History BrokenBase / StarVsTheForcesOfEvil

* Mina Loveberry is a particularly divisive character, mainly from those who find her cuckoo crazy behavior to be endearing and relatable, or annoying and in your face . [[spoiler: She became more divisive in seasons 3-4, where she becomes a more threatening presence, and eventually the main villain, while still being cuckoo crazy. One side thinks this helps make her into much more of a threat while still being entertaining. The other side thinks that she's played for comedy too much to be seen as a serious threat. Her backstory, where she was inspired by Solaria, doesn't help matters.]]

* The GrandFinale "Cleaved" basically [[{{Pun}} cleaved]] the fan base in more ways than one. Some viewed it as a bold form of closure for the series, with elements like [[spoiler:the ghosts of the past Queens helping to destroy the magic and the merging of Earth and Mewni]] coming together to make great ending to the series. Others just found it to be a rushed, anticlimactic story that brought up too much FridgeHorror ([[spoiler:Star destroying all magic in the Multiverse ''explicitly'' killed all magical creatures, such as Hekapoo and Star's spells, while what we see of the MergedReality implies that if anyone somehow didn't die during the merge, they'll soon die thanks to CultureShock and/or Mina's continued anti-monster crusade]]) and had too many hanging plot threads to serve as a satisfying finale.

* On that note, Marco in Season 3 also gained many detractors due to how badly he handled everything following ''The Battle for Mewni'' by [[spoiler:not admitting to Star that he had feelings for her too when he had the chance, obsessing over Star and Mewni while ignoring everyone and everything on Earth, leading to Jackie breaking up with him, then being generally useless as Star's squire when he returned to Mewni.]]
* Queen Moon became one as Season 3 progressed, with the final episodes of season 4 only adding to it. Due in part to how controlling she was of Star, there are many complaints that she was a terrible queen who later comes to mis-blame Eclipsa for the problems she's faced in her life.[[note]]Being too blinded by prejudice against monsters, too stubborn to see how misguided it was, neglecting their problems, denying there being a problem like it's below her pay grade when Star calls her out on it, etc.[[/note]] On the other hand, some fans find her behavior understandable. Her DarkAndTroubledPast gives her a legitimate FreudianExcuse to distrust monsters[[note]]Her mother, Queen Comet, was assassinated by the Monster Leader's treacherous General, Toffee, in the midst of signing a Peace Treaty.[[/note]], and Moon can reasonably blame Eclipsa for some of the recent struggles she's had to deal with, even if much of it was accidental on the Queen of Darkness's part.

* Glossaryck ''in spades''. He's either a funny character who has a strangely compelling way of giving wisdom and helping others, or an annoying troll who's too unlikable due to how he almost ''never'' explains anything directly, and just expects others to follow what he says without being clear, all intentionally. His entries under UnintentionallyUnsympathetic don't help out.

** Marco's characterization in season three. Some believe Marco had TookALevelInJerkass or was constantly grabbing the JerkassBall,[[note]]His frustration at not really being a knight, his feud with the other squires, and him not telling Hekapoo about Star causing the portals just so he can keep working with her.[[/note]] and that his boredom with Earth came out of left field. Others believe Marco's characterization was a natural progression of the insecurities he's always displayed, and his need to prove himself was blinding him to the consequences. Many in the latter group felt that it wasn't Marco who grabbed the JerkassBall at all, but that the Mewni characters had a firm hold on it.[[note]]Marco had every reason to expect to be made a knight seeing as King River specifically promised to do so, and the fact that he gave Marco his meat blanket and pretended it was a cape and somehow expected that Marco would never come back is inexplicably stupid even for [[TheDitz River]]. The other squires acting as if Marco didn't earn his position was pretty dubious seeing as, unlike Marco, they were all missing in action during the fight against Ludo and Toffee.[[/note]]

* Star herself was arguably this since the beginning, but she cemented this status starting at the end of Season 2. While she still remains very popular in the fandom and her fans love her for being a brave, plucky, determined, and energetic female protagonist, some others find her to be a bratty, selfish, annoying, and irresponsible protagonist who never learns her lessons (or forgets them almost instantly) and they find her a very bad daughter to her mother, especially in "Face the Music" and "Starcrushed". The series finale had Team "Selfish Star" double down on this stance '''hard''', with many comparing her actions in that final episode to that of [[spoiler:Thanos in ''Film/AvengersInfinityWar'']].

* [[spoiler:Miss Heinous, aka Meteora, is in a ''really'' weird position. During her times as Miss Heinous, she was either a compelling villain who brought up interesting points on individuality, or an annoying strawman who tried and failed to be serious. After "Monster Bash", where she finds out that she's Eclipsa's daughter Meteora, things went in a different direction. Her much more monstrous personality, both figuratively and later on literally, was either understandable given that she was the rightful heir to the throne, or she's essentially just an overgrown child throwing a temper tantrum, and was little more than a one note bad guy.]] It's safe to say that there's no middle ground for her character.

* The breakup between Jackie and Marco. Some were happy with the breakup due to disliking the pairing, while others were disappointed/angered because [[TheyWastedAPerfectlyGoodPlot it could've had more focus before it ended]]. Of the total four episodes that showcase their relationship, only "Bon Bon the Birthday Clown" (where they get together) and "Sophomore Slump" (where they breakup) has their dynamic as the focus of the episode. [[note]]''Just Friends'' has Marco be the third wheel in a group outing, and ends with Star trying and failing to invoke IWantMyBelovedToBeHappy, while the romance half of ''Starcrushed'' also places its focus on Star's unrequited feelings for Marco.[[/note]] The previously-mentioned objection towards the separation between Earth and Mewni also plays a role in this, as many felt the reason the breakup happened so quickly was solely because the Earth setting was being phased out and Jackie was an "Earth" character who was deemed to have no role in the new all-Mewni setting. Jarco shippers, and just Jackie fans in general, found this particularly galling since other "Earth characters" would still have appearances in that season, either from dropping in and visiting Mewni themselves, or Marco going back to Earth on a quick visit. On the other hand, many fans found the actual breakup scene itself to be well-written and emotionally satisfying, even ones who wished it hadn't happened so quickly.
* Star and Tom getting back together proved heavily divisive. Due to the implication that their relationship was formerly toxic and abusive, and the fact that Tom himself was always a very divisive character, this was inevitable. One party was perfectly okay with Tom getting back with Star, citing Tom's CharacterDevelopment as evidence against the relationship becoming abusive again. Another party saw it as the show advocating getting back together with an abusive ex, and think no matter how much Tom attempted to change, he would revert to being an abuser (or just unwilling to forgive Tom even if he ''had'' changed for the rape-like implication of his previous attempt to bind Star's soul to his own against her will). A third party was willing to wait and see, having hope that Tom's CharacterDevelopment would hold and that he'd continue to improve as a character, but also being weary of what the writers would [[DerailingLoveInterests eventually have him do in order to justify Star inevitably leaving him again]]. A fourth party just hated the ship altogether due to it interfering with '''other''' ships that they preferred.[[note]]On the Star side, namely Starco, on the Tom side, namely Tomco.[[/note]] Regardless of stance, that the two of them got back together was widely seen as [[ShockingSwerve coming completely out of left field with zero setup]], as Star goes from hating him, to wanting to be friends, to dating him again in ''literally less than 5 minutes''.

** Interestingly enough, this went in the opposite direction in season 3, where she's less impulsive, more reasonable, and more willing to be there for others. The base is split in three camps: those who found her annoying but find this new version to be worse because it's boring, those who were open to the change but thought it wasn't handled well, and those who think this was a natural progression of her character. And this third camp is ''also'' split, with some viewing Star as still exhibiting the same character flaws she's had since the start despite any other growth, making the show's pushing her as having become a mature young woman to fall flat.

Those who think either of the former two think that she's become a major hypocrite whose talks of being more mature are all talk and no show due to still exhibiting the same character flaws she's had, but magnified.

* King River is either an annoying, TooDumbToLive father and king, or a genuinely funny character with plenty of moments to shine.

* The GrandFinale "Cleaved" had basically [[{{Pun}} cleaved]] the fan base in more ways than one. Some viewed it as a bold form of closure for the series, with elements like [[spoiler:the ghosts of the past Queens helping to destroy the magic and the merging of Earth and Mewni]] coming together to make great ending to the series. Others just found it to be a rushed, anticlimactic story that brought up too much FridgeHorror ([[spoiler:Star destroying all magic in the Multiverse ''explicitly'' killed all magical creatures, such as Hekapoo and Star's spells, while what we see of the [[MergedReality Reality Merge]] implies that if anyone somehow didn't die during the merge, they'll soon die thanks to CultureShock and/or Mina's continued anti-monster crusade]]) and had too many hanging plot threads to serve as a satisfying finale.

* Despite his popularity as a [[VileVillainSaccharineShow competent, serious and effective villain]], there are a handful of people who don't like Toffee. Some believe he's too serious and out of place for a show like ''Star vs.'', and/or consider him boring. Fans on both sides tend to agree that [[TheyWastedAPerfectlyGoodCharacter his full potential went unrealized]], however. Despite the fact that he [[spoiler:died in the otherwise superb ''The Battle for Mewni'' arc, most of his motivations for what he did were unclear in the show itself beyond the most basic level of {{revenge}}.]] Not helping matters was WordOfGod claiming he was [[WellIntentionedExtremist a morally complex character]] who [[VillainHasAPoint had a valid point in viewing magic as something to be destroyed]]. Something ''[[InformedAttribute not clearly expressed any time he was on-screen]]'', only vaguely implied with a situation he was in during a ''flashback''. At the same time, some fans were attracted to Toffee ''because'' of how mysterious he was, and feel like answering everything would lessen him. The fact that Toffee did come to have parts of his backstory explained in ''Literature/TheMagicBookOfSpells'' didn't help matters, with debates refueling again over why such information never made it into the show proper.

* There's a rift between those who [[FanPreferredCouple ship Star and Marco]] and those who prefer them as PlatonicLifePartners, with the latter feeling tired and bored about the typical cliché of "the two main characters of the opposite sex who eventually fall in love and become the OfficialCouple" while the former either disagree with that reasoning, or agree in principle but think that the show itself [[TropesAreTools executed the friends-to-lovers trope extremely well]], and that Star and Marco's chemistry more than compensates for that cliché.
* The breakup between Jackie and Marco. Some were happy with the breakup due to disliking the pairing, while others were disappointed/angered because [[TheyWastedAPerfectlyGoodPlot it could've had more focus before it ended]]. Of the total four episodes that showcase their relationship, only "Bon Bon the Birthday Clown" (where they get together) and "Sophomore Slump" (where they breakup) has their dynamic as the focus of the episode.

On the other hand, many fans found the actual breakup scene itself to be well-written and emotionally satisfying, even ones who wished it hadn't happened so quickly.

* Ludo [[HijackedByGanon being ousted from the spot of main villain by Toffee]] yet again in Season 2. Obviously, fans of Toffee were pleased he was back and affirming himself as the overall BigBad, but others felt that it rendered Ludo's [[TookALevelInBadass slow climb to an actual threat]] null and void, and painted him as existing solely to be [[HarmlessVillain a villain that does nothing]] and get hijacked by bigger threats. This was somewhat mitigated by Ludo being placed back in control of himself in order to pull off his actual slow-building invasion plan in ''The Battle for Mewni'', and mitigated even further at the end of said movie when [[spoiler:Ludo took revenge for the hijacking by being the one to actually ''kill'' Toffee.]]
* The CerebusSyndrome that the show began undergoing in Season 2. Some fans accepted it with open arms and saw the show's greater emphasis on plot and character development as a welcome addition. Others felt the show fumbled in trying to deliver a more intense, continuity heavy story, seeing it as something completely unnecessary, or even damaging, for what was initially just a fun comedy. This only got worse post-"Battle for Mewni", thanks to all the other issues listed on this page.

* Despite his popularity as a [[VileVillainSaccharineShow competent, serious and effective villain]], there are a handful of people who don't like Toffee.

* Jackie-Lynn Thomas became one big time after she and Marco finally [[RelationshipUpgrade became]] an OfficialCouple, which earned her [[DieForOurShip quite a lot of backlash from]] [[FanPreferredCouple Starco shippers]]. Much of this comes down to shipping, which is discussed in Romance Subplot down below, but it boils down to whether you find her personality compelling or boring. Season 3 made this worse, as her sole appearance in "Sophomore Slump" had her break up with Marco. Fans who liked her hated that she was written out before her character could be properly fleshed out to be more than "[[MellowFellow laidback]] but [[{{Adorkable}} secretly goofy]] skater girl", all so the Starco pairing could happen guilt-free. Meanwhile her haters liked it for the exact same reason. [[spoiler:And Starco ''still'' wouldn't happen until the show's penultimate episodes in the following season, as Star rekindled her relationship with Tom by this point]].
* Star herself became one by the end of Season 2. While she still remains very popular in the fandom and her fans love her for being a brave, plucky, determined, and energetic female protagonist, some others find her to be a bratty, selfish, and irresponsible protagonist who never learns her lessons (or forgets them almost instantly) and they find her a very bad daughter to her mother, especially in "Face the Music" and "Starcrushed". The series finale had this group double down on this stance '''hard''', with many comparing her actions in that final episode to [[spoiler:that of Thanos in ''Film/AvengersInfinityWar'']].

* The ShipTease. As detailed in RomanticPlotTumor, Season 3 teased numerous ships while also attempting to sink others: after she's forced to return to Mewni, Star tries to get over Marco and gets back with her ex-boyfriend Tom in the process. Meanwhile, Jackie breaks up with Marco, which gives him the freedom to go to Mewni. Marco then receives ShipTease with Kelly, who has broken up with Tad (for real this time)... in the exact same episode Marco finally acknowledges his feelings for Star. Star and Marco later end up sharing a kiss behind Tom's back. Oh, and somewhere in the middle of all this, Marco also ends up angering Hekapoo into stopping their adventures together.[[note]]If you're keeping track, that's Starco at anchor, Tomstar in turbulent waters, Kellco teased, Markapoo sunk, and Jarco sunk.[[/note]] Meanwhile, the final season had [[spoiler: Kellco at sail for three episodes before [[OffscreenBreakup sinking offscreen]], Tomstar eventually hitting an iceberg and sinking after several episodes showcased how rocky their relationship, and Starco finally leaving harbor and setting sail [[LateMinuteHookup in the final episodes]]]]. Some viewers were perfectly okay with all of this, and noting that teasing ships wasn't something new to the show. However, other felt that all the romantic melodrama was pointless and distracted from other aspects of the show, such as the ongoing MythArc concerning Eclipsa and the monsters, as well as the comedy. Considering that [[spoiler:Starco as the final pairing had been seen as a ForegoneConclusion in the fandom since season one]], this group feels that the romance subplot ended up being nothing more than a WillTheyOrWontThey with extra steps, also noting that while previous seasons might've had a ton of ship tease, they rarely had whole episodes devoted ''solely'' to it.

On the other hand, many fans found the actual breakup scene itself to be well-written and emotionally satisfying, even ones who wished it hadn't happened so quickly.

* Tom. While a lot of fans agree that he is a good character, the divide lies in whether or not one should judge him for manipulating Star. Half the fanbase points out that Tom was a terrible boyfriend to Star, with DomesticAbuse implied, and keeps trying to manipulate her. The other half points out that he's actively trying to change himself and manage his temper; in "Mr. Candle Cares", he finally got the message that [[spoiler:forcing Star to be with him wouldn't work, and that for better or for worse Marco's looking out for Star as a friend and thus will protect her.]] However, he became even more of a base-breaker when [[spoiler: he and Star got back together again]] in Season 3. Added to that, a number of fans feel he became a wasted presence as a result, considering a lot of episodes in that season have him do nothing but passively react to most situations. Season 4 has him as a more active character, but that mixed with the show's romance subplot had some fans lament that regardless of everything, he's been forced into the role of ShipperOnDeck for [[spoiler:his girlfriend and his best friend]].

* Star herself became one by the end of Season 2. While she still remains very popular in the fandom and her fans love her for being a brave, plucky, determined, and energetic female protagonist, some others find her to be a bratty, selfish, and irresponsible protagonist who never learns her lessons (or forgets them almost instantly) and they find her a very bad daughter to her mother, especially in "Face the Music" and "Starcrushed".
** Interestingly enough, this went in the opposite direction in season 3, where she's less impulsive, more reasonable, and more willing to be there for others. The base is split in three camps: those who thought she was annoying and not that interesting anymore, those who were open to the change but thought it wasn't handled well, and those who think this was a natural progression of her character.

* Queen Moon became one as Season 3 progressed. Due in part to how controlling she was of Star, with complaints that she was a terrible queen.[[note]]Being too blinded by prejudice against monsters, too stubborn to see how misguided it was, neglecting their problems, denying there being a problem like it's below her pay grade when Star calls her out on it, etc.[[/note]] On the other hand, some fans found her behavior was understandable. Her DarkAndTroubledPast gives her a legitimate FreudianExcuse to distrust monsters[[note]]Her mother, Queen Comet, was assassinated by the Monster Leader's treacherous General, Toffee, in the midst of signing a Peace Treaty.[[/note]], and Moon was implied to not be the first royal family member to hate monsters[[note]]If the Mewman's depiction of Eclipsa running off with a monster, brainwashing of [[spoiler:Meteora]], children's book for Mewnipendence Day, and implication that a former Mewman Royal Family Member ordered Mina Loveberry to make sure [[spoiler:Meteora]] does not come back to her nursery, are any indication.[[/note]], nor is the prejudice solely from her, but from the Magic High Commission as well.

* Glossaryck ''in spades''. He's either a funny character who has a strangely compelling way of giving wisdom and helping others, or an annoying troll who's too unlikable due to how he almost ''never'' does anything directly, and just expects others to follow what he says without being clear, all intentionally. His entries under UnintentionallyUnsympathetic don't help out.

* The GrandFinale "Cleaved" had basically [[{{Pun}} cleaved]] the fan base in more ways than one. Some viewed it as a bold form of closure for the series, with elements like [[spoiler:the ghosts of the past Queens, Janna's admission of friendship, and the merging of Earth and Mewni]] coming together to make great ending to the series. Others just found it to be a rushed, anticlimactic story that brought up too much FridgeHorror (from [[spoiler:Star destroying all magic in the Multiverse and the merging of dimensions explicitly and implicitly resulting in countless deaths, respectively]]) and had too many hanging plot threads to serve as a satisfying finale.

* "Toffee", the final episode of ''The Battle for Mewni''. For all the hype about Star facing off against the titular BigBad, [[spoiler: he dies rather quickly after getting resurrected, with Star blasting him while in her SuperMode and Ludo crushing the last remaining bits of him under a tower]]. Many fans were understandably disappointed how such a villain was wasted, with some going so far to claim he suffered from a last second bout of VillainDecay. Meanwhile other fans found the episode to be one of the best, if not ''the'' best episode of the series for various reasons, not limited to: [[spoiler:Ludo's character arc that began in "Ludo in the Wild" coming to a satisfying conclusion, Toffee maintaining a menacing presence throughout, Toffee's liquid form being suitably unnerving, the return of the Whispering Spell, Star and Marco finally reuniting and hugging, Star's achieving a GoldenSuperMode, and Toffee's defeat ultimately being a fitting result of [[HoistByHisOwnPetard his own hubris and characters exploiting some of the mistakes he himself made]], allowing for [[TheDogBitesBack his biggest victims, Star and Ludo]], to directly eliminate him themselves.]]

* The GrandFinale "Cleaved" had basically [[{{Pun}} cleaved]] the fan base in more ways than one, especially with [[spoiler:Star destroying all magic in the Multiverse, meaning that all the magical beings like her spells are dead.]] While some viewed it as a bold form of closure for the series, others just found it very anticlimactic, unresolved, and very unfulfilling for a finale.

* The breakup between [[GirlNextDoor Jackie]] and Marco in ''Sophomore Slump''. Some were happy with the breakup due to disliking the pairing, while others were disappointed/angered because [[TheyWastedAPerfectlyGoodPlot it could've had more focus before it ended]]. Of the total four episodes that showcase their relationship, only ''Bon Bon the Birthday Clown'' (where they get together) and ''Sophomore Slump'' (where they breakup) has their dynamic as the focus of the episode. [[note]]''Just Friends'' has Marco be the third wheel in a group outing, and ends with Star trying and failing to invoke IWantMyBelovedToBeHappy, while ''Starcrushed'' also places its focus on Star's unrequited feelings for Marco.[[/note]] The previously-mentioned objection towards the separation between Earth and Mewni also played a role in this, as many felt the reason the breakup happened so quickly was solely because the Earth setting was being phased out and Jackie was an "Earth" character who was deemed to have no role in the new all-Mewni setting. Jarco shippers, and just Jackie fans in general, found this particularly galling since ''other'' "Earth characters" still got to drop in and visit Mewni just fine. On the other hand, many fans found the actual breakup scene itself to be well-written and emotionally satisfying, even ones who wished it hadn't happened so quickly.
* Star and Tom getting back together proved heavily divisive. Due to the implication that their relationship was formerly toxic and abusive and the fact that Tom himself was always a very divisive character, this was inevitable. One party was perfectly okay with Tom getting back with Star, citing Tom's CharacterDevelopment as evidence against the relationship becoming abusive again. Another party saw it as the show advocating getting back together with an abusive ex, and think no matter how much Tom attempted to change, he would revert to being an abuser (or just unwilling to forgive Tom even if he ''had'' changed for the rape-like implication of his previous attempt to bind Star's soul to his own against her will). A third party was willing to wait and see, having hope that Tom's CharacterDevelopment would hold but also being weary in the event something did happen. A fourth party just hated the ship altogether due to it interfering with '''other''' ships that they preferred.[[note]]On the Star side, namely Starco, on the Tom side, namely Tomco.[[/note]] Among all the groups opposed to the ship, it was widely seen as [[ShockingSwerve coming completely out of left field with zero setup]] (Star goes from hating Tom to wanting him to be just a friend to being willing to go on a date with him in the space of ''literally less than 5 minutes''), in sharp contrast to how Marco's relationship with Jackie and Star's feelings for Marco were both built up gradually over an entire season.
** The fact that [[spoiler:Star and Marco's first kiss happened while she was still dating Tom]] was immediately controversial, even if it did happen under duress. On one hand, there were a fans who felt that [[spoiler:the kiss was forced and that Marco looked like a jerk for making Star "cheat" on Tom. However, others pointed out that he had good intentions since the two of them wouldn't have been able to leave the photo booth (or at least, genuinely thought they couldn't) unless such action was taken. It was also pointed out that Tom had done worse things to Star and probably [[NotSoDifferent wouldn't have been much different]], along with Star being very much aware that she was still with Tom during her moment of shock afterwards. [[TakeAThirdOption There's also a third group of people -specifically the more diehard Starco shippers-]] that didn't care about any of the above as long as the two finally got to kiss]].

* The breakup between [[GirlNextDoor Jackie]] and Marco in ''Sophomore Slump''. Some were happy with the breakup due to disliking the pairing, while others were disappointed/angered because [[TheyWastedAPerfectlyGoodPlot it could've had more focus before it ended]], as only three episodes prior to the break-up showcased their relationship. And of those three episodes, only ''Bon Bon the Birthday Clown'' (where they get together) puts any focus on the couple. [[note]]''Just Friends'' has Marco be the third wheel in a group outing, and ends with Star trying and failing to invoke IWantMyBelovedToBeHappy, while ''Starcrushed'' also places its focus on Star's unrequited feelings for Marco.[[/note]] The previously-mentioned objection towards the separation between Earth and Mewni also played a role in this, as many felt the reason the breakup happened so quickly was solely because the Earth setting was being phased out and Jackie was an "Earth" character who was deemed to have no role in the new all-Mewni setting.

* The ShipTease. As detailed in RomanticPlotTumor, Season 3 teased numerous ships while also attempting to sink others: Star tries to get over Marco and gets back with Tom. Jackie breaks up with Marco and he develops an unrequited crush on Star. Marco then receives ShipTease with Kelly... in the exact same episode he finally acknowledges his feelings for Star. Star and Marco end up sharing a kiss behind Tom's back. Oh, andhe also ends up angering Hekapoo into stopping their adventures together between all of this.[[note]]If you're keeping track, that's Starco at anchor, Tomstar in turbulent waters, Kellco teased, Markapoo sunk, and Jarco sunk.[[/note]] Meanwhile, the final season had [[spoiler: Kellco at sail for three episodes before [[OffscreenBreakup sinking offscreen]], Tomstar eventually hitting an iceberg and sinking, and Starco finally leaving harbor and setting sail [[LateMinuteHookup in the final episodes]]]]. Some viewers were perfectly okay with all of this, and noting that teasing ships wasn't something new to the show. Others however, felt that all the romantic melodrama was pointless and distracted from other aspects such as the lore and comedy, considering that [[spoiler:Starco as the final pairing had been seen as a ForegoneConclusion in the fandom since season one]]. This group also notes that while previous seasons might've had a ton of ship tease, they rarely had whole episodes devoted ''solely'' to it.

* Ludo [[spoiler:[[HijackedByGanon being ousted from the spot of main villain by Toffee]] yet again]] in Season 2. Obviously, [[spoiler:fans of Toffee were pleased he was back and affirming himself as the overall BigBad]], but others felt that [[spoiler:it rendered Ludo's [[TookALevelInBadass slow climb to an actual threat]] null and void, and painted him as existing solely to be [[HarmlessVillain a villain that does nothing]] and get hijacked by bigger threats]]. [[spoiler:This was somewhat mitigated by Ludo being placed back in control of himself in order to pull off his actual slow-building invasion plan in ''The Battle for Mewni'', and mitigated even further at the end of said movie when Ludo took revenge for the hijacking by being the one to actually ''kill'' Toffee.]]
* The CerebusSyndrome that the show began undergoing in Season 2. Some fans accepted it with open arms and saw the show's greater emphasis on plot and character development as a welcome addition. Others felt the show fumbled in trying to deliver a more intense, continuity heavy story, seeing it as something completely unnecessary, or even damaging, for what was initially just a fun comedy. This only got worse post-"Battle for Mewni", thanks to all the other issues listed on this page.

* While a lot of fans liked the early reveal that the Mewmans were the invaders, and the monsters were the victims of colonialism, some were divided on the lengths the show had gone with it since, feeling it became {{Anvilicious}} in its messaging as time went on.

* "Toffee", the final episode of ''The Battle for Mewni'', was considered a letdown for some though it lived up to the hype for a lot of other fans. For all the hype about Star facing off against [[spoiler:Toffee, he dies rather quickly after getting resurrected with Star blasting him while in her SuperMode and Ludo crushing the last remaining bits of him under a tower]]. Many fans were understandably disappointed how such a villain was wasted with some going so far to claim he suffered from VillainDecay. But many other fans found the episode to be one of the best, if not ''the'' best episode of the series because [[spoiler:Ludo's character arc that began in "Ludo in the Wild" came to a satisfying conclusion, Toffee's menacing presence despite the lack of a longer battle, Toffee's liquid form, the return of the Whispering Spell, Star and Marco finally reuniting and hugging, and Star's GoldenSuperMode being achieved, plus Toffee's defeat being considered fitting due to [[HoistByHisOwnPetard it being partially a result of mistakes he himself made]] and a victory for [[TheDogBitesBack his biggest victims, Star and Ludo.]]]]
* The second half of the series, in particular the events of Season 3, have proven divisive amidst the fandom:

** The ShipTease. As detailed in RomanticPlotTumor, Season 3 teased numerous ships while also attempting to sink others: Star tries to get over Marco and gets back with Tom. Jackie breaks up with Marco and he develops an unrequited crush on Star. Marco then receives ShipTease with Kelly... in the exact same episode he finally acknowledges his feelings for Star.

This group also notes that while previous seasons might've had a ton of ship tease, they rarely had whole episodes devoted ''solely'' to it.

This group also notes that while previous seasons might've had a ton of ship tease, they rarely had whole episodes devoted ''solely'' to it.
** The overall tonal shift. While the final two seasons still have its more goofy, lighthearted episodes, the series moved away from more comedic, episodic fare that dominated the first two seasons to more dramatic, serialized stories for its final two. Some fans feel that the show handled its CerebusSyndrome pretty well and managed to successfully transition into something more serious while still juggling its usual comedy. Others think that the crew completely fumbled all the ideas and concepts they had in their attempt to tackle the themes of family and racism, wishing it was never tried at all and that they just stuck to the format of the previous seasons.

* There's a rift between those who [[FanPreferredCouple ship Star and Marco]] and those who prefer them as PlatonicLifePartners, with the latter feeling tired and bored about the typical cliché of "the two main characters of the opposite sex who eventually fall in love and become the OfficialCouple" while the former either disagree with that reasoning or agree in principle but think that the show itself [[TropesAreTools has been executing the friends-to-lovers trope extremely well]], and that Star and Marco's chemistry more than compensates for that cliché.

* The CerebusSyndrome that the show began undergoing in Season 2. Some fans accepted it with open arms and saw the show's greater emphasis on plot and character development as a welcome addition. Others felt the show fumbled in trying to deliver a more intense, continuity heavy story, seeing it as something completely unnecessary, or even damaging, for what was initially just a fun comedy.

* The events of Season 3 as a whole have proven divisive amidst the fandom:
** The decision to leave Earth as a setting in favor of Mewni. Some were fine with it, feeling Earth had plenty of time in the spotlight for the first two seasons and that Mewni had a large amount of untapped potential, ranging from the Butterfly family history to the ongoing racial tensions between Mewmans and Monsters. Others, however, felt it shafted the Earth cast outside Marco and [[AscendedExtra Janna]], and left potential plot threads [[LeftHanging hanging open]]. The latter group also had members who noted that the separation between Earth and Mewni was completely arbitrary anyway, given that dimensional scissors (which both Star and Marco had easy access to) make travel between different worlds literally easier than walking across the street, meaning that an increased focus on Mewni never required abandoning Earth at all.
** Marco's characterization was divisive. Some believe Marco had TookALevelInJerkass or was constantly grabbing the JerkassBall,[[note]]His frustration at not really being a knight, his feud with the other squires, and him not telling Hekapoo about Star causing the portals just so he can keep working with her.[[/note]] and that his boredom with Earth came out of left field. Others believe Marco's characterization was a natural progression of the insecurities he's always displayed, and his need to prove himself was blinding him to the consequences. Many in the latter group felt that it wasn't Marco who grabbed the JerkassBall at all, but that the Mewni characters had a firm hold on it.[[note]]Marco had every reason to expect to be made a knight seeing as King River specifically promised to do so, and the fact that he gave Marco his meat blanket and pretended it was a cape and somehow expected that Marco would never come back is inexplicably stupid even for [[TheDitz River]]. The other squires acting as if Marco didn't earn his position was pretty dubious seeing as, unlike Marco, they were all missing in action during the fight against Ludo and Toffee.[[/note]]
** The ShipTease. As detailed in RomanticPlotTumor, Season 3 teased numerous ships while also attempting to sink other ships. Star tries to get over Marco and gets back with Tom. Jackie breaks up with Marco and he develops an unrequited crush on Star. Marco then receives ShipTease with Kelly... in the exact same episode he finally acknowledges his feelings for Star. Finally, he ends up angering Hekapoo into stopping their adventures together.[[note]]If you're keeping track, that's Starco half teased/half sunk, Tomstar at sail, Kellco teased, Markapoo sunk, and Jarco sunk.[[/note]] Some, such as those that favor the ships teased, were perfectly okay with it and note that teasing ships wasn't something new to the show. Others however, even among those who favored the winning pairings, felt it was pointless and distracted from other aspects such as the lore and comedy, and note that while previous seasons might've had a ton of ship tease, they rarely had whole episodes devoted ''solely'' to it.

* Tom. While a lot of fans agree that he is a good character, the divide lies in whether or not one should judge him for manipulating Star. Half the fanbase points out that Tom was a terrible boyfriend to Star, with DomesticAbuse implied, and keeps trying to manipulate her. The other half points out that he's actively trying to change himself and manage his temper; in "Mr. Candle Cares", he finally got the message that [[spoiler:forcing Star to be with him wouldn't work and that for better or for worse Marco's looking out for Star as a friend and thus will protect her.]] However, he became even more of a base-breaker when [[spoiler: he and Star got back together again]] in Season 3. Added to that, a number of fans feel he's become a wasted presence as a result, considering a lot of episodes in that season have him do nothing but passively react to most situations.

* Queen Moon became one as Season 3 progressed. Due in part to how controlling she was of Star, with complaints that she was a terrible queen.[[note]]Being too blinded by prejudice against monsters, too stubborn to see how misguided it is, neglecting their problems, denying there being a problem like it's below her pay grade when Star calls her out on it, etc.[[/note]] On the other hand, some fans found her behavior was understandable. Her DarkAndTroubledPast gives her a legitimate FreudianExcuse to distrust monsters[[note]]Her mother, Queen Comet, was assassinated by the Monster Leader's treacherous General, Toffee, in the midst of signing a Peace Treaty.[[/note]], and Moon was implied to not be the first royal family member to hate monsters[[note]]If the Mewman's depiction of Eclipsa running off with a monster, brainwashing of [[spoiler:Meteora]], children's book for Mewnipendence Day, and implication that a former Mewman Royal Family Member ordered Mina Loveberry to make sure [[spoiler:Meteora]] does not come back to her nursery, are any indication.[[/note]], nor is the prejudice solely from her, but from the Magic High Commission as well.

* Glossaryck ''in spades''. He's either a funny character who has a strangely compelling way of giving wisdom and helping others, or he's an annoying troll who's too unlikable due to how he almost ''never'' does anything directly, and just expects others to follow what he says without being clear, all intentionally. His entries under UnintentionallyUnsympathetic don't help out.

* The GrandFinale "Cleaved" had basically [[Pun cleaved]] the fan base in more ways than one, especially with [[spoiler:Star destroying all magic in the Multiverse, meaning that all the magical beings like her spells are dead.]] While some viewed it as a bold form of closure for the series, others just found it very anticlimactic, unresolved, and very unfulfilling for a finale.

* Ludo [[spoiler:[[HijackedByGanon being ousted from the spot of main villain by Toffee]] yet again]] in Season 2. Obviously, [[spoiler:fans of Toffee were pleased he's back and affirming himself as the overall BigBad]], but others felt that [[spoiler:it rendered Ludo's [[TookALevelInBadass slow climb to an actual threat]] null and void, and painted him as existing solely to be [[HarmlessVillain a villain that does nothing]] and get hijacked by bigger threats]]. [[spoiler:This was somewhat mitigated by Ludo being placed back in control of himself in order to pull off his actual slow-building invasion plan in ''The Battle for Mewni'', and mitigated even further at the end of said movie when Ludo took revenge for the hijacking by being the one to actually ''kill'' Toffee.]]

* The breakup between Jackie and Marco. Some were happy with the break up due to disliking the pairing. Others were disappointed/angered because it could've had more focus before it ended, as only three episodes (including ''Bon Bon the Birthday Clown'') prior to the break-up showcased their relationship. The previously-mentioned objection towards the separation between Earth and Mewni also played a role in this, as many felt the reason the breakup happened so quickly was solely because the Earth setting was being phased out and Jackie was an "Earth" character who was deemed to have no role in the new all-Mewni setting. Jarco shippers, and just Jackie fans in general, found this particularly galling since ''other'' "Earth characters" still get to drop in and visit Mewni just fine. On the other hand, many fans found the actual breakup scene itself to be well-written and emotionally satisfying, even ones who wished it hadn't happened so quickly.
* Star and Tom getting back together has proven heavily divisive. Due to the implication that their relationship was formerly toxic and abusive and the fact that Tom himself was always a very divisive character, this was inevitable. One party was perfectly okay with Tom getting back with Star, citing Tom's CharacterDevelopment as evidence against the relationship becoming abusive again. Another party saw it as the show advocating getting back together with an abusive ex, and think no matter how much Tom attempts to change, he will revert to being an abuser (or just unwilling to forgive Tom even if he ''has'' changed for the rape-like implication of his previous attempt to bind Star's soul to his own against her will). A third party was willing to wait and see, having hope that Tom's CharacterDevelopment would hold but also being weary in the event something happens. A fourth party just hated the ship altogether due to it interfering with '''other''' ships that they preferred.[[note]]On the Star side, namely Starco, on the Tom side, namely Tomco.[[/note]] Among all the groups opposed to the [=TomStar=], it's widely seen as [[ShockingSwerve coming completely out of left field with zero setup]] (Star goes from hating Tom to wanting him to be just a friend to being willing to go on a date with him in the space of ''literally less than 5 minutes''), in sharp contrast to how Marco's relationship with Jackie and Star's feelings for Marco were both built up gradually over an entire season.

* The GrandFinale "Cleaved" was very controversial, especially with [[spoiler:Star destroying all magic in the Multiverse, meaning that all the magical beings like her spells are dead.]] While some viewed it as a bold form of closure for the series, others just found it needlessly cruel.

* Despite his popularity for [[VileVillainSaccharineShow being a good, competent, serious and effective villain]], there are a handful of people who don't like Toffee. Some believe he's too serious and out of place for a show like ''Star vs.'', and/or consider him boring. Ultimately, [[TheyWastedAPerfectlyGoodCharacter his full potential remains unrealized]]. Despite the fact that he [[spoiler: most likely died in the otherwise superb ''The Battle for Mewni'' and is unlikely to return this time, most of his motivations for what he did still remain unclear beyond the most basic level of {{Revenge}}.]] Not helping matters was WordOfGod claiming he was [[WellIntentionedExtremist a morally complex character]] with VillainHasAPoint, something ''[[InformedAttribute not clearly expressed any time he was on-screen]]'', only vaguely implied with a situation he was in during a ''flashback''. At the same time, some fans were attracted to Toffee ''because'' of how mysterious he was and feel like answering everything would lessen him. The fact that Toffee did come to have his backstory explained in ''The Book of Spells'' didn't help matters, with debates refueling again over why such information never made it into the show proper.
* Jackie-Lynn Thomas became one big time after she and Marco finally [[RelationshipUpgrade became]] an OfficialCouple, which earned her [[DieForOurShip quite a lot of backlash from]] [[FanPreferredCouple Starco shippers]]; but really, it mostly boils down to whether you're either a Starco or a Jarco shipper, with her actual personality being seen as either compelling or boring. Season three made this worse, as she made no appearence in ''Battle of Mewni'', and when she does show up again in "Sophomore Slump", it's to [[spoiler: break up with Marco]]. Fans who like her hate that she was written out before her character could be properly fleshed out, all so Starco can happen guilt free. Meanwhile her haters like it for basically the same reason. [[spoiler: And Starco ''still'' doesn't happen, as Star rekindled her relationship with Tom by that point]].

** Interestingly enough, this went in the opposite direction in season 3, where she's less impulsive, more reasonable, and more willing to be there for others. The base is split in three camps: those who thought she's annoying and not that interesting anymore, those who were open to the change but thought it wasn't handled well, and those who think this is a natural progression of her character.
** Her behavior towards Marco in Season 3 has become another source of controversy. Some think that she is acting needlessly nasty and even cruel toward him; others, on the other hand, think that she is acting reasonable, because she has been attempting to move past her crush of him and Marco burst into her life without warning, when she had reordered her priorities now that she returned to Mewni and faced Toffee.
* On that note, Marco in Season 3 has also gained many detractors due to how badly he handled everything following ''The Battle for Mewni'' by [[spoiler: not admitting to Star that he had feelings for her too when he had the chance, obsessing over Star and Mewni while ignoring everyone and everything on Earth, leading to Jackie breaking up with him, then being generally useless as Star's squire when he returned to Mewni.]]
* Queen Moon became one as Season 3 progressed. Due in part to how controlling she is of Star, and now there are complaints that she is a terrible queen.[[note]]Being too blinded by prejudice against monsters, too stubborn to see how misguided it is, neglecting their problems, denying there being a problem like it's below her pay grade when Star calls her out on it, etc.[[/note]] On the other hand, some fans find that her behavior is understandable. Her DarkAndTroubledPast gives her a legitimate FreudianExcuse to distrust monsters [[note]]Her mother, Queen Comet, was assassinated by the Monster Leader's treacherous General, Toffee, in the midst of signing a Peace Treaty.[[/note]], and Moon is implied to not be the first royal family member to hate monsters[[note]]If the Mewman's depiction of Eclipsa running off with a monster, brainwashing of [[spoiler:Meteora]], children's book for Mewnipendence Day, and implication that a former Mewman Royal Family Member ordered Mina Loveberry to make sure [[spoiler:Meteora]] does not come back to her nursery, are any indication.[[/note]], nor is the prejudice solely from her, but from the Magic Commission as well.

* Glossaryck has this trope ''in spades''. He's either a funny character who has a strangely compelling way to give wisdom and help others, or he's an annoying troll who's too unlikable due to how he almost ''never'' does anything directly, and just expects others to follow what he says without being clear, all intentionally. His entries under unintentionally unsympathetic don't help out.
* [[spoiler: Miss Heinous, aka Meteora, is in a ''really'' weird position. During her times as Miss Heinous, she was either a compelling villain who brought up interesting points on individuality, or an annoying strawman who tries and fails to be serious. After "Monster Bash", where she finds out that she's Eclipsa's daughter Meteora, things went in a different direction. Her much more monstrous personality, both figuratively and later on literally, is either understandable given that she is the rightful heir to the throne, or she's essentially just an overgrown child throwing a temper tantrum, and is little more than a one note bad guy.]] It's safe to say that there's no middle ground for her character.

* "Toffee", the final episode of ''The Battle for Mewni'', was considered a letdown for some though it lived up to the hype for a lot of other fans. For all the hype about Star facing off against [[spoiler:Toffee, he dies rather quickly after getting resurrected with Star blasting him while in her SuperMode and Ludo crushing the last remaining bits of him under a tower]]. Many fans were understandably disappointed how such a villain was wasted with some going so far to claim he suffered from VillainDecay. But many other fans found the episode to be one of the best, if not ''the'' best episode of the series so far because [[spoiler: Ludo's character arc that began in the season 2 premiere came to a satisfying conclusion, Toffee's menacing presence despite the lack of a longer battle, Toffee's liquid form, the return of the Whispering Spell, Star and Marco finally reuniting and hugging, and Star's GoldenSuperMode being achieved, plus Toffee's defeat being considered fitting due to [[HoistByHisOwnPetard it being partially a result of mistakes he himself made]] and a victory for [[TheDogBitesBack his biggest victims, Star and Ludo.]]]]

** The decision to leave Earth as a setting and focus more on Mewni. Some are fine with it, feeling Earth had plenty of time in the spotlight for the first two seasons and that Mewni has large amounts of untapped potential, ranging from the Butterfly family history to the ongoing racial tensions between Mewmans and Monsters. Others, however, feel it shafts the Earth cast outside Marco and [[AscendedExtra Janna]], and leaves potential plot threads [[LeftHanging hanging open]].

And the other squires acting as if Marco didn't earn his position is pretty dubious seeing as, unlike Marco, they were all missing in action during the fight against Ludo and Toffee.[[/note]]
** The ShipTease. As detailed in RomanticPlotTumor, Season 3 so far has teased numerous ships while also attempting to sink other ships. Star tries to get over Marco and gets back with Tom. Jackie breaks up with Marco and he develops an unrequited crush on Star. Marco then receives ShipTease with Kelly...in the exact same episode he finally acknowledges his feelings for Star. Finally, he ends up angering Hekapoo into stopping their adventures together.[[note]]If you're keeping track, that's Starco half teased/half sunk, Tomstar at sail, Kellco teased, Markapoo sunk, and Jarco sunk.[[/note]] Some, such as those that favor the ships teased, are perfectly okay with it and note that teasing ships isn't something new to the show. Others however, even among those who favor the winning pairings, feel it is pointless and distracts from other aspects such as the lore and comedy, and note that while previous seasons might've had a ton of ship tease they rarely had whole episodes devoted ''solely'' to the teasing.
* The GrandFinale "Cleaved" is very controversial, especially with how [[spoiler: Star destroys all magic in the Multiverse meaning that all the magical beings like her spells are dead.]] While some viewed it as a bold form of closure for the series, others just found it needlessly cruel.

* Ludo [[spoiler:[[HijackedByGanon being ousted from the spot of main villain by Toffee]] yet again]] in Season 2. Obviously, [[spoiler:fans of Toffee were pleased he's back and affirming himself as the overall BigBad]], but others felt that [[spoiler:it rendered Ludo's [[TookALevelInBadass slow climb to an actual threat]] null and void, and painted him as existing solely to be [[HarmlessVillain a villain that does nothing]] and get hijacked by bigger threats]]. [[spoiler: This was somewhat mitigated by Ludo being placed back in control of himself in order to pull off his actual slow-building invasion plan in ''The Battle for Mewni'', and mitigated even further at the end of said movie when Ludo takes his revenge for the hijacking by being the one to actually ''kill'' Toffee.]]
* The CerebusSyndrome that the show began undergoing in the second season. Some fans accepted it with open arms and saw the show's greater emphasis on plot and character development as a welcome addition. Others feel the show fumbles in trying to deliver a more intense, continuity heavy story, with those who see even the attempt as something which was completely unnecessary, or even damaging, for what was initially just a fun comedy.
* The LGBT crowd was ''not happy'' with the scene of Heinous showing Marco's chest hair in "Princess Turdina" to oust him in front of the crowd, as it made them incredibly uncomfortable by the message it was trying to do, while some didn't think it too bad.
* The breakup between Jackie and Marco has a mixed reception with the fanbase. Some are happy with the break up due to disliking the pairing. Others were disappointed/angered because it could've gotten more screen time and focus before it ended, as only three episodes (including ''Bon Bon the Birthday Clown'') prior to the break-up showcased their relationship. The previously-mentioned objection towards the separation between Earth and Mewni also plays a role in this, as many feel the reason the breakup happened so quickly was solely because the Earth setting was being phased out and Jackie was an "Earth" character who was deemed to have no role in the new all-Mewni setting. Jarco shippers, and just Jackie fans in general, found this particularly galling since ''other'' "Earth characters" still get to drop in and visit Mewni just fine. On the other hand, many fans found the actual breakup scene itself to be well-written and emotionally satisfying, even ones who wished it hadn't happened so quickly.
* Star and Tom getting back together has proven heavily divisive. Due to the implication that their relationship is formerly toxic and abusive and the fact that Tom himself was always a very divisive character, this was inevitable. One party is perfectly okay with Tom getting back with Star, citing Tom's CharacterDevelopment as evidence against the relationship becoming abusive again. Another party sees it as the show advocating getting back together with an abusive ex, and think no matter how much Tom attempts to change, he will revert to being an abuser (or just unwilling to forgive Tom even if he ''has'' changed for the rape-like implication of his previous attempt to bind Star's soul to his own against her will). A third party is willing to wait and see, having hope that Tom's CharacterDevelopment will hold but also being weary in the event something happens. A fourth party just hates the ship altogether due to it interfering with '''other''' ships that they prefer.[[note]]On the Star side, namely Starco, on the Tom side, namely Tomco.[[/note]] And among all the groups opposed to the [=TomStar=], it's widely seen as [[ShockingSwerve coming completely out of left field with zero setup]] (Star goes from hating Tom to wanting him to be just a friend to being willing to go on a date with him in the space of ''literally less than 5 minutes''), in sharp contrast to how Marco's relationship with Jackie and Star's feelings for Marco both got built up gradually over an entire season.
** The fact that [[spoiler:Star and Marco's first kiss happened while she was still dating Tom]] was immediately controversial, even if it did happen under duress. On one hand, there are a number of fans who felt that [[spoiler:the kiss was forced and that Marco looked like a jerk for making Star "cheat" on Tom. However, others point out that he had good intentions since the two of them wouldn't have been able to leave the photo booth (or at least, genuinely thought they couldn't) unless such action was taken. It's also been pointed out that Tom has done worse things to Star and probably [[NotSoDifferent wouldn't have been much different]], along with Star seeming to be aware that she was still with Tom during her moment of shock afterwards. [[TakeAThirdOption There's also a third group of people -specifically the more diehard Starco shippers-]] that don't care about any of the above as long as the two finally got to kiss]].
* While a lot of fans liked the early reveal that the Mewmans were the invaders, and the monsters were the victims of colonialism, some are divided on the lengths the show had gone with it since, feeling it's become {{Anvilicious}} in its messaging.

* Glossaryck has this trope ''in spades'' . He's either a funny character who has a strangely compelling way to give wisdom and help others, or he's an annoying troll who's too unlikable due to how he almost ''never'' does anything directly, and just expects others to follow what he says without being clear, all intentionally. His entries under unintentionally unsympathetic don't help out.
