monologue, a constant stream of self-loathing that the show had to externalize through glances and silences. They pulled it off, but the emotional mechanism changed entirely. The book let me live inside her head; the show made me read her face. Sometimes that substitution works brilliantly, other times it flattens a character. I guess it's less about plot deviation and more about translation—some interior states just don't have a visual corollary. Honestly, most changes don't bother me if the spirit's intact. The 'His Dark Materials' series added whole new scenes for Mrs. Coulter, and it made her more terrifying, not less. The book had the luxury of Lyra's limited perspective; TV could show the monster in the shadows plotting. But then you get something like the later seasons of 'Game of Thrones', where departing from the books meant losing the intricate political logic that made the world feel real. The plot 'beats' might've been similar on paper, but the cause-and-effect got sloppy. It stopped feeling like a lived-in universe and started feeling like writers moving pieces on a board.

I’ve been combing through the sample chapters and fan theories for years, so here’s where I think we’re headed. The big one is the Meereenese knot—George R.R. Martin’s term for the narrative tangle in Slaver’s Bay. The last we saw, Barristan had just seized control in Meereen after Dany flew off on Drogon. Tyrion’s with the Second Sons, and Victarion Greyjoy is sailing in with his fleet and that horn. The continuation will be the battle of fire, for sure, resolving whether Dany’s forces can hold the city. Then there’s the aftermath: does she return? Does she head west? That’s the primary plot engine. Up in the North, the cliffhanger is Stannis at Winterfell, supposedly dead per the Pink Letter but almost certainly not. The continuation will be the fallout from his battle in the snow, the true fate of the Karstarks, and the huge reveal of what’s happening with the Boltons and the Freys inside. We’ve got Theon and Asha right there in the middle. Plus, Davos is off to Skagos to find Rickon, so that’s another thread that has to pick up. And don’t forget King’s Landing. Cersei’s just had her walk of shame and is out for blood, while the Tyrells are in a precarious spot with Margaery’s trial. That’s a powder keg waiting to blow. Meanwhile, over in Oldtown, Samwell is learning secrets at the Citadel while Euron Greyjoy threatens the Reach—that’s a major new front. And of course, Bran’s training with the Three-Eyed Crow, which will likely start revealing the deep history of the Others and the Long Night. It’s a lot of plates spinning, but the continuation is really about convergence, moving these scattered pieces closer together for the endgame. Honestly, after all this waiting, I’m less interested in the new shocks and more in how these established tensions finally snap. The sample chapter with Arianne heading to meet Aegon gives a taste of that—it’s all about momentum shifting back towards Westeros.

I've noticed that TV adaptations often cut out the internal monologues and thoughts of characters, which are a huge part of books. For example, in 'The Hunger Games,' Katniss's inner struggles and thoughts are glossed over in the movies, making her seem less complex. Descriptions of settings and minor characters also get trimmed to save time. In 'Game of Thrones,' many side plots and world-building details from 'A Song of Ice and Fire' were left out, simplifying the story. Flashbacks and backstories are often condensed or removed entirely, like in 'The Witcher,' where Geralt's past is less explored compared to the books. These cuts can make the adaptation feel rushed or shallow compared to the rich depth of the original material.

I can say that the ending of Frank Herbert’s original series (up to 'Chapterhouse: Dune') doesn’t neatly tie up every major plotline. Herbert’s vision was vast and philosophical, focusing more on themes like human evolution, power, and ecology than on conventional resolutions. The final books leave key questions open, especially about the fate of the Bene Gesserit, the Scattering, and the ultimate destiny of humanity. This ambiguity is intentional—Herbert wanted readers to ponder the bigger picture beyond individual characters. That said, the core arcs of Paul Atreides and Leto II reach profound, if tragic, conclusions. Leto’s Golden Path achieves its goal of ensuring humanity’s survival, but the aftermath is left exploratory. Brian Herbert and Kevin J. Anderson’s sequels attempt to provide closure, but purists argue they diverge from Frank’s nuanced style. The original ending feels like a pause in a grand, unfinished symphony, which is part of why 'Dune' remains so讨论-worthy.
