Some literature has had issues with BrokenBase since before fans were even called "fans".

----

* The ending of the ''Literature/HarryPotter'' series pretty much split the base in two, especially the epilogue, which was either an appropriate coda that closed the circle while showing that life would go on, or a piece of rubbish that shamelessly abused the clichés of the series and was the worst thing in all seven books.
** One of the key factors in this was the fandom, who are famously argumentative (particularly Harry/Hermione versus Ron/Hermione). That said, given the size of ''Literature/HarryPotter'' fandom, pretty much any strong opinion about ''any'' ships or characters could cause an argument in the wrong forum. Umbridge can at least be counted on to be universally hated, but the question of whether she was a Slytherin or a Hufflepuff still divides people.
** Also, some have actually accused Rowling of homophobia, given that of the LoadsAndLoadsOfCharacters, none was stated to be gay. Accordingly, the final scene of ''Half-Blood Prince'' was bashed for "pairing everyone up in neat little heterosexual rows". When she outed Dumbledore as gay, she was criticized for being too cowardly to put it in the books, though there was some arguable basis for that interpretation in the seventh book.
*** The outing created two very distinct camps - Dumbledore's Not Gay, She Made That Up to Make Herself Feel Better vs. It Was Obvious Or Maybe It Wasn't, But It Didn't Matter Then ('''Purple Velvet Suit''' people!)
** Which of the movies are AdaptationDecay and which are AdaptationDistillation? Well, it depends on who you ask.
** Are the books [[WhatDoYouMeanItsForKids for kids]] or [[WhatDoYouMeanItsNotForKids for teenagers/adults]]? And if you go by common knowledge (that the story "grows" with the original readers, so the earlier books are more kid-appropriate than the later ones), with which book do you draw the line? ''Azkaban''? ''Goblet''? ''Phoenix''? And should the movies/marketing cater to the new kid fans, or to the now-grown original fanbase? (Simply rating ''Goblet'' PG-13 caused a huge ruckus)
** The various tidbits of information J.K. Rowling has dispensed during various interviews before and after the publication of the last book has caused a rift in the ''Harry Potter'' fandom between fans who take those tidbits as the WordOfGod and those who say that if Rowling wants to make something official, she should write another book, because in their opinion, unless its published in a book, it's not official.
** One of the biggest broken bases of all. Reader's reactions to Snapes's last words to Harry "look at me" (with Lily's eyes) followed by the revelation of Snape's entire relationship with Lily and his reaction to her death. Depending on who you ask it's either a tragic, romantic TearJerker or deeply creepy and disturbing.
*** And related to this is whether you believe Snape was a KarmaHoudini or not. Some believe that his back story and sacrifice is penance enough whereas others think that the years of Hell he put Harry and the other students through is something that one sacrifice can not reverse to the point that you should be naming your kids after him.
* The fandom for ''Literature/ASeriesOfUnfortunateEvents'' has experienced some division over TheFilmOfTheBook, which condensed the plot of the first three books with a vague approximation of the AncientConspiracy material from later ones, and over the vague ending of the actual book series (some thought it was nicely in-keeping with the developing themes of unanswerable questions, others had hoped for some more tangible resolution).
* ''Literature/{{Animorphs}}'' fandom. The last book. Was [[spoiler: the BolivianArmyEnding]] a complete cop-out or a work of genius?
** There are also sharp divides over Cassie, turning her into TheScrappy in some parts of the fandom.
* ''Literature/TheLordOfTheRings'' and Tolkien fandom in general: {{The Movie}}s were either AdaptationDistillation or a pitiful case of AdaptationDecay.
** Not to mention the slash fandom v. non-slash fandom. All the pretty elves and men! vs. Tolkien would never have approved, and you are being untrue to the spirit of the books by slashing anyone! I'm pretty sure the two sides don't even ''talk'' to each other. They even have two huge completely separate fandom archives. [[http://www.storiesofarda.com/index.asp Stories of Arda]] is a family-friendly, strictly gen and het archive with stringent posting guidelines which explicitly declare the movies uncanonical. [[http://www.libraryofmoria.com/ The very not worksafe Library of Moria]] has only two guidelines - no het and no gen.
** And let's not overlook the Balrog wing debate.
** Tom Bombadil.
* ''Literature/{{Twilight}}'' has a nearly equal amount of Jacob/Bella and Edward/Bella fandom, causing massive ShipToShipCombat.
** The base seems to have split even wider with the release of ''Breaking Dawn''. The hardcore ''Twilight'' fans still say it's the best thing since smoked cheese, while others (including those who haven't just read the series for its GuiltyPleasures value) are still trying to repair the holes in their walls after reading through some of the bizarre and improbable plot twists.
** One could also argue that the largest split occurred when the series was popularized by the ''Twilight'' movie. It basically split avid readers (or people who had previously not heard of the series at all) into people who pretended to always hate it [[HypeBacklash because of how popular it made the books]], people who like the books but hate the movies, and people who have Edward Cullen bedspreads, with few neutral positions otherwise.
** The {{Hatedom}}, particularly the ones with the PassThePopcorn attitude towards the fans, ''can't wait'' until [[TheFilmOfTheBook the movie of]] ''Breaking Dawn'' comes out, purely so they can see what the fans do then.
* Since late 2004, ''Franchise/ThePhantomOfTheOpera'' fanbase has been divided into people who loved [[Film/ThePhantomOfTheOpera2004 the movie of the musical]] and people who despised it, with a side order of people who dislike the musical ''period'' and prefer to stick with the original novel.
** Matters worsened with the sequel to the musical, ''Theatre/LoveNeverDies''. There is absolutely ''no'' middle ground on that show and what it does to the established characters, and it doesn't help that the Really Useful Group seems determined to provide FlameBait whenever possible.
* The ''[[Literature/TheWheelOfTime Wheel of Time]]'' fanbase often argues over whether the series jumped the shark somewhere between Books 5 and 10, with die-hards claiming that the series never jumped at all whilst the majority seem to at least agree that Book 10 is absolutely horrendous. There is then the question of whether Book 11 successfully repaired the damage or was a case of too little, too late. Then are the fans divided over whether Brandon Sanderson finishing Book 12 after Robert Jordan's death is a good thing or not. There are also the fans who argue that Robert Jordan is a master of depicting male-female relationships, whilst others claim that all his couples, even the older ones, behave like 13-year-olds and loathe the relationships whilst praising the worldbuilding and magic system. There is also a group of fans who anxiously still want to know who killed Asmodean (a minor HeelFaceTurn villain killed by unidentified means at the end of Book 5), whilst other fans see it as a pointless mystery of no import that does nothing other than spark arguments. In short, ''Wheel of Time'' message boards are like minefields waiting to explode if you say the wrong thing at the wrong time.
** Not to mention the split between fantasy fans who hate TWOT with a firey passion and those defending it at LOTR's equivalent, or better.
** Solved. The epilogue of ''The Towers of Midnight'' specifically states that Graendal had 'Three Chosen, destroyed by her actions.' So assuming Mesaana and Aran'gar are killed by Graendal, the last Chosen to be killed would be Asmodean, since most of the Chosen are explicitly killed by either Rand or balefire.
* The ''Literature/AnitaBlake'' series fandom is fiercely split between fans of the earlier books who view much of what has transpired since book ten, ''Narcissus in Chains'', as little more than a series of sadomasochistic fanfics featuring similar characters to those present in the earlier books and the 'Troo' fans, many of whom started reading the series in the middle and loyally and often vigorously defend the literary skill of the author and the direction she has taken the series.
* The phrases "''Literature/WarriorCats'' fandom" and "majority opinion" simply aren't compatible. If you try asking which series is the best on a forum, you won't get the same answer from everybody. [[UnpleasableFanbase Some parts]] of the fandom think anything outside of the ''[[NostalgiaFilter Original Series]]'' is crap, but can't agree on what "sucks" more, or at which point everything started "sucking". This is divided even further by the fact that for ''both'' of most recent series people can't reach a consensus over whether the first three books sucked and the last three were great, or the first three were great and the last three sucked. ''Sunrise'' has also divided fans into a group who think it was a literary insult, and a group who think it was one of the greatest books in the entire series. Then there are the people who ''like'' all the books.
** It is simply ''physically impossible'' to find another person in the ''Literature/WarriorCats'' fandom who likes and dislikes the same characters as you. Don't even try. Almost all the main characters are prone to having several lovers and fandom, most notably being [[BaseBreaker Ashfur]], who has divided the fandom into people who believe his [[{{RoaringRampageOfRevenge}} attempts at revenge against Squirrelflight]] were completely unjustifiable and that he doesn't deserve an ounce of sympathy, and people who turn all his problems and losses UpToEleven and [[{{RonTheDeathEater}} believe that Squirrelflight was manipulating and trying to hurt him purposefully]]. A middle ground would be that while [[spoiler: an attempt at murder is always wrong]], the amount of emotional pain and trauma Ashfur felt from being rejected (especially since he had been under the impression that she loved him back right until she dumped him) should warrant sympathy and understanding for what he tried to do. But there, apparently, is no such thing as a middle ground.
** The author also enjoys writing spin-offs to give most of the villains sympathetic backstories. The only problem with this is several fans [[MisaimedFandom completely misinterpreting]] them and believing that the {{Big Bad}}s are genuinely good (see ''Rise of Scourge''). This causes disagreements between these fans, and the fans who [[EvilIsCool like them being evil]].
** Sol. He's got lots of people who love him, and lots of people who absolutely hate him (of course, Sol fans love Sol for the [[EvilIsCool same reasons]] [[ManipulativeBastard other people]] [[MagnificentBastard hate him]]).
** {{Shipping}}. It's like the series was written to create [[ShipToShipCombat shipping wars]]. There are no less than ''three'' characters with ''three'' canon pairings for each of them (Daisy doesn't count, because [[TheScrappy no one likes her]] and all shippings involving her have died by now).
*** One notable example was Lionblaze - Cinderheart, who he'd most recently had feelings for? Heathertail, who he was friends with as kits? Icecloud, a pairing that fans like?
** Old Names vs New Names. Do you think the old names are too plain? Do you think the new ones are too stupid?
** Ivypool and Dovewing. Apparently, if you love one of them, it is absolutely mandatory that you hate the other with a burning passion.
*** Although not to the same degree, there is a bit of this happening with other characters. For example, if you love Leafpool, you have to hate [[DieForOurShip Nightcloud]] (or vice versa). If you love [[TheChosenOne Firestar]], you have to hate Scourge (or vice versa). If you love [[BaseBreaker Ashfur]], you have to hate Squirrelflight (or you just hate Ashfur regardless of your character preferences).
** [[WordOfGod According to the author]], the series is written to avoid any straightforward answers in terms of [[GrayAndGrayMorality right or wrong]], leading to ''a lot'' of disagreements over most major characters. Discussing who is right and who is wrong can sometimes reach MindScrew levels.
** It sounds like you might say that it's almost like... ''[[StealthPun herding cats]].''
* For a period in the 1990s, when ''Series/DoctorWho'' had no new TV content to provoke fan infighting, a lot of fan arguments circulated around the Franchise/DoctorWhoExpandedUniverse book ranges and in particular the categories of 'trad' (books which attempted to mimic the old series as close as possible, just in book form) vs. 'rad' (books which attempted to tell stories 'deeper and broader than the small screen', to quote the tagline of one range of them). Since the new series came along and stole the Expanded Universe's thunder somewhat, these arguments have tended to die away.
** A related but distinct split was framed by Literature/DoctorWhoNewAdventures writer Gareth Roberts as "guns" vs "frocks"; "guns" are Serious Science Fiction, where the heroes have to use violence to win and the Doctor has to, at the very least, condone it and "frocks" are lighthearted stories where the Doctor saves the day by being clever and the villains are HoistByTheirOwnPetard. Sometimes "rad" and "gun" were considered synonymous (suggesting GrimDark stories the TV series couldn't possibly have done) as were "trad" and "frock" (Roberts's own "in the style of Season 17" books), but you could also have rad frocks (such as ''Sky Pirates!'', a joke book which casually suggests the Doctor is a HumanoidAbomination) and trad guns (such as ''Warmonger'', which deftly recreates the already fairly GrimDark feel of Season 22).
* George R. R. Martin: Has his constant postponing of ''The Winds of Winter'' and [[http://www.georgerrmartin.com/news.html endless secondary projects]] mean he's lost interest in [[ASongOfIceAndFire his own series]], or should his fans stop bitching and let him write his books at his own pace?
** There's also the split between those who think the post-''A Storm of Swords'' books are solid installments full of character development and setting the stage for the second half of the series, or meandering, padded messes that prove GRRM has bitten off more than he can chew.
* The ending of Trudi Canavan's ''Literature/BlackMagicianTrilogy'' has sharply divided fans, those who despise the ending being the most vocal. Many fanfiction pretend the ending never happened and discussions on pretty much anything regarding the series are prone to derail into angry author bashing.
* The ''Literature/{{Xanth}}'' fandom can be split pretty cleanly into two parts: Those who love the HurricaneOfPuns and keep coming back for more and those who gave up on the series because the puns practically took over the series. A good chunk of the latter cite the introduction of [[IncrediblyLamePun Ptero]] as the last straw.
* The ''Wicked'' fandom is more or less broken into three parts: The [[Literature/{{Wicked}} book fans]], the [[Theatre/{{Wicked}} musical fans]], and the ones that enjoy both. Within the musical fans there are the fans that are dedicated to one set of actresses, the most common being Idina and Kristin; there are even some fans who don't want to watch TheMovie if those two aren't cast as Elphaba and Glinda. The fandom as a whole is divided on whether the book, musical, or [[Literature/TheWonderfulWizardOfOz source material]] are the best.
** A big BaseBreaker is the shippings. The main one is Glinda/Elphaba (Gelphie) vs Fiyero/Elphaba (Fiyeraba); it helps that both shippings have WordOfGod and canon on their side in both the musical and book.
* The Literature/MaximumRide series. Oh, boy. When the fourth book came out, it divided the fanbase. Bring it up and it drives fans into an all-out war. Some really liked it, but others were driven completely up the wall at the plot shift from "bird kids running from MadScientists and wolf monsters" to "bird kids save the world from global warming".
* Kelley Armstrong's fandom is torn between ''Literature/TheOtherworld'' series and the ([[WhatDoYouMeanItsForKids barely]]) teen-friendly ''Literature/DarkestPowers'' spinoff.
* Fans of the CthulhuMythos are split between those who consider August Derleth's application of good-vs-evil themes to Lovecraft's amoral CosmicHorrorStory Verse to be sacrilege, and those who have no problem with it as long as it makes for a good story.
* The TomatoSurprise in the second book of the ''[[Literature/TheQueensThief Queen's Thief]]'' series caused something of a rift in the fandom: while many readers were provided with a new {{OTP}} to top all [=OTPs=], a fairly large percentage of fans were absolutely horrified and either dropped the series altogether or tried to justify it with AlternateCharacterInterpretation (which came with its own UnfortunateImplications).
* While the ''[[Literature/TheDresdenFiles Dresden Files]]'' novels have usually had a remarkably intact base for such a long running series, small splits have begun to appear since book 12, ''Changes.'' The series has lost some readers since then, Book 13, ''Ghost Story,'' increased the numbers, as did ''Cold Days,'' book 14. While many fans feel the series never lost it's trademark blend of humor, action and likable characters that made the series great, and eagerly await to see how the story develops now that it's taken a less predictable path, some feel the series has lost some appeal since the [[NothingIsTheSameAnymore shake up]] in the status quo in ''Changes''. Some fans say that the [[TookALevelInBadass levels in badass]] Harry has taken have taken him too far from his roots as a humble, crime solving wizard detective and turned him into a superhero always saving the world. There's also a feeling among some that series is suffering from ArcFatigue regarding the unfolding main story, and that the story is juggling so many plot threads and characters that proper focus has been taken away from all of them. The directions some characters have taken since [[spoiler: Harry's death]] have displeased some fans, and others have said that the books are suffering from ProtectionFromEditors, with an increasing number of descriptions and events that just slow the story down without contributing anything meaningful. Some fans now say the series ended with book 12.
** There's also a large debate as to whether the TV Show was a good Adaptation that simply had a few [[AdaptationDistillation understandable changes]], or a complete garbage that shared only a name with the novels.
* ''Literature/HisDarkMaterials'' caused a massive InternetBacklash, with a lot of criticism for the {{Anvilicious}} message and thinner plot.
* It seems like everyone in the YoungAdultLiterature fandom has an opinion on Creator/JohnGreen, and his use of the ManicPixieDreamGirl trope in particular. Some accuse him of [[StrictlyFormula using a clichéd formula for all his books]], while others maintain [[TropesAreNotBad his spin on the trope]] is original enough to avoid UnfortunateImplications and be interesting.
