History YMMV / OsomatsuSan

*** This criticism of Choromatsu has reared it's ugly head again following the release of [[TheMovie The Movie.]] [[spoiler:His desire to stay in the memory world to gawk at high-school Totoko and junior-high Nyaa-chan can come off as incredibly creepy to some fans. Granted Jyushimatsu calls him out on it immediately, but the [[UnfortunateImplications unfortunate implication]] is still there.]]

** Jyushimatsu because of his childlike attitude, [[NiceGuy sweet personality]], and HandHidingSleeves.

** Choromatsu got "devastated" when he learned that his idol [[spoiler:was once married, has a child, [[ArsonMurderAndJaywalking and is falling in love with his shit eldest brother]]]]. This should have been a TearJerker, but becomes hilarious when one knows that a gossip magazine revealed in 2016 that ''Choromtsu'''s voice actor, Creator/HiroshiKamiya, [[spoiler:had been married for serveral years and had a child already]].

** From the movie, Ichimatsu's high school friend Yanagida. Being one of the few actively positive influences in his life and a somewhat convntionally attractive character by the show's standards, Yanagida quickly picked up a fanbase. He got so popular that he made the top seven in a series official poll, only a year after he debuted. He's often seen as Ichimatsu's "Atsushi" of sorts.

* SomeAnvilsNeedToBeDropped: From "Choromatsu Rising": If you're going to do something, just go out and ''do it''. Don't announce your plans and make a big fuss of them if you aren't going to work towards your goals, and if you tell everyone what you plan on doing without having any actions to back it up, it makes you complacent and wastes everyone's time. Waffling on your goals does the same thing.

** The fact that their first idea was a HotterAndSexier HighSchoolAU (with some romcom thrown in for good measure) makes the 2016 debut of high school romcom ''Manga/TheQuintessentialQuintuplets'', a series about lazy ''quin''tuplet girls getting help studying from their beleaguered neighbor, a little too familiar. The fact that the male lead has a somewhat Matsu-like hairstyle doesn't help. It also coincidentally resembles a common fanon concept where [[http://danbooru.donmai.us/posts/2232633 five of the brothers are cute girls]], while one (usually Choromatsu or Osomatsu) is male and has to put up with his sisters' screwball antics.

* AlternateJokeInterpretation / HilariousInHindsight: At the time the first Mr Flag episode aired, Choromatsu's "OBAMA?!" yell was funny just because of the delivery. It was justified in that Hatabou knowing the US President was surprising. Due to AnimationLeadTime, the English dub came out years after Obama had left the office and quietly retired--Hatabou being contacted by a world leader makes much more sense than being contacted by a random former celebrity, making Choromatsu's outburst that much more confused.

** ''Osomatsu-san'' and ''Anime/{{Doraemon}}'' fans tend to go hand-in-hand, at least in Japan. This has a lot to do with both ''Doraemon'' and [[Manga/OsomatsuKun the previous series]] coming out around the same time, too.

** Choromatsu was right to worry about how the cast handled "''Manga/Osomatsu-kun'' Returns"-- because of the episode's controversial nature and some old fashioned copyright infringement, the episode has not only been pulled from Japanese streaming websites and Crunchyroll, but also from its DVD/BD release.

** Episode 10 was well received in Japan due to being a reprise of the iconic Iyami-Chibita team-up and having a tone similar to that of ''-Kun''. Its reception in the Western fandom was more... polarized, to be blunt, particularly among those who found the episode transphobic.

** The tone and humor of ''-San'' is fairly different from that of ''-Kun'', meaning that many who read[=/=]saw ''-Kun'' first favor the first series. Those people also tend to prefer the characterizations of Chibita and Iyami in ''-Kun'', since they were given more screentime to really stretch out their characters. Some watchers are also hesitant with ''-San'' because they're afraid of the legacy of the show upstaging ''-Kun'' entirely.

* CharacterRerailment: Season 2 started matching characters up to their ''-Kun'' roots:

** Thanks to the ColbertBump the show gave to ''-Kun's'' manga, it's popular to depict some of the manga's plots as events the Matsunos remember. Of particular note is Choromatsu having nightmares about the events of "Osomatsu-kun in 40 years" and Tougou from "The Terrifying Lodger" coming back into Osomatsu's life.

** ''Osomatsu-san'' and ''Anime/{{Doraemon}}'' fans tend to go hand-in-hand, at least in Japan. This has a lot to do with both ''Doraemon'' and [[Manga/OsomatsuKun the previous series]] coming out around the same time, too.

** Choromatsu was right to worry about how the cast handled "''Manga/OsomatsuKun'' Returns"-- because of the episode's controversial nature and some old fashioned copyright infringement, the episode has not only been pulled from Japanese streaming websites and Crunchyroll, but also from its DVD/BD release.

** The fact that Yoichi Fujita served as director for the show, given that the [[{{Manga/Gintama}} other show he was best known for directing]] had an episode where expies of the ''-Kun'' era brothers squared off against the Odd Jobs gang.

** The TitleCharacter possibly got them all beat. He gets paired up with his brothers, [[FoeYay Iyami, Chibita, Tougou (from the 'Kun' verse)]], Atsushi, Totoko, and to a lesser extent, Nyaa. [[spoiler:Ironically, the canon actually spent an episode to explore the last one [[ShipSinking only to tear it down]] [[AntiClimax in a matter of 30 seconds]]]].

** Iyami's "SHEEEH!", which had been a meme previously in the ''-Kun'' era and got a reinsurgence thanks to this series.

** Nyaa-chan's boasting about her getting a hot and smart fiance in "Totoko's Big Panic" rings a little sad come Season 3, where [[spoiler:she's not only broken up with the guy, but also left to raise his child alone]].

** Choromatsu got "devastated" when he learned that his idol [[spoiler:was once married, has a child, [[ArsonMurderAndJaywalking and is falling in love with his shit eldest brother]]]]. This should have been a TearJerker, but becomes hilarious when one knows that a gossip magazine revealed in 2016 that ''Choroamtsu'''s voice actor, Creator/HiroshiKamiya, [[spoiler:had been married for serveral years and had a child already]].

** Nyaa-chan's boasting about her getting a hot and smart fiance in "Totoko's Big Panic" rings a little sad come season 3, where [[spoiler:She's not only broken up with the guy, but also left to raise his child alone]].

** Ichimatsu instigates this twice in "We Caught a Cold". First, he decides to transfer his cold to Osomatsu (for blowing their money on pachinko) by [[ForcefulKiss French kissing]] him. Then, [[DoesThisRemindYouOfAnything he makes his brothers beg for cold compresses]] when he's feeling better.

** Nyaa Hashimoto only appears in a handful of scenes and doesn't even get many actual speaking lines, but she's still just as loved by the fans and often gets fanart. The second OP features Nyaa together with other secondary characters, but she doesn't show up in person until the penultimate episode of Season 1.

** In Japan, Atsushi is one of the more popular one shot characters despite only appearing in one segment, being Todomatsu's successful young friend who just so happens to look a little similar to the Matsunos, and is shipped with just about every member of the main cast.

** Nyaa-chan's [[spoiler:former fiance]] isn't very well liked from those that rather ship her with [[ShipTease Choromatsu,]] [[CrackPairing Ichimatsu]] or [[LesYay Totoko.]]

** As of the second cour, Jyushimatsu. While he is by no means losing popularity, his increased presence in some of the skits have led some to accuse him of being either overused or used uncreatively, which Iyami even lampshades in "Iyami's School".

** The idea of shipping the Matsuno brothers with [[IncestYayShipping each other]] is a very divisive topic in the Western fandom. The disagreement over said ships has also lead to fans being either disgusted or amused by Ichimatsu's more questionable behavior towards his brothers in the second cour (such forcibly kissing Osomatsu and later [[DoesThisRemindYouOfAnything taunting his brothers with towels]] in "We Caught a Cold").

** Episode 16 had those who liked it due to developing Ichimatsu and Karamatsu's characters in the second half, and those who felt the episode was just one long string of HoYay jokes (made worse by the main characters' biological relationship). The idol segment during the first half also drew criticisms that the second cour suffers from an over-reliance on AlternateUniverse plots in lieu of actual CharacterDevelopment.

** Nyaa Hashimoto only appears in a handful of scenes and doesn't even get many actual speaking lines, but she's still just as loved by the fans and often gets fanart.

** The TitleCharacter possibly got them all beat. He gets paired up with his brothers, [[FoeYay Iyami, Chibita, Tougou (from the 'Kun' verse)]], Atsushi, Totoko, and to a lesser extent, Nyaa. [[spoiler:Ironically, the last one is the only one that the canon actually explores [[ShipSinking and tears down]]]].

* FunnyAneurysmMoment: The very beginning of "The Melancholy of Osomatsu" is funny the first time, since Osomatsu imagining that his brothers are playing cards with him (spot-on voice imitation of them included) is the whole punchline. After you've watched [[DarkerAndEdgier "Sanematsu-san"]], it can be a bit chilling instead, since it's almost the same thing but PlayedForDrama.
* GermansLoveDavidHasselhoff: The anime in general had been very popular in the West LONG before it got licensed by Viz.
** Episode specific, “Iyami’s Counterattack” was liked better outside of Japan, where it placed pretty low on "favorite episode" polls.

** Osomatsu's "I love you, Reika!" line from all the way back in Season 1 becomes this in Season 3, where a whole episode is devoted to [[spoiler:Osomatsu and Nyaa-chan falling in love with each other, but never managing to commit]].

** The TitleCharacter possibly got them all beat. He gets paired up with his brothers, [[FoeYay Iyami, Chibita, Tougou (from the 'Kun' verse)]], Atsushi, Totoko, and in a lesser extent Nyaa, [[spoiler:which is [[ShipSinking what the canon actually explores at one point]]]].

** On Website/NicoNicoDouga, ﾔﾊﾞｲﾔﾊﾞｲﾔﾊﾞﾔﾊﾞｰｲ. [[note]]A fan made [[http://www.nicovideo.jp/watch/sm27648644 an otoMAD of the first OP, featuring Ichimatsu's "oh no, oh no" dance at the 0:37 mark.]] Commenters took a liking to it, leading to the comment above being posted to ''any'' video featuring the OP.[[/note]]

** Iyami's "SHEEEH!".

** Chorgus. [[note]] Nickname for Choromatsu, courtesy of twitter. [[/note]]

* {{Moe}}:
** Because of Jyushimatsu's childlike attitude, [[NiceGuy sweet personality]], and HandHidingSleeves, some viewers consider him to be this.
** Ichimatsu, while not being the most pleasant person around, actually invokes this in audience members do to being the most "[[NoSocialSkills relatable]]" and because of his huge fondness for cats.

** To some, all six brothers, at least to some extent. Every fan's got a favorite for this very reason.

** Fans who ship Karamatsu and Choromatsu platonically or [[IncestYayShipping more so,]] they DO NOT let go of the fact in episode 4, where Choromatsu told Karamatsu he would take care of him, if they couldn't remain in their house.

** With Karamatsu/Choromatsu, there's a good chance, Jyushimatsu/the country girl would pop up in the fanworks.

** The TitleCharacter possibly got them all beat. He gets paired up with his brothers, [[FoeYay Iyami, Chibita, Tougou (from the 'Kun' verse)]], Atsushi, Totoko, and in a lesser extent Nyaa.

** There's also lots of ships for Matsus with different identities, for example Inspector Choromatsu from "Calming Detective" with Inspector Ichimatsu from episode 17.

** Thanks to early descriptions of episode 16, different variations on Ichimatsu stealing Karamatsu's glasses and the aftermath of someone discovering him. "The Ichimatsu Incident" is basically this plot, scene for scene.

** Even from the previous anime series (also animated by Studio Pierrot) we get this. 1988 Series Episode 5 is titled 'Chibita's Love. A Flower that Withers'. Guess what happens in Episode 15.

** Karamatsu [[spoiler: punching Osomatsu for [[KickTheDog hitting Jyushimatsu and getting in the latter's face in a fit of anger]]]] in Episode 24. What Osomatsu does in itself classifies as this, but at least you see it coming, since his frustration was clearly building up during the skit. Karamatsu's outburst on the other hand was completely out of the blue, [[BewareTheNiceOnes especially coming from him]].

* TheyWastedAPerfectlyGoodPlot: Episode 24 has [[spoiler:Choromatsu getting a new job and moving out, the brothers gradually moving out and trying to live new lives, and it ends with a Cliffhanger as Osomatsu receives the letter that Choromatsu had written earlier]], making it one of the biggest {{Tear Jerker}}s in the series. Then comes episode 25 where all of that gets dropped in 2 minutes and it just becomes another gag episode. However, according to WordOfGod, [[TrollingCreator this plot was meant to be wasted all along]]. That being said, fans weren't as unforgiving when the stunt was repeated with [[spoiler: the "Spring"/"Osomatsu-san in Hell" two-parter]] in season 2; part of it was because of remembering what happened the last time, and part of it was because the wacky second half was kicked off by outside interference rather than deliberate sabotage.

** Most fans did ''not'' expect the F6 designs from the original version of Episode 1 to show up ten episodes later without warning, especially since by then the episode had already been taken down from stream sites. Even more so when they appeared in episode 3.5 and "Matsuno Matsunan".

* WhatDoYouMeanItsNotForKids: While the original manga is a [[ShonenDemographic Shonen]] and the characters in ''-San'' are still drawn as wacky and cartoonish as it gets, the anime airs late at night in Japan and most episodes have enough sex/nudity jokes that wouldn't let it pass as a kid's show. The CaughtWithYourPantsDown scene in episode 13 [[http://www.animenewsnetwork.com/interest/2016-02-09/bpo-publishes-viewer-complaint-about-man-catching-brother-masturbating-in-anime/.98499 actually caused some problems with censors because of this]].

** Jyushimatsu falls into this pretty hard in Episode 9. [[spoiler: The one time he actually falls in love with someone, and he gets rejected because she has to leave him. He's so heartbroken by this that he just [[OOCIsSeriousBusiness breaks down in tears]]]]. [[TearJerker Awww...]]
** Karamatsu, especially after episode 5. It didn't help that [[AllThereInTheManual supplementary material]] later revealed that he dislikes himself and uses his "cool guy" persona as a coping mechanism.

** Episode 16 had those who liked it due to developing Ichimatsu and Karamatsu's characters in the second half, and those who felt the episode was just one long string of HoYay jokes (made worse by the [[IncestIsRelative main characters' biological relationship]]). The idol segment during the first half also drew criticisms that the second cour suffers from an over-reliance on AlternateUniverse plots in lieu of actual CharacterDevelopment.

** On the slash/[[IncestIsRelative incest]] side of things: on Pixiv, two of the most popular ships seem to be Ichimatsu/Karamatsu and Osomatsu/Choromatsu.

* SecondSeasonDownfall: In stark contrast to the overwhelming SleeperHit success that was the first season, the second season experienced considerably less fanfare. This is generally attributed to the more mean-spirited tone of the second season's episodes compared to the first's. While it's generally agreed that there was a drop in quality from the first, whether the season was still good in its own right or a veritable bomb is a topic of contention.
