History BrokenBase / Toonami

* ''WesternAnimation/KingStarKing'' suffered a brutal backlash when it was played during the 2013 DST Hour alongside ''WesternAnimation/KorgothOfBarbaria'' and ''Kick-Heart'', to the point where Toonami's showrunner ran a Website/{{Twitter}} poll asking whether they should replay the DST Hour again the next year or do something experimental. The verdict? [[https://twitter.com/Clarknova1/status/397164256984330241 "Experimental by a huge margin. As long as it's NOT King Star King!"]] There were a few people here and there who did like ''King Star King'', but they were greatly outnumbered by those who didn't.

* The business partnership between Creator/{{Funimation}} and Website/{{Crunchyroll}} and its impact on Toonami. While generally agreed to be amazing for the anime industry overall, Toonami fans are more divided. Some see the partnership as something that could hurt the block, as Funimation could end up prioritizing streaming over television, resulting in less shows for the block. Others argue that the partnership won't actually hurt Toonami, and in fact could be beneficial since they could have access to shows from Crunchyroll's catalogue (with requested favorites including ''Webcomic/MobPsycho100'' and ''Anime/NinetyOneDays'', the former of which was picked up by Toonami in October 2018).

* ''WesternAnimation/ThunderCats2011'' and ''WesternAnimation/SymBionicTitan''... or rather, the fact that they were added to the lineup in the first place. Anime fans insisted that Toonami should stick exclusively to anime and that their acquisition of western shows was a form of NetworkDecay (these same fans forget that Toonami was never meant to be an anime-only block in the first place; the original 1997 lineup was almost entirely Western toons, and even the anime-dominated "classic" Toonami of the early 2000s included the likes of ''WesternAnimation/ThunderCats1985'', ''WesternAnimation/ReBoot'', almost all of the Franchise/DCAnimatedUniverse shows, ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'', and even ''WesternAnimation/ThePowerpuffGirls'' in its mix). Others were either happy about or didn't really mind the addition of western animation. We can also add ''WesternAnimation/StarWarsTheCloneWars'', ''WesternAnimation/BewareTheBatman'', and ''WesternAnimation/SamuraiJack'' to the list. Interestingly, the more adult-oriented final season of ''Samurai Jack'' mostly averted this, with audience reaction and ratings being rather positive.

* Debates on whether ''LightNovel/SwordArtOnline'' would make it to Toonami were full with this. When the sub aired, there was considerable demand at first and fans regarded it as a good GatewaySeries, but the detractors became more vocal as the series went on (especially in regards to the Fairy Dance arc), and accused it of being heavy on "[[PanderingToTheBase otaku pandering]]" and WishFulfillment, elements perceived to not fit well with Toonami's emphasis on being a gateway drug to the anime medium. Ultimately, when it was time for the decision, [[CriticalBacklash the block's creators thought that]] [[http://toonami.tumblr.com/post/54263109126/do-you-have-any-concerns-about-the-incest-subplot-in the negative aspects]] [[http://toonami.tumblr.com/post/54258600250/someone-is-gonna-ask-this-anyway-so-i-figured-i-get-it weren't a big deal.]] The show would be a ratings success regardless, and would lead to the advent of more Creator/{{Aniplex}} shows airing on the block, including ''SAO''[='s=] second season two years later. They did mention, however, that ''SAO''[='s=] SeasonalRot [[http://toonami.tumblr.com/post/54261782321/is-the-reason-youre-telling-people-to-wait-until-titan is one of the reasons why]] [[http://toonami.tumblr.com/post/54259682512/have-you-all-had-a-chance-to-watch-any-of-attack-on fans shouldn't rush to request a show]] [[http://toonami.tumblr.com/post/54259923178/what-are-the-chances-of-getting-attack-on-titan-when until they see how a show "turns out",]] as mentioned when asked if ''Manga/AttackOnTitan'', which at the time was another largely requested show, would eventually air on Toonami. [[note]]''Attack on Titan'' would eventually be added to the Toonami lineup a year later.[[/note]] With the ''SAO'' anime (and the franchise as a whole) becoming even more divisive as it went on, it should surprise no one that it remained a Broken Base all the way through all three parts of Season 3, especially since it usually had one of the prime timeslots on the block.

* ''WesternAnimation/ThunderCats2011'' and ''WesternAnimation/SymBionicTitan''... or rather, the fact that they were added to the lineup in the first place. Anime fans insisted that Toonami should stick exclusively to anime and that their acquisition of western shows was a form of NetworkDecay (these same fans forget that Toonami was never meant to be an anime-only block in the first place; the original 1997 lineup was almost entirely Western toons, and even the anime-dominated "classic" Toonami of the early 2000s included the likes of ''WesternAnimation/ThunderCats1985'', ''WesternAnimation/ReBoot'', almost all of the Franchise/{{DCAU}} shows, ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'', and even ''WesternAnimation/ThePowerpuffGirls'' in its mix). Others were either happy about or didn't really mind the addition of western animation. We can also add ''WesternAnimation/StarWarsTheCloneWars'', ''WesternAnimation/BewareTheBatman'', and ''WesternAnimation/SamuraiJack'' to the list. Interestingly, the more adult-oriented final season of ''Samurai Jack'' mostly averted this, with audience reaction and ratings being rather positive.

* Whether Toonami should focus exclusively on newer shows from the 2010s, or should also dedicate space to older shows from the 2000s and 1990s. Many would argue that shows from the latter years would still fit Toonami (it helps that Toonami ''has'' aired older shows like ''Anime/SamuraiSeven'', ''Manga/BlackLagoon'', ''Anime/TengenToppaGurrenLagann'', and ''Anime/MichikoAndHatchin''), while others argue that Toonami should stay focused on newer shows since they generally do better in the ratings. This argument also extends to whether or not Toonami should bring back shows from the [adult swim] Action era like they did with ''Anime/EurekaSeven'' and ''Anime/SamuraiChamploo'', with some fan favorites from that era being ''Anime/CodeGeass'', ''Manga/DeathNote'', and the [[Anime/FullmetalAlchemist 2003]] ''Anime/FullmetalAlchemist'' [[Anime/FullmetalAlchemist anime]].

* The business partnership between Creator/{{Funimation}} and Website/{{Crunchyroll}} and its impact on Toonami. While generally agreed to be amazing for the anime industry overall, Toonami fans are more divided. Some see the partnership as something that could hurt the block, as Funimation could end up prioritizing streaming over television, resulting in less shows for the block. Others argue that the partnership won't actually hurt Toonami, and in fact could be beneficial since they could have access to shows from Crunchyroll's catalogue (with requested favorites including ''Manga/MobPsycho100'' and ''Anime/NinetyOneDays'', the former of which was picked up by Toonami in October 2018).

* Toonami's length being cut down from 6-and-a-half hours to 3-and-a-half in February 2020 due to low ratings, essentially scaling the block back down to the same length it was when it was revived in 2012. Some were upset that Toonami was being cut in half in favor of more [adult swim] reruns, citing that the 2014 Month of Movies wasn't doing well due to low ratings and the lack of budget (notably, [[http://toonamifaithful.com/toonami-ratings-for-january-24th-2015/ on January 25th, 2015]], the lone episode of ''WesternAnimation/KingOfTheHill'' that aired after Toonami ended at 5:30 AM resulted in a ratings drop). Others thought that a smaller block with more premieres and less reruns would hold better ratings, noting that the Toonami crew has less space to worry about and wouldn't have to pad out the block with as many reruns. The only real agreement is that ''Anime/KillLaKill'' had essentially been screwed over due to no longer airing at 11:30 PM as planned, which was later proven wrong with ''KLK'' holding its own airing after ''DBZ Kai'' in the first half of the block.

* An example going back to Toonami's days on Creator/CartoonNetwork is ''Manga/BoboboboBobobo'', a show that, while technically falling under the action genre, was completely balls-to-the-wall insane and thus deemed by some as a questionable choice for the block. The show was even brought up in an early episode of Toonami Pre-Flight discussing Toonami's great failures. It was high up on the official Facebook page's considerations for Toonami's failures, yet Jason [=DeMarco=] said that there were just as many people who wanted to see the show aired again.
* ''Anime/{{Hamtaro}}'' is an adorable anime about cute talking hamsters. That is it. No action, no violence, no explosions. This left Toonami fans broken on whether it should have been on the block or not. It also caused a related issue with the [adult swim] revival, as fans of numerous slice of life, romance, or comedic anime want their anime on Toonami because ''Hamtaro'' was allowed.

* The insistence on Toonami being mainly action block. Most viewers got into it for the action shows anyway, but this being the only TV block that shows anime at all, some were upset about anime devoid of action not having a chance at being shown (to the point that ''Manga/DeathNote'', one of the more heavily requested shows for the block, is a non-action show). It doesn't help that the few instances of non-action shows airing on Toonami have been hit-or-miss (''Hamtaro'' and ''Tenchi Muyo GXP'' were universally agreed to not fit the block at all, while ''Bobobo-bo Bo-bobo'' and ''Space Dandy'' were more successful if not without detractors).

* {{Anime}} vs WesternAnimation: An argument over whether Toonami should air exclusively anime or rather slots should also be dedicated to WesternAnimation (whether they're Cartoon Network holdovers like ''WesternAnimation/ThunderCats2011'', ''WesternAnimation/SymBionicTitan'', and ''WesternAnimation/BewareTheBatman'', or are more adult-oriented material like the fifth season of ''WesternAnimation/SamuraiJack''). Some have pointed out that they would be fine with Western animation as long as it was aimed for adults, while others have countered that many of Toonami's anime is for children or teenagers in Japan and view such a restriction as hypocritical.

* [[https://www.youtube.com/watch?v=YHfJiZTtGEA Toonami's speech]] on racism and the UsefulNotes/{{Black Lives Matter movement}} caused a big stir. Aside from [[Administrivia/RuleOfCautiousEditingJudgment the usual discourse on the movement as a whole]], there was debate on whether the block itself is a suitable place for such a political statement. While Toonami has had multiple videos emphasizing equality before, this one ended up going viral on social media, thus getting picked up by mainstream media, amplifying the whole debate.

* Toonami's first announced acquisition from Creator/SentaiFilmworks being ''Manga/AkameGaKill'' Some thought that the show is of poor quality and that Toonami could've made a better choice. Others were simply glad that Toonami ''finally'' picked up a show from Sentai Filmworks, something that many thought would never happen. Somewhat alleviated with the later announcement that ''Manga/{{Parasyte}}'' was also picked up for airing.

* {{Anime}} vs WesternAnimation: An argument over whether Toonami should air exclusively anime or rather slots should also be dedicated to WesternAnimation (whether they're Cartoon Network holdovers like ''WesternAnimation/ThunderCats2011'', ''WesternAnimation/SymBionicTitan'', and ''WesternAnimation/BewareTheBatman'', or are more adult-oriented material like the fifth season of ''WesternAnimation/SamuraiJack'').

* The Shows:
** An example going back to Toonami's days on Creator/CartoonNetwork is ''Manga/BoboboboBobobo'', a show that, while technically falling under the action genre, was completely balls-to-the-wall insane and thus deemed by some as a questionable choice for the block. The show was even brought up in an early episode of Toonami Pre-Flight discussing Toonami's great failures. It was high up on the official Facebook page's considerations for Toonami's failures, yet Jason [=DeMarco=] said that there were just as many people who wanted to see the show aired again.
** ''Anime/{{Hamtaro}}'' is an adorable anime about cute talking hamsters. That is it. No action, no violence, no explosions. This left Toonami fans broken on whether it should have been on the block or not. It also caused a related issue with the [adult swim] revival, as fans of numerous slice of life, romance, or comedic anime want their anime on Toonami because ''Hamtaro'' was allowed.
** ''Anime/TenchiMuyoGXP''. Some enjoyed it for being an overall fun show following in the footsteps [[Anime/TenchiMuyoRyoOhki of]] [[Anime/TenchiUniverse its]] [[Anime/TenchiInTokyo predecessors]], while others hated it for being a non-action show airing on Toonami, an action-oriented block (despite the fact that the ''Anime/TenchiMuyo'' series in general isn't action-oriented). Unfortunately, the latter side seemed to have more prevalence, as the show tanked in ratings to the point of [[ScrewedByTheNetwork being moved down to 3:00 AM]] (though in all fairness, ''GXP'' did manage to finish its run and air all 26 of its episodes without getting taken off the lineup), and at least for a time, fans considered it unlikely that any other shows that put less emphasis on action would air on the block.
** ''WesternAnimation/ThunderCats2011'' and ''WesternAnimation/SymBionicTitan''... or rather, the fact that they were added to the lineup in the first place. Anime fans insisted that Toonami should stick exclusively to anime and that their acquisition of western shows was a form of NetworkDecay (these same fans forget that Toonami was never meant to be an anime-only block in the first place; the original 1997 lineup was almost entirely Western toons, and even the anime-dominated "classic" Toonami of the early 2000s included the likes of ''WesternAnimation/ThunderCats1985'', ''WesternAnimation/ReBoot'', almost all of the Franchise/{{DCAU}} shows, ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'', and even ''WesternAnimation/ThePowerpuffGirls'' in its mix). Others were either happy about or didn't really mind the addition of western animation. We can also add ''WesternAnimation/StarWarsTheCloneWars'', ''WesternAnimation/BewareTheBatman'', and ''WesternAnimation/SamuraiJack'' to the list. Interestingly, the more adult-oriented final season of ''Samurai Jack'' mostly averted this, with audience reaction and ratings being rather positive.
** When Toonami came back in 2012, ''Anime/CowboyBebop'' was one of the shows that was previously airing on Creator/AdultSwim and carried over to Toonami. When its run ended, it was taken off along with ''Manga/DeadmanWonderland'' and replaced by ''Anime/SamuraiSeven'' and ''Anime/EurekaSeven''. However, when the block expanded to 6 hours, it was brought back to the lineup. While some fans didn't really mind, other fans were sick of seeing the show to the point where they actually wanted it to be taken off (it was aired nearly non-stop with few breaks since ''September 2001''); the latter group got their wish late in 2014. Unfortunately, the removal of ''Bebop'' flipped the tables, satisfying the people who wanted the show off, but also pissing off the fans who were perfectly fine with it.
*** After a short, incomplete stint in 2015, it returned two years later, eventually completing the entirety of its HD rerun. But then Toonami made the decision to start it [[HereWeGoAgain right from the beginning, without a break]]. Some thought it should remain off of Toonami so the audience could grow to miss it again, while others didn't really care, probably because a lot of them didn't watch the reruns to begin with.
** Debates on whether ''LightNovel/SwordArtOnline'' would make it to Toonami were full with this. When the sub aired, there was considerable demand at first and fans regarded it as a good GatewaySeries, but the detractors became more vocal as the series went on (especially in regards to the Fairy Dance arc), and accused it of being heavy on "[[PanderingToTheBase otaku pandering]]" and WishFulfillment, elements perceived to not fit well with Toonami's emphasis on being a gateway drug to the anime medium. Ultimately, when it was time for the decision, [[CriticalBacklash the block's creators thought that]] [[http://toonami.tumblr.com/post/54263109126/do-you-have-any-concerns-about-the-incest-subplot-in the negative aspects]] [[http://toonami.tumblr.com/post/54258600250/someone-is-gonna-ask-this-anyway-so-i-figured-i-get-it weren't a big deal.]] The show would be a ratings success regardless, and would lead to the advent of more Creator/{{Aniplex}} shows airing on the block, including ''SAO''[='s=] second season two years later. They did mention, however, that ''SAO''[='s=] SeasonalRot [[http://toonami.tumblr.com/post/54261782321/is-the-reason-youre-telling-people-to-wait-until-titan is one of the reasons why]] [[http://toonami.tumblr.com/post/54259682512/have-you-all-had-a-chance-to-watch-any-of-attack-on fans shouldn't rush to request a show]] [[http://toonami.tumblr.com/post/54259923178/what-are-the-chances-of-getting-attack-on-titan-when until they see how a show "turns out",]] as mentioned when asked if ''Manga/AttackOnTitan'', which at the time was another largely requested show, would eventually air on Toonami. [[note]]''Attack on Titan'' would eventually be added to the Toonami lineup a year later.[[/note]] With the ''SAO'' anime (and the franchise as a whole) becoming even more divisive as it went on, it should surprise no one that it remained a Broken Base all the way through all three parts of Season 3, especially since it usually had one of the prime timeslots on the block.
** ''Kick-Heart'', a Website/{{Kickstarter}}-funded 15-minute short produced by Creator/ProductionIG that was aired during Labor Day weekend in 2014, premiering [[MoodWhiplash right after]] ''[[Anime/RebuildOfEvangelion Evangelion 2.22]]'', and again on November 2nd of that year along with ''WesternAnimation/KingStarKing'' (see directly below) and ''WesternAnimation/KorgothOfBarbaria'' as Daylight Savings Time filler. Reception wasmixed, with some liking the surreal artstyle and quality which greatly contrasted that of the shows in Toonami's lineup and better resembled the type of shows that air on regular Creator/AdultSwim, while others despised it for the very same reasons.
** ''WesternAnimation/KingStarKing'' suffered a brutal backlash when it was played during the 2013 DST Hour alongside ''WesternAnimation/KorgothOfBarbaria'' and ''Kick-Heart'', to the point where Toonami's showrunner ran a Website/{{Twitter}} poll asking whether they should replay the DST Hour again the next year or do something experimental. The verdict? [[https://twitter.com/Clarknova1/status/397164256984330241 "Experimental by a huge margin. As long as it's NOT King Star King!"]] There were a few people here and there who did like ''King Star King'', but they were greatly outnumbered by those who didn't.
** ''Anime/SpaceDandy'' was mostly a welcome addition to the block and was AdoredByTheNetwork to the extent that Cartoon Network made a special deal to air the dub hours before the Japanese saw their version of the episodes, but some fans were still miffed that it was a comedy in the middle of an action block (when in fact the show has lots of action anyway, and it sometimes takes on genres other than comedy), while the lack of continuity was annoying to some viewers who regularly expect that in anime. Not helping matters was how the show was heavily advertised as being from the creators of ''Anime/CowboyBebop'', which, while episodic and having comedy elements, also had serious stories and firm continuity. [[spoiler:Until the last few episodes showed that ''Space Dandy'''s apparent NegativeContinuity actually had an in-universe reason.]]
** ''WesternAnimation/BewareTheBatman'', much like the above-mentioned western shows, was not well-received by anime fans ever since Toonami started airing the show at 3:00 AM, replacing ''Anime/GhostInTheShellStandAloneComplex''. What really struck a match, however, was the decision to have the show switch timeslots with ''Manga/BlackLagoon'', which was still premiering its second season at 2:30, in order to place priorities on the unaired episodes. Some thought Toonami had its priorities set in the right place (they had not actually ''premiered'' a western show before, while ''Black Lagoon'' was pushing 10 years old at that point), while others were upset that an anime show that was still premiering was being pushed down to 3:00, the same timeslot that ''Tenchi Muyo! GXP'' was [[ScrewedByTheNetwork relegated to due to low ratings]].

** Toonami's first announced acquisition from Creator/SentaiFilmworks being ''Manga/AkameGaKill'' Some thought that the show is of poor quality and that Toonami could've made a better choice. Others were simply glad that Toonami ''finally'' picked up a show from Sentai Filmworks, something that many thought would never happen. Somewhat alleviated with the later announcement that ''Manga/{{Parasyte}}'' was also picked up for airing.
** Unexpectedly for something considered the long-anticipated return of [[Franchise/{{Gundam}} a Toonami staple]], ''Anime/MobileSuitGundamIronBloodedOrphans'' received a somewhat mixed reception from viewers. One party liked the show and were glad that ''Gundam'' is finally back on Toonami, while the other disliked it for being "too slow" and not having enough action sequences compared to the other shows on the block. This became even more intense with ''IBO''[='s=] second season, which was extremely divisive even among fans of the show.
*** ''Iron-Blooded Orphans'' being picked for a marathon in late October 2016. [[note]]Marathons themselves are already quite divisive, as described down below.[[/note]] While many fans liked that the anime was getting more exposure on behalf of Toonami, choosing the Dort Colonies arc had a polarizing reaction. Fans were glad it wasn't yet ''another'' start-in-the-beginning marathon that Toonami is known for, thus allowing people to rewatch character development, but said arc is also controversial due to a noticeable lack of Gundam fights in much of the arc, in an anime that already has less action than what is expected of the block.
** The dropping of ''Manga/OnePiece'' in 2017. While there were some who glad to see one of the longer shows gone, many were frustrated that ''One Piece'' was dropped from the network ''again'', and for a show like ''Manga/TokyoGhoul''--which many felt had lost a ton of steam at that point. There were also fans who'd have preferred other long-running programs be dropped instead, most vocally ''Anime/DragonBallZKai'' or ''[[Manga/{{Naruto}} Naruto Shippuden]]''.
** While fans are in universal agreement that the block getting more hours is a good thing, the decision to add ''Manga/BlackClover'' to the block proved somewhat controversial -- aside from the fact that the manga is viewed as a ClicheStorm by its detractors, there's also the fact that the anime adaptation is seen as inferior by the fans of the manga, due to the anime being seen as too slow, taking 3 episodes to reach the second chapter. [[note]]Ironically, the manga often gets accused of being ''too'' fast-paced.[[/note]] Other people were more optimistic, pointing out that the dub is seen as an example of SugarWiki/SuperlativeDubbing, and that its success might lead to another shorter shonen a la ''Manga/MyHeroAcademia'' landing on the block. [[note]]Which did happen in May 2018, a mere five months after ''Black Clover'' first aired on the block.[[/note]]
** ''Sand Whale and Me'', a microseries directed by Creator/MamoruOshii and produced by Creator/ProductionIG for the block's 20th anniversary in 2017, is a mix of live-action and CG animation. Was this Toonami going against its promises of never airing live-action material, or was ''Sand Whale and Me'' an acceptable exception due to being a microseries made for a special occasion and not a full show?
%%** [adult swim]'s very own ''Gemusetto: Death Beat(s)'' quickly proved to be a big one when its addition to the block was announced in October 2020. Some people were excited for it and loved that something different than the usual was airing on the block, but some people ''really'' didn't want it there, saying that the show's ''very'' {{Mind Screw}}y nature and brand of strange and gross-out humor do not fit well with Toonami. This wasn't helped by the fact that the show got a lot of promotion compared to ''Manga/FireForce'' Season 2, which premiered on the same night the following month.

* Other:
** Toonami's length being cut down from 6-and-a-half hours to 3-and-a-half in February 2020 due to low ratings, essentially scaling the block back down to the same length it was when it was revived in 2012. Some were upset that Toonami was being cut in half in favor of more [adult swim] reruns, citing that the 2014 Month of Movies wasn't doing well due to low ratings and the lack of budget (notably, [[http://toonamifaithful.com/toonami-ratings-for-january-24th-2015/ on January 25th, 2015]], the lone episode of ''WesternAnimation/KingOfTheHill'' that aired after Toonami ended at 5:30 AM resulted in a ratings drop). Others thought that a smaller block with more premieres and less reruns would hold better ratings, noting that the Toonami crew has less space to worry about and wouldn't have to pad out the block with as many reruns. The only real agreement is that ''Anime/KillLaKill'' had essentially been screwed over due to no longer airing at 11:30 PM as planned, which was later proven wrong with ''KLK'' holding its own airing after ''DBZ Kai'' in the first half of the block.
** The insistence on Toonami being mainly action block. Most viewers got into it for the action shows anyway, but this being the only TV block that shows anime at all, some were upset about anime devoid of action not having a chance at being shown (to the point that ''Manga/DeathNote'', one of the more heavily requested shows for the block, is a non-action show). It doesn't help that the few instances of non-action shows airing on Toonami have been hit-or-miss (''Hamtaro'' and ''Tenchi Muyo GXP'' were universally agreed to not fit the block at all, while ''Bobobo-bo Bo-bobo'' and ''Space Dandy'' were more successful if not without detractors).
*** One especially major sticking point is {{Moe}} anime. While Moe anime has a big fanbase and viewership among more hardcore anime viewers, [[http://toonami.tumblr.com/post/59877272503/why-dont-you-play-more-moe-anime-instead-of-this Toonami however has made no bones]] about not playing Moe. Some will mention that this is likely because Moe tending to be an AudienceAlienatingPremise for general western viewers and casual fans, many of whom tend to be a big part of Toonami's main audience, being a GatewaySeries to anime and all.
** The business partnership between Creator/{{Funimation}} and Website/{{Crunchyroll}} and its impact on Toonami. While generally agreed to be amazing for the anime industry overall, Toonami fans are more divided. Some see the partnership as something that could hurt the block, as Funimation could end up prioritizing streaming over television, resulting in less shows for the block. Others argue that the partnership won't actually hurt Toonami, and in fact could be beneficial since they could have access to shows from Crunchyroll's catalogue (with requested favorites including ''Manga/MobPsycho100'' and ''Anime/NinetyOneDays'', the former of which was picked up by Toonami in October 2018).
** [[TwelveEpisodeAnime 1 or 2-Cour Anime]] vs. [[LongRunners Long Running]] {{Shonen}}: This one sprung up more after Toonami's block was reduced in length, resulting in arguments over rather the former or latter deserved more slots. The arguments became more intense in light of the acquisition of ''Manga/JoJosBizarreAdventure'', which means that at least ''five'' of the timeslots are taken up by LongRunners and only two others are available for shorter shows (one of which is reserved for reruns).
** {{Anime}} vs WesternAnimation: An argument over whether Toonami should air exclusively anime or rather slots should also be dedicated to WesternAnimation (whether they're Cartoon Network holdovers like ''WesternAnimation/ThunderCats2011'', ''WesternAnimation/SymBionicTitan'', and ''WesternAnimation/BewareTheBatman'', or are more adult-oriented material like the fifth season of ''WesternAnimation/SamuraiJack'').
** A third issue that has popped up since the 2014 Month of Movies is movies vs. [[MarathonRunning marathons]]. With holidays usually resulting in lower ratings, fans debate whether Toonami should simply marathon a show on the block or actually dedicate the night to airing a movie. Month of Movies 2014, which saw the chosen movies doing poorly for various reasons, intensified the arguments due to the block airing marathons much more frequently ever since.
** Whether Toonami should focus exclusively on newer shows from the 2010s, or should also dedicate space to older shows from the 2000s and 1990s. Many would argue that shows from the latter years would still fit Toonami (it helps that Toonami ''has'' aired older shows like ''Anime/SamuraiSeven'', ''Manga/BlackLagoon'', ''Anime/TengenToppaGurrenLagann'', and ''Anime/MichikoAndHatchin''), while others argue that Toonami should stay focused on newer shows since they generally do better in the ratings. This argument also extends to whether or not Toonami should bring back shows from the [adult swim] Action era like they did with ''Anime/EurekaSeven'' and ''Anime/SamuraiChamploo'', with some fan favorites from that era being ''Anime/CodeGeass'', ''Manga/DeathNote'', and the [[Anime/FullmetalAlchemist 2003]] ''Anime/FullmetalAlchemist'' [[Anime/FullmetalAlchemist anime]].
** Whether or not the block should ever re-air ''Manga/RurouniKenshin'', due to creator Creator/NobuhiroWatsuki's arrest for possession of child pornography. The "for" side cites their and the Toonami crew's own nostalgia (Gill Austin even wore a Kenshin cosplay to the 2017 SDCC panel, before the allegations were known), the separation of art and author, and ''Magazine/ShonenJump'' eventually allowing Watsuki to finish the Hokkaido Arc due to fan demand after the allegations were known. The "against" side cites Austin and [=DeMarco=] apparently saying the show left a bad taste in their mouth after his arrest, Misao's pedophilic attraction to Aoshi in the show (which is played as a joke), and the hypocrisy of allowing a pedophile to work for a children's magazine/on a network that is aimed at children during the day.
** [[https://www.youtube.com/watch?v=YHfJiZTtGEA Toonami's speech]] on racism and the UsefulNotes/{{Black Lives Matter movement}} caused a big stir. Aside from [[Administrivia/RuleOfCautiousEditingJudgment the usual discourse on the movement as a whole]], there was debate on whether the block itself is a suitable place for such a political statement. While Toonami has had multiple videos emphasizing equality before, this one ended up going viral on social media, thus getting picked up by mainstream media, amplifying the whole debate.
** Toonami continuing to co-fund original anime (such as ''Manga/{{Uzumaki}}'' and ''VideoGame/{{Shenmue}}'') is largely welcomed, but a portion of the base wishes they would stop funding original shows and use that money to acquire even more anime from distributors. It doesn't help that the block's most high profile shows to come of this have been ''Anime/IGPXImmortalGrandPrix'' and [[Anime/FLCLProgressiveAndAlternative Seasons 2 and 3]] of ''Anime/{{FLCL}}'', both of which are highly contested themselves.

The "against" side cites Gill and Jason apparently saying the show left a bad taste in their mouth after his arrest, Misao's pedophilic attraction to Aoshi in the show (which is played as a joke), and the hypocrisy of allowing a pedophile to work for a children's magazine/on a network that is aimed at children during the day.
** [[https://www.youtube.com/watch?v=YHfJiZTtGEA Toonami's speech on racism and the Black Lives Matter movement]] caused a big stir. Aside from the usual discourse on the movement as a whole, there was debate on whether the block itself is a suitable place for such a political statement. While Toonami has had multiple videos emphasizing equality before, this one ended up going viral on social media, thus getting picked up by mainstream media, amplifying the whole debate.

** Whether Toonami should focus exclusively on newer shows from the 2010s, or should also dedicate space to older shows from the 2000s and 1990s. Many would argue that shows from the latter years would still fit Toonami (it helps that Toonami ''has'' aired older shows like ''Anime/SamuraiSeven'', ''Manga/BlackLagoon'', ''Anime/TengenToppaGurrenLagann'', and ''Anime/MichikoToHatchin''), while others argue that Toonami should stay focused on newer shows since they generally do better in the ratings. This argument also extends to whether or not Toonami should bring back shows from the [adult swim] Action era like they did with ''Anime/EurekaSeven'' and ''Anime/SamuraiChamploo'', with some fan favorites from that era being ''Anime/CodeGeass'', ''Manga/DeathNote'', and the [[Anime/FullmetalAlchemist 2003]] ''Anime/FullmetalAlchemist'' [[Anime/FullmetalAlchemist anime]].

** [adult swim]'s very own ''Gemusetto: Death Beat(s)'' quickly proved to be a big one when its addition to the block was announced in October 2020. Some people were excited for it and loved that something different than the usual was airing on the block, but some people ''really'' didn't want it there, saying that the show's ''very'' {{Mind Screw}}y nature and brand of strange and gross-out humor do not fit well with Toonami. This wasn't helped by the fact that the show got a lot of promotion compared to ''Manga/FireForce'' Season 2, which premiered on the same night.

*** ''Iron-Blooded Orphans'' being picked for a marathon in late October 2016. [[note]]Marathons themselves are already quite divisive, as described down below.[[/note]] While many fans liked that the anime was getting more exposure on behalf of Toonami, choosing the Dort Colonies arc had a polarizing reaction. Fans were glad it wasn't yet ''another'' start-in-the-beginning marathon that Toonami is known for, thus allowing people to rewatch character development, but said arc is also controversial due to a noticeable lack of Gundam fights in much of the arc of an anime that already has less action.

** ''Sand Whale and Me'', a microseries directed by Creator/MamoruOshii and produced by Creator/ProductionIG for the block's 20th anniversary, is a mix of live-action and CG animation. Is this Toonami going against its promises of never airing live-action material, or is ''Sand Whale and Me'' an acceptable exception due to being a microseries made for a special occasion and not a full show?
** So far, [adult swim]'s very own ''Gemusetto: Death Beat(s)'' is a big one. Some people are excited for it and love that something different than the usual is airing on the block, but some people ''really'' don't want it there, saying that the show's very MindScrew nature and it's brand of strange and gross-out humor does not fit well with Toonami. This isn't helped by the fact that the show got a lot of promotion compared to Manga/FireForce Season 2, which premiered on the same night.

** Toonami's length being cut down from 6-and-a-half hours to 3-and-a-half due to low ratings, essentially scaling the block back down to the same length it was when it was revived in 2012. Some are upset that Toonami is being cut in half in favor of more [adult swim] reruns, citing that the 2014 Month of Movies wasn't doing well due to low ratings and the lack of budget (notably, [[http://toonamifaithful.com/toonami-ratings-for-january-24th-2015/ on January 25th, 2015]], the lone episode of ''King of the Hill'' that aired after Toonami ended at 5:30 AM resulted in a ratings drop). Others think that a smaller block with more premieres and less reruns would hold better ratings, noting that the Toonami crew has less space to worry about and won't have to pad out the block with as many reruns. The only real agreement is that ''Kill la Kill'' had essentially been screwed over due to no longer airing at 11:30 PM as planned, which was later proven wrong with KLK holding its own airing after DBZ Kai in the first half of the block.
** The insistence on Toonami being mainly action block. Most viewers got into it for the action shows anyway, but this being the only TV block that shows anime at all, some are upset about anime devoid of action not having a chance at being shown (to the point that one of [[Manga/DeathNote the more heavily requested shows for the block]] is a non-action show). It doesn't help that the few instances of non-action shows airing on Toonami have been hit-or-miss (''Hamtaro'' and ''Tenchi Muyo GXP'' were universally agreed to not fit the block at all, while ''Bobobo-bo Bo-bobo'' and ''Space Dandy'' were more successful if not without detractors).
*** One especially major sticking point is {{Moe}} {{anime}}. While Moe anime has a big fanbase and viewership among more hardcore anime viewers, [[http://toonami.tumblr.com/post/59877272503/why-dont-you-play-more-moe-anime-instead-of-this Toonami however has made no bones]] about not playing Moe. Some will mention that this is likely because moe tending to be an AudienceAlienatingPremise for general western viewers and casual fans, many of whom tends to be a big part of Toonami’s main audience, being a GatewaySeries to anime and all.
** The business partnership between Funimation and Website/{{Crunchyroll}} and its impact on Toonami. While generally agreed to be amazing for the anime industry overall, Toonami fans are more divided. Some see the partnership as something that could hurt the block, as Funimation could end up prioritizing streaming over television, resulting in less shows for the block. Others argue that the partnership won't actually hurt Toonami, and in fact could be beneficial since they could have access to shows from Crunchyroll's catalogue (with currently requested favorites being ''Manga/MobPsycho100'' and ''Anime/NinetyOneDays'').
** [[TwelveEpisodeAnime 1 or 2-Cour Anime]] vs [[LongRunners Long Running]] {{Shonen}}: This one sprung up more after Toonami's block was reduced, resulting in arguments over rather the former or latter deserved more slots. The arguments got more intense in light of the acquisition of ''Manga/JoJosBizarreAdventure'', which means that at least ''five'' of the timeslots are taken up by LongRunners and only two others are available for shorter shows (one of which is reserved for reruns).

** Whether Toonami should focus exclusively on newer shows from the 2010s, or should also dedicate space to older shows from the 2000s and 1990s. Many would argue that shows from the latter years would still fit Toonami, (it helps that Toonami ''has'' aired older shows like ''Samurai 7'', ''Black Lagoon'', ''Tengen Toppa Gurren Lagann'', and ''Michiko & Hatchin''), while others argue that Toonami should stay focused on newer shows since they generally do better in the ratings. This argument also extends to whether or not Toonami should bring back shows from the [adult swim] Action era like they did with ''Eureka Seven'' and ''Samurai Champloo'', with some fan favorites from that era being ''Code Geass'', ''Death Note'', and the 2003 ''Fullmetal Alchemist'' anime.
** Whether or not the block should ever re-air ''{{Manga/Rurouni Kenshin}}'', due to creator Nobuhiro Watsuki's arrest for possession of child pornography. The "for" side cites their and the Toonami crew's own nostalgia (Gill even wore a Kenshin cosplay to the 2017 SDCC panel, before the allegations were known), the separation of art and author, and ''Magazine/ShonenJump'' eventually allowing Watsuki to finish the Hokkaido Arc due to fan demand after the allegations were known. The "against" side cites Gill and Jason apparently saying the show left a bad taste in their mouth after his arrest, Misao's pedophilic attraction to Aoshi in the show (which is played as a joke), and the hypocrisy of allowing a pedophile to work for a children's magazine/on a network that is aimed at children during the day.

** Toonami continuing to co-fund original anime (such as {{Manga/Uzumaki}} and {{VideoGame/Shenmue}}) is largely welcomed, but a portion of the base wishes they would stop funding original shows and use that money to acquire even more anime from distributors. It doesn't help that the block's most high profile shows to come of this have been Anime/IGPXImmortalGrandPrix and Seasons 2 and 3 of {{Anime/FLCL}}, both of which are highly contested themselves.

Despite being a well-beloved block, Creator/{{Toonami}} [[BrokenBase can have some disagreements among its fans.]]

** ''Anime/TenchiMuyoGXP''. Some enjoyed it for being an overall fun show following in the footsteps [[Anime/TenchiMuyoRyoOhki of]] [[Anime/TenchiUniverse its]] [[Anime/TenchiInTokyo predecessors]], while others hated it for being a non-action show airing on Toonami, an action-oriented block (despite the fact that the ''Anime/TenchiMuyo'' series in general isn't an action-oriented series). Unfortunately, the latter side seems to have more prevalence, as the show tanked in ratings to the point of [[ScrewedByTheNetwork being moved down to 3:00 AM]] (though in all fairness, GXP did manage to finish its run and air all 26 of its episodes without getting taken off the lineup), and at least for a time, fans considered it unlikely that any other shows that put less emphasis on action will air on the block.
** ''WesternAnimation/ThunderCats2011'' and ''WesternAnimation/SymBionicTitan''... or rather, the fact that they were added to the lineup in the first place. Anime fans insist that Toonami should stick exclusively to anime and that their acquisition of western shows is a form of NetworkDecay (these same fans forget that Toonami was never meant to be an anime-only block in the first place; the original 1997 lineup was almost entirely Western toons, and even the anime-dominated "classic" Toonami of the early 2000s included the likes of ''WesternAnimation/ThunderCats1985'', ''WesternAnimation/ReBoot'', almost all of the Franchise/{{DCAU}} shows, ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'', and even ''WesternAnimation/ThePowerPuffGirls'' in its mix.). Others are either happy about or don't really mind the addition of western animation. We can also add ''WesternAnimation/StarWarsTheCloneWars'', ''WesternAnimation/BewareTheBatman'', and ''WesternAnimation/SamuraiJack'' to the list. Interestingly, the more adult oriented final season of ''Samurai Jack'' mostly averted this, with audience reaction and ratings being rather positive.
** When Toonami came back in 2012, ''Anime/CowboyBebop'' was one of the shows that was previously airing on Creator/AdultSwim and carried over to Toonami. When its run ended, it was taken off along with ''Manga/DeadmanWonderland'' and replaced by ''Anime/SamuraiSeven'' and ''Anime/EurekaSeven''. However, when the block expanded to 6 hours, it was brought back to the lineup. While some fans don't really mind, other fans are sick of seeing the show to the point where they actually want it to be taken off (it was aired nearly non-stop with few breaks since ''September 2001''); the latter group got their wish late in 2014. Unfortunately, the removal of ''Bebop'' flipped the tables, satisfying the people who wanted the show off, but also pissing off the fans who were perfectly fine with it.
*** After a short, incomplete stint in 2015, it returned two years later, eventually completing the entirety of its HD rerun. But then Toonami made the decision to start it [[HereWeGoAgain right from the beginning, without a break]]. Some thought it should remain off of Toonami so the audience could grow to miss it again, while others didn't really care, probably because a lot of them don't watch the rerun to begin with.
** Debates on whether ''LightNovel/SwordArtOnline'' would make it to Toonami were full with this. When the sub aired, there was considerable demand at first and fans have said it’s a good GatewaySeries, but the detractors got more vocal as the series went on (especially in regards to the Fairy Dance arc), and accused it of being heavy on "[[PanderingToTheBase Otaku pandering]]" and WishFulfillment, which wouldn’t fit well with Toonami’s emphasis on being a gateway drug to the anime medium. Ultimately, when it was time for the decision, [[CriticalBacklash the block’s creators thought that]] [[http://toonami.tumblr.com/post/54263109126/do-you-have-any-concerns-about-the-incest-subplot-in the negative aspects]] [[http://toonami.tumblr.com/post/54258600250/someone-is-gonna-ask-this-anyway-so-i-figured-i-get-it weren’t a big deal]]. The show would be a ratings success regardless, and would lead to the advent of more Creator/{{Aniplex}} shows airing on the block, including SAO's second season two years later. They did mention however that SAO’s SeasonalRot [[http://toonami.tumblr.com/post/54261782321/is-the-reason-youre-telling-people-to-wait-until-titan is one of the reasons why]] [[http://toonami.tumblr.com/post/54259682512/have-you-all-had-a-chance-to-watch-any-of-attack-on fans shouldn’t rush to request a show]] [[http://toonami.tumblr.com/post/54259923178/what-are-the-chances-of-getting-attack-on-titan-when until they see how a show "turns out"]], as mentioned when asked if ''Manga/AttackOnTitan'', which at the time was another largely requested show, would eventually air on Toonami. [[note]]Attack on Titan would of course eventually be a Toonami show a year later.[[/note]] With the SAO anime (and the franchise as a whole) becoming even more dividing as it gone on, it should surprise no one that it remained a Broken Base all the way through all three parts of Season 3, especially since it usually gets one of the prime timeslots on the block.
** ''Kick-Heart'', a kickstarter-funded 15-minute short produced by Production I.G. that was aired during Labor Day weekend in 2014, premiering [[MoodWhiplash right after]] ''Evangelion 2.22'', and again on November 2nd of that year along with ''King Star King'' and ''WesternAnimation/KorgothOfBarbaria'' as Daylight Savings Time filler. Reception has so far been mixed, with some liking the surreal artstyle and quality which greatly contrasts that of the shows in Toonami's lineup and resembles the type of shows that air on regular Creator/AdultSwim, while others despised it for the very same reasons.
** ''WesternAnimation/KingStarKing'' suffered a brutal backlash when it was played during the 2013 DST Hour alongside ''WesternAnimation/KorgothOfBarbaria'' and ''Kick-Heart'', to the point where Toonami's showrunner ran a Twitter poll asking whether they should replay the DST Hour again the next year or do something experimental. The verdict? [[https://twitter.com/Clarknova1/status/397164256984330241 "Experimental by a huge margin. As long as it's NOT King Star King!"]] There were a few people here and there who did like King Star King, but they were greatly outnumbered by those who didn't.
** ''Anime/SpaceDandy'' is mostly a welcome addition to the block and is AdoredByTheNetwork to the extent that Cartoon Network made a special deal to air the dub hours before the Japanese saw their version of the episodes, but some fans are still miffed that it's a comedy in the middle of an action block (when in fact the show has lots of action anyway, and it sometimes takes on genres other than comedy), and the lack of continuity is annoying to some people expecting that in anime. Especially given how it was heavily advertised as being from the creators of ''Anime/CowboyBebop'', which while episodic and having comedy elements also had serious stories and firm continuity. [[spoiler:Until the last few episodes showed that ''Space Dandy'''s apparent NegativeContinuity actually had an in-universe reason.]]
** ''WesternAnimation/BewareTheBatman'', much like the above-mentioned western shows, has not been well-received by anime fans ever since Toonami started airing the show at 3:00 AM, replacing ''Ghost in the Shell: Stand Alone Complex''. What really struck a match, however, was the decision to have the show switch timeslots with ''Manga/BlackLagoon'', which was still premiering its second season at 2:30, in order to place priorities on the unaired episodes. Some thought Toonami had its priorities set in the right place (they had not actually ''premiered'' a western show before, while ''Black Lagoon'' was pushing 10 years old at that point), while others were upset that an anime show that was still premiering was being pushed down to 3:00, the same timeslot that ''Tenchi Muyo! GXP'' was [[ScrewedByTheNetwork relegated to due to low ratings]].
** The base became even further divided in the span of three weeks when ''Anime/HellsingUltimate'' debuted behind ''Beware the Batman'', making 2:30-3 one of the most jarring switches between shows in the block's history, (going from the {{Bowdlerize}}d action in ''Beware'', complete with FamilyFriendlyFirearms, to Hellsing, with scenes bordering on outright {{Gorn}}). And then the ''Beware'' license was written off with less than a week's warning. Fans of ''Hellsing'' did not appreciate their show being preempted for a ''Beware the Batman'' marathon, pointing out the ratings would dip steadily during the night and then rise considerably for Hellsing Ultimate. Supporters countered that Beware had been ScrewedByTheNetwork once before and airing the remaining episodes, even in a mini-marathon, was making the best of a bad situation.
** Toonami's first announced acquisition from Creator/SentaiFilmworks being ''Manga/AkameGaKill''. Some think that the show is of poor quality and that Toonami could've made a better choice. Others are simply glad that Toonami has ''finally'' picked up a show from Sentai Filmworks, something that many thought would never happen. Somewhat alleviated with the later announcement that ''Manga/{{Parasyte}}'' was also picked up for airing.
** An example going back to Toonami's days on Cartoon Network is ''Manga/BoboboboBobobo'', a show that, while technically falling under the action genre, was completely balls-to-the-wall insane and thus deemed by some as a questionable choice for the block. The show was even brought up in an early episode of Toonami Pre-Flight discussing Toonami's great failures. It was high up on the official Facebook page's considerations for Toonami's failures, yet Jason [=DeMarco=] said that there just as many people who want to see the show aired again.
** Unexpectedly for something considered the long-anticipated return of a Toonami staple, ''Anime/MobileSuitGundamIronBloodedOrphans'' received a somewhat mixed reception from viewers. One party likes the show and are glad that ''Gundam'' is finally back on Toonami, while the other dislikes it for being "too slow" and not having enough action sequences compared to the other shows on the block. This became even more intense with IBO's second season, which is extremely divisive even among fans of the show.
*** ''Anime/MobileSuitGundamIronBloodedOrphans'' being picked as a late-October marathons. [[note]]Marathons themselves are already quite divisive, as described down below[[/note]] While many fans like that the anime is getting more exposure on behalf of Toonami, choosing the Dort Colonies Arc had a polarizing reaction. While fans are glad that it's not yet ''another'' start-in-the-beginning marathon that they always do, and allows for people to re-watch character development, the Arc is also controversial, due to a noticeable lack of Gundam fights in much of the Arc of an anime that already has less action.
** The dropping of ''One Piece'' in 2017. While there are some who are glad to see one of the longer shows gone, many are frustrated that ''One Piece'' is dropping from the network ''again'', and for a show like ''Manga/TokyoGhoul'' which many feel has lost a ton of steam. There are also fans who'd have preferred other long running programs be dropped instead, most vocally ''Kai'' or ''Shippuden''.

** While fans are in universal agreement that the block getting more hours is a good thing, the decision to add ''Manga/BlackClover'' to the block has been somewhat controversial - aside from the fact that the manga is viewed as a ClicheStorm by its detractors, there's also the fact that the anime adaptation is seen as inferior by the fans of the manga, due to the anime being seen as too slow, taking 3 episodes to reach the second chapter. [[note]]ironically, the manga often gets accused of being ''too'' fast-paced[[/note]] Other people are more optimistic, pointing out that the dub is seen as an example of SugarWiki/SuperlativeDubbing, and it's success might lead to another shorter shounen a la ''Manga/MyHeroAcademia'' landing on the block.

** Whether or not the block should ever re-air ''{{Manga/Rurouni Kenshin}}'', due to creator Nobuhiro Watsuki's arrest for possession of child pornography. The "for" side cites their and the Toonami crew's own nostalgia (Gill even wore a Kenshin cosplay to the 2017 SDCC panel, before the allegations were known), the separation of art and author, and ''{{Creator/Shonen Jump}}'' eventually allowing Watsuki to finish the Hokkaido Arc due to fan demand after the allegations were known. The "against" side cites Gill and Jason apparently saying the show left a bad taste in their mouth after his arrest, Misao's pedophilic attraction to Aoshi in the show (which is played as a joke), and the hypocrisy of allowing a pedophile to work for a children's magazine/on a network that is aimed at children during the day.
** Toonami's [[https://www.youtube.com/watch?v=YHfJiZTtGEA speech]] on racism and the Black Lives Matter movement caused a big stir.

Is this Toonami going against its promises of never airing live-action material, or is ''Sand Whale and Me'' an acceptable exception due to being a microseries made for a special occasion and not a full show?

** So far, [adult swim]'s very own ''Gemusetto: Death Beat(s)'' is a big one. Some people are excited for it and love that something different than the usual is airing on the block, but some people ''really'' don't want it there, saying that the show's very MindScrew nature and it's brand of strange and gross-out humor does not fit well with Toonami.

** ''WesternAnimation/ThunderCats2011'' and ''WesternAnimation/SymBionicTitan''... or rather, the fact that they were added to the lineup in the first place. Anime fans insist that Toonami should stick exclusively to anime and that their acquisition of western shows is a form of NetworkDecay (these same fans forget that Toonami was never meant to be an anime-only block in the first place; the original 1997 lineup was almost entirely Western toons, and even the anime-dominated "classic" Toonami of the early 2000s included the likes of ''WesternAnimation/SupermanTheAnimatedSeries'', ''WesternAnimation/BatmanBeyond'', ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'', and even ''WesternAnimation/ThePowerPuffGirls'' in its mix.). Others are either happy about or don't really mind the addition of western animation. We can also add ''WesternAnimation/StarWarsTheCloneWars'', ''WesternAnimation/BewareTheBatman'', and ''WesternAnimation/SamuraiJack'' to the list. Interestingly, the more adult oriented final season of ''Samurai Jack'' mostly averted this, with audience reaction and ratings being rather positive.

** Whether Toonami should focus exclusively on newer shows from the 2010s, or should also dedicate space to older shows from the 2000s. Many would argue that shows from the latter years would still fit Toonami, (it helps that Toonami ''has'' aired older shows like ''Samurai 7'', ''Black Lagoon'', ''Tengen Toppa Gurren Lagann'', and ''Michiko & Hatchin''), while others argue that Toonami should stay focused on newer shows since they generally do better in the ratings. This argument also extends to whether or not Toonami should bring back shows from the [adult swim] Action era like they did with ''Eureka Seven'' and ''Samurai Champloo'', with some fan favorites from that era being ''Code Geass'', ''Death Note'', and the 2003 ''Fullmetal Alchemist'' anime.

** Toonami's length being cut down from 6-and-a-half hours to 3-and-a-half due to low ratings, essentially scaling the block back down to the same length it was when it was revived in 2012. Some are upset that Toonami is being cut in half in favor of more [adult swim] reruns, stating that the block in general gets more ratings than [adult swim]'s other programming (notably, [[http://toonamifaithful.com/toonami-ratings-for-january-24th-2015/ on January 24th]], the lone episode of ''King of the Hill'' that aired after Toonami ended at 5:30 AM resulted in a ratings drop). Others think that a smaller block with more premieres and less reruns would hold better ratings, noting that the Toonami crew has less space to worry about and won't have to pad out the block with as many reruns. The only real agreement is that ''Kill la Kill'' had essentially been screwed over due to no longer airing at 11:30 PM as planned, which was later proven wrong with KLK holding its own airing after DBZ Kai in the first half of the block.

** [[AprilFools April 1st, 2017]] marked a bad day for ''WesternAnimation/SamuraiJack'' fans. When the fourth episode was set to air, and only four weeks in on the series' revival after a 12 year cancellation, ''WesternAnimation/RickAndMorty'' had a legitimate season 3 episode premiere as part of the yearly April Fool's joke that Creator/AdultSwim is known for causing stirs with. The problem is that Rick and Morty's episode was then put on marathon for ''four hours,'' overwriting the rest of Adult Swim's schedule during the time and consequently both Samurai Jack and ''Anime/DragonBallSuper'' for the weekend. When Toonami finally started up an hour late, they had the foresight to have Tom and Sara apologize for the two shows would be delayed to the following weekend, but it wasn't enough to prevent a FandomRivalry and people online from going full SnarkBait for the weeks thereafter.

** If this can be applied to a show, ''Anime/TenchiMuyoGXP'' fits the bill. Some enjoyed it for being an overall fun show following in the footsteps [[Anime/TenchiMuyoRyoOhki of]] [[Anime/TenchiUniverse its]] [[Anime/TenchiInTokyo predecessors]], while others hated it for being a non-action show airing on Toonami, an action-oriented block (despite the fact that the ''Anime/TenchiMuyo'' series in general isn't an action-oriented series). Unfortunately, the latter side seems to have more prevalence, as the show tanked in ratings to the point of [[ScrewedByTheNetwork being moved down to 3:00 AM]] (though in all fairness, GXP did manage to finish its run and air all 26 of its episodes without getting taken off the lineup), and at least for a time, fans considered it unlikely that any other shows that put less emphasis on action will air on the block.
