History YMMV / MobileSuitGundamTheWitchFromMercury

* TheyChangedItNowItSucks: The majority of the fandom rejoiced at the final episode containing a scene of Suletta and Miorine wearing matching rings, with many people -- including those who worked on the show -- taking it as confirmation they got married. However, in late July 2023 Bandai Namco Entertainment redacted an unscripted statement in an interview with one of the voice actors that Suletta and Miorine were married, and in response to confusion stated that they were not officially married and their relationship was up to viewer interpretation. This was met with immediate outrage by the fandom, especially LGBTQ+ members, with the series' ratings tanking overnight in the wake of the announcement.

* SweetnessAversion: Many viewers, especially those who were fans of older ''Gundam'' entries that had [[BittersweetEnding bittersweet]] or outright [[DownerEnding downer]] endings, criticized the show's finale as wrapping up a little ''too'' perfectly. [[spoiler:Outside a few skirmishes, there was no climactic battle between the opposing parties involved, [[EverybodyLives no named characters die]], Prospera is convinced to give up her revenge plot with seemingly little effort, and all of the major conflicts of the show are either [[AssPull handwaved away]] or [[AbortedArc completely forgotten about]]]].

* TheyChangedItNowItSucks:
** Some old-school Gundam fans have declared the series "not proper Gundam" due to the school setting and there not being a war going on, and said to be lighter and softer than previous series, though this opinion has largely been quashed with the release of Episodes 5 and 6, and then later utterly demolished with the release of [[WhamEpisode Episode 12]]. Completely demolished with [[AnyoneCanDie Episode 20]], when the school is subject to horrific death and destruction.

Completely demolished with [[AnyoneCanDie Episode 20]], when the school is subject to horrific death and destruction.

* ItsShortSoItSucks: For the majority of the fans, the most common issue with the show is that the story crams itself to fit into 24 episodes which many felt about the ending being inadequate and rushed. While most are okay with Suletta and Miorine's ending, many are unsatisfied with the way how the story wraps itself as there are still some storylines left unresolved (e.g. the ongoing conflict between the Earthians and Spacians and the mystery behind Nortrette Rembran's death). This is also why fans want to explore the Ad Stella universe more and hope for possible side stories and sequels.

** The final confrontation of the series, which involves several characters [[spoiler: who are beyond the shadow of a doubt dead]] coming in to [[BigDamnHeroes help Suletta and friends]] at an important time of need and convince [[spoiler: Prospera that everyone she is attempting to enact revenge for is proud of her]]. Also [[spoiler: Eri survived by going into a keychain]] which not even the in universe characters seem able to explain.

* SugarWiki/SuperlativeDubbing: The show’s English dub has earned a lot of praise, particularly for the casting of Creator/JillHarris and Creator/NatalieVanSistine as Suletta and Miorine respectively, with the former perfectly portraying Suletta’s kind and earnest nature and the latter capturing both the abrasive and gentler sides of Miorine’s personality.

** Thanks to Miorine calling her sex-crazed, many took Suletta as some kind of sex obsessed partner who is constantly out to bed her, [[spoiler:with some pulling a {{Yandere}} spin on her thanks to episode 12]]. Of course, just as many portrays it as Miorine simply projecting and that ''she'' is the one who is sex-crazed, [[spoiler:even going so far as to try and take advantage of Suletta's BlindObedience for some easy sex]].

* AssPull: While the existence of [[spoiler:a Gundam named after the character Caliban was popular speculation since the beginning for those familiar with ''Theatre/TheTempest'']], the casual [[ThereIsAnother mention]] of [[spoiler:Gundam Calibarn]] came out of nowhere and has no foreshadowing. The only things that Guston mentioned about its origins is that [[spoiler:the Calibarn is a Gundam confiscated by the Space Assembly League during the Vanadis Incident]] and that's it.

** Likewise, the reveal that [[spoiler:the Space Assembly League has their own version of a Colony Laser disguised as a laser communications facility, which they use to fire at the Benerit Group headquarters in an attempt to destroy it, is never brought up again]].

** The Dawn of Fold, particularly its leaders Naji and Olcott, who are played off as {{Well Intentioned Extremist}}s who are fighting for Earthian rights, [[spoiler:basically disappear from the plot after their DayInTheLimelight in episode 15. They never again come into direct conflict with the protagonists, and we never get to find out their greater motivations for leading Dawn of Fold, their exact relationships with Sophie and Norea, or what exactly caused Olcott to defect from Cathedra]].

** The series would also clash with ''Anime/MobileSuitGundamIronBloodedOrphans'', particularly those who are introduced to the franchise through the latter. The conflict usually stems from the LighterAndSofter tone of ''The Witch from Mercury'', with ''Iron-Blooded Orphans'' fans claiming that it should be DarkerAndEdgier because they believe TrueArtIsAngsty and that there should be many deaths. They even disparaged the ending for being too happy and that it should have a BittersweetEnding with some of the main characters dying. ''The Witch from Mercury'' fans retorted this saying that the show doesn't need to be very dark like some of the previous entries because it's in a different setting and pointed out that the previous shows before ''Iron-Blooded Orphans'' had the main cast surviving in the past and earning their happy endings. Likewise, they find that needlessly killing off characters just for the sake of shock value to be detrimental. Ironically, most fanart enjoys depicting Mikazuki and Suletta as friends, and the general mecha fandom would love to see how both series interact in ''VideoGame/SuperRobotWars''.

** Shaddiq has picked up a bit of this reputation as the show's gone on. In addition to suffering an embarrassing defeat in the dueling ring (his tunnel vision leads to him getting sniped by a heavily damaged obsolete mobile suit that his shiny AceCustom should've been able to eat for breakfast) his [[CondescendingCompassion motivations]] for interfering with Miorine's company and [[CockFight enmity with Suletta]] have led to him being mocked for being an EntitledToHaveYou "nice guy", especially with Suletta's dancing and reciting the GUND-ARM Inc. jingle at the end of the duel being interpreted as unintentional teabagging at his expense to rub salt to his wound. More than a few fan works portray Miorine going out of her way to [[JealousRomanticWitness rub her engagement with Suletta in his face]] and him subsequently [[spoiler:calling a hit on her father and shrugging her off as potential collateral damage]] [[AlternateCharacterInterpretation is sometimes viewed as him lashing out]]. To add insult to injury, said AceCustom, as well as Shaddiq-related merchandise has had ''terrible'' sales in real life. And this is taking into account that ''G-Witch'' has had absolutely ''absurd'' overall sales, the most for ''Gundam'' ever.

* EvilIsSexy:
** Prospera Mercury again, for the same reasons as EvilIsCool above.
** Renee Costa is Felsi Rollo's EvilCounterpart in the sense that they look nearly identical, but Renee [[spoiler:is in on Shaddiq's destructive plans]], while Felsi is a JerkWithAHeartOfGold. Notably, Renee wears a CustomUniform that shows a lot of skin, while Felsi wears her uniform to conservative regulations.

** Prospera Mercury is seen by many fans as one of the most chilling CharClone in the franchise, being calculating, emotionally manipulative, and a long-term planner who rarely gets a scene where she doesn't look like she is in control of everything and everyone around her. For many, she is both a hateable villain and one of the best things in the show.

** There are naturally a lot of ''Anime/CodeGeass'' fans as Ichirō Ōkouchi wrote both series. This has led to a lot of parallels of the ''G-Witch'' cast to the ''Code Geass'' cast, and people that are terrified of ''G-Witch'' having similar tragedies in the future.

** The Gundam Schwarzette. [[spoiler:After several episodes worth of buildup, it only got some incredibly limited screen time. While it got to show off quite a bit in that limited space, many were left disappointed that for all the buildup, it was such a quickly done and over with affair. This was made worse with the release of the Gunpla that reveals that it had even more features it never got to show off. The fact that it also ended up being piloted by a very divisive character rather than a more popular one didn't help people's perception of it either]].

** The completed Demi Barding. [[spoiler:While the unfinished version got to see some action in the hands of Chu-chu during the Asticassia attack, the finalized version launched during the final battle got to see no combat whatsoever, only ever serving as a glorified transport truck with its new equipment serving as little more than window dressing]].

** The NewbieBoom ''G-Witch'' brought about includes a lot of ''Franchise/KamenRider'' fans, resulting in a fandom overlap intertwining both franchises and leading to various comparisons and jokes for multiple installments, due to a lot of surprisingly plot-specific similarities as well as the general theme of cybernetic augmentations seen in most Showa-era entries.

* TheyWastedAPerfectlyGoodCharacter: The original Elan. [[spoiler:You'd think that with the way he remained as a background character all throughout the whole show, he was being built up to be a major villain down the line that Suletta and company would have to fight against. However, it ended up never reaching a point for him to step into the limelight and takeover. Only in the last minute does the original Elan actually end up doing anything, and it's just to team up with Guel from a business standpoint]].
