History YMMV / FateKaleidLinerPrismaIllya

* FandomSpecificPlot: There's a surprisingly high amount of fandom ideas where [[Videogame/FateGrandOrder the Fujimarus]] get similar powers to Illya and start collecting their own class cards. Strangely, it's ''male'' Ritsuka that is treated as the counterpart in these plots.

** Still others are [[DarknessInducedAudienceApathy simply tired]] of ''3rei's'' [[ToneShift considerably more serious tone]] regardless of the characters involved, which the Miyu arc has only [[DarkerAndEdgier exacerbated further]]. Previously, ''3rei'' had paced its more serious drama and action with a plentiful sprinkling of comedy and Fanservice in between, even showing [[spoiler:the Ainsworths']] ([[FauxAffablyEvil Faux]]) AffablyEvil side, and if pacing didn't allow for such breaks there were often [[BreatherEpisode purely comedic side-chapters]] to give the reader a break. In contrast, this story has seen CerebusSyndrome in full effect, being a nonstop TraumaCongaLine for [[spoiler:Shirou]] approaching levels of bleakness that wouldn't be out of place in ''[[VisualNovel/FateStayNight Heaven's Feel]]'' or ''LightNovel/FateZero'', and [[ShooOutTheClowns without a single side chapter and hardly any appearances by the regular cast to break the tension]]. You'd find it hard to believe the series started as a lighthearted love letter to the MagicalGirl genre. Thankfully, the flashback doesn't last ''too'' long, and [[spoiler:Shirou]] even [[LampshadeHanging lampshaded]] how long it was.

* SomeAnvilsNeedToBeDropped: The third episode of season 3 had Mimi becoming a YaoiFangirl, which weirds Ilya out. Suzuka's sister intervenes and tests Ilya by saying that if they can't reach an understanding, they might as well stop being friends. A guilty-feeling Ilya realizes that while she may not be into yaoi herself, that's no reason to break a friendship.

* ShipTease: Of the non-yuri variety, we have:
** Gilgamesh: it's hard not to see his teasing of Chloe and Illya as flirting. Double points when he does it toward Chloe when he is naked. This is morbidly hilarious considering his mainline relationships with their respective characters. Remember "the doctor" scene in UBW?
** Shirou: it be easier to list people who aren't teased with Shirou though the most subtle probably goes to Sella, with even her own sister and Shirou's mother basically trying to pimp her out to him. In the manga, Rin has the most ship tease; she has been the focus of many side chapters that focusing on her relationship with Shirou that no one else has had. Although one such chapter introduces this world's Sakura and gives Shirou a ship tease with her.
** [[spoiler:The Shirou from Miyu's world]]. He's been shipped with [[spoiler:Miyu in much the same way Illya is with Shirou, Sakura due to their shared past, and Angelica as shown under the FoeYay]].

* CrowningMusicOfAwesome: [=ChouCho=] brought her A-game with the opening theme, [[https://www.youtube.com/watch?v=OBp5XMc-eNA "starlog"]] and the insert song of Episode 9, [[https://www.youtube.com/watch?v=7CS3oZ889M4 "kagami"]].
** Episode 6: [[https://www.youtube.com/watch?v=jiRdixLq38o "Shoujo Shinka!"]] (a.k.a [[spoiler:'''EMIYA''']]) ''and'' [[https://www.youtube.com/watch?v=hGJSdgwtZw8 "Shoujo yo Kate"]] (a.k.a [[spoiler: '''SWORD OF PROMISED VICTORY''']]).

* HilariousInHindsight: The fact that Illya's series crossed over with ''Franchise/LyricalNanoha'', well-known for being a popular MagicalGirlWarrior spinoff of a visual novel, becomes this if you look at how they treated their source material's original players and families: while the ''Triangle Heart'' cast remained mundane and were eventually ignored after the series left Earth, the Einzberns and Emiyas almost met the same fate...[[spoiler:if it wasn't for them ''also'' getting actionized alternate universe counterparts that eclipsed their "originals" in popularity, with the sub-arc explaining it even functioning as a pseudo-spinoff of its own. Sadly, Miyu's Brother doesn't get a Magical Boy form to complete the circle.]]

* FoeYay: The pair of [[spoiler:Miyu!Shirou]] and [[spoiler:Angelica]] has become popular during their fight. The former has some [[ShippingGoggles ambiguously flirty]] dialogue along with directly calling her ''cute''. The latter seems to be continually trying to talk him down from fighting and seemed hesitant to kill him.

** Angelica, full goddamn stop. The fans are already clamoring for her when she first appeared with her awesome Gilgamesh Install, and her following appearances gave her plenty of time to shine, what with TheReveal about this series' background and her awesome fight vs. Kuro and [[spoiler:Miyu's brother]]. After her HeelFaceTurn, she's become even more popular as the fans jokingly said that she embodied "the perfect heroine for TYPE-MOON", with her combining traits of all three of ''Stay Night'''s heroines (blonde hair, MegaTwintails, [[BoobsOfSteel big boobs]],
stoic yet honorable nature, and older sister-like personality).

** [[spoiler: As of Chapter 48 of 3rei, it's become so blatant on Shirou's part that EveryoneCanSeeIt.]]
* GrowingTheBeard: It starts out as a fairly comedic series about Illya as a MagicalGirl. It then steadily becomes more serious. The CharacterDevelopment and ArtEvolution become more apparent in its second season, and the very notable increase of {{Fanservice}} and heavier action clearly show it's a {{Seinen}} series. This is especially apparent in [=3rei=].

** There's quite the large divide over how ''3rei'' was handled, especially over whether the arc's CerebusSyndrome an improvement or not. Also dips a bit into OldGuardVersusNewBlood after the release of the film covering Miyu's arc: those that got in for the drama and the situation surrounding [[spoiler:Miyu's brother]] complain about having to slog through two arcs' worth of magical girl antics and yuri ShipTease, while those who started from either the beginning or ''2wei'' complain about the sudden shift to [[spoiler: a mainline ''Fate''-esque storyline]] and having yet another magical girl series turn dark partways in, not to mention the ''sub''-arc where the titular heroine was not present.

* GrowingTheBeard: It starts out as a fairly comedic series about Illya as a MagicalGirl. It then steadily becomes more serious. The CharacterDevelopment and ArtEvolution become more apparent in its second season, and the gentle amounts of {{Fanservice}} and heavier action clearly show it's a {{Seinen}} series. This is especially apparent in [=3rei=].

* TheyWastedAPerfectlyGoodCharacter: Shirou. He goes from the primary lead of Fate/stay night to a disposable side character with no impact on the main plot. Shirou's lack of knowledge about magecraft and the Moonlight World, means he's limited to comedic antics. Even if they didn't focus on his mainline self's tragic circumstances or ChronicHeroSyndrome, the series could have at least had him as a support character a la [[Franchise/SailorMoon Tuxedo Mask]], helping Illya and friends from afar with his limited skills. Considering the deal with both Shirou and [[spoiler:Miyu's brother]], it's ironic that his role is more fit to have him called "Illya's brother" than by his actual name due to his sidelined status.

* BrokenBase: Illya's extremely bratty behavior towards [[spoiler:Kuro]] in ''Zwei'' turned quite a few fans against her, even those who didn't like [[spoiler:Kuro]] to begin with. Most of the fans her actions upset will point out that [[spoiler:Kuro]] wasn't really hurting anyone, and pretty much everyone except Illya seems to be okay with her presence, making Illya's frequent physical attacks DisproportionateRetribution ([[spoiler:especially since Kuro's curse means she ''can't fight back''). Fortunately, [[MyGodWhatHaveIDone she does get better]] after narrowly stopping Miyu and Kuro from fighting to the death, and the intervention of her mother also helps a lot]].

* TheyWastedAPerfectlyGoodCharacter: Shirou. He goes from the primary lead of Fate/stay night to a disposable side character with no impact on the main plot. Shirou's lack of knowledge about magecraft and the Moonlight World, means he's limited to comedic antics. Shirou further suffers from losing his drive to heroism to become a generic nice guy with no depth. The series could have played him as a Tuxedo Mask wannabe to go with the magical girl theme, helping Illya and friends from afar with his limited skills. Considering the prominance of [[spoiler:Miyu's brother]] its surprising they didn't do more with him

* BaseBreakingCharacter: Downplayed with [[spoiler:Miyu's brother]]. While general opinion is positive compared to [[spoiler: his counterparts in Illya's world and the original ''stay Night'' visual novel]], you'll find some folks saying he [[spoiler: merely upgraded from VanillaProtagonist to StockLightNovelHero]] given his circumstances.

* ArcFatigue: While nearly all fans agree that [[spoiler:Miyu's brother]] is indeed [[AlternateUniverseReedRichardsIsAwesome awesome]], some feel ''Drei's'' story arc exploring [[HowWeGotHere his and Miyu's backstory]] has overstayed its welcome. Having gone on for 10+ chapters with any final resolution at least several more chapters away, it's not hard to see why (by comparison, the entire original series ran for just 13 chapters). Making this even worse is the fact that the general details of the story are a ForegoneConclusion.

** The movie containing Miyu's flashback arc succeeded at gaining new fans of the series, thanks to him. [[spoiler:[[RescuedFromTheScrappyHeap They even consider Miyu's Shirou as]] ''[[RescuedFromTheScrappyHeap the best]]'' [[RescuedFromTheScrappyHeap Shirou portrayal in]] ''[[RescuedFromTheScrappyHeap any]]'' ''[[RescuedFromTheScrappyHeap Fate]]'' series.]]]]

** Even if some fans believe his arc has overstayed its welcome, it almost unanimously agreed that [[spoiler:Alternate Shirou Emiya]] is made of pure awesomeness. Some have gone as far as to claim him to be one of the best incarnations of the character, rivaling if not surpassing not only the likes of [[spoiler:UBW and Heaven's Feel Shirou]], but even [[spoiler:Archer!EMIYA]] himself. [[spoiler:The Shirou that was possessed by [[VideoGame/FateGrandOrder Sengo Muramasa]], however, might rival him in this department.]]

** The FoeYay between Rin and Luvia borders on BelligerentSexualTension. This is especially obvious in the manga, and in places like the special where Rin is made to be Luvia's {{Meido}}.

* TakeThatScrappy: In the third arc: for those who didn't like [[spoiler:Sakura's]] character in the Heaven's Feel route in ''stay Night'', Miyu's flashback nips that in the bud by [[spoiler:killing her Miyuverse counterpart off and using Miyu as a sweeter Sakura Analogue.]]
