History YMMV / KadoTheRightAnswer

* FanPreferredCouple: zaShunina x Shindou seems to be this. [[spoiler: A ''Newtype'' magazine description confirms that their relationship between them can be seen as romantic or based on trust, [[DiscountLesbians give or take a few complications]].]]

* HilariousInHindsight: ''[[VideoGame/{{Fortnite}}]]'' of all things had a giant cube appear out of the sky over a lake in 2018.

* HilariousInHindsight: ''[[VideoGame/Fortnite]]'' of all things had a giant cube appear out of the sky over a lake in 2018.

* CounterpartComparison:
** Almost immediately after his introduction, some fans started comparing [=zaShunina=] to [[Anime/NeonGenesisEvangelion Kaworu]] for their similar designs, origins, and color scheme.
** As the plot goes on, some called the series the Japanese answer to works like ''Film/{{Arrival}}'', ''Literature/ChildhoodsEnd'', and ''Film/TwoThousandOneASpaceOdyssey''.
** [[spoiler:Yukika]] has been compared to [[spoiler:[[Literature/{{Twilight}} Renesmee]]]]. Both are [[spoiler:the supposedly impossible daughter of a wildly unpopular and [[StrangledByTheRedString forced]] OfficialCouple]], who [[spoiler:serve mainly as a DeusExMachina and destroy (metaphorically in Renesmee's case, literally in Yukika's case) the [[FanPreferredCouple much more popular possible love interest]]]].

** For a character with 3 minutes of screen-time ''total'', [[spoiler:Yukika]] is ''hated'' by pretty much the entire fanbase of the show.

** [[spoiler:Yukika]] has been compared to [[spoiler:[[Literature/{{Twilight}} Renesmee]]]]. Both are [[spoiler:the supposedly impossible MarySue daughter of a wildly unpopular and [[StrangledByTheRedString forced]] OfficialCouple]], who [[spoiler:serve mainly as a DeusExMachina and destroy (metaphorically in Renesmee's case, literally in Yukika's case) the [[FanPreferredCouple much more popular possible love interest]]]].

* MarySue: Well, Tsukai is beautiful and dresses well (despite being supposedly a tomboy), has an exotic name and blue hair, is a good negotiator (perhaps only supposedly), and turns out to be an Anisotropic being who's administered the universe for billions of years... with a soft spot for protecting Shindo. Even as an Anisotropic, some might consider this a bit too much of a coincidence simply to give Shindo a powerful love interest.

* AwesomeMusic:

* FunnyMoments:

* HeReallyCanAct: Creator/TakumaTerashima is [[PlayingAgainstType better known for using a cutesy voice]] in fluffy {{Bishonen}} series like ''VisualNovel/UtaNoPrinceSama'' and ''Anime/CuteHighEarthDefenseClubLove'', but his performance as [=zaShunina=] successfully depicts how [[StarfishAliens inhuman]] he is [[HumanityIsInfectious until he isn't]], pulling off CreepyMonotone, [[spoiler:LoveConfession]], [[spoiler:{{Yandere}}]], and finally [[spoiler:TearJerker]] equally well and gradually.

* VisualEffectsOfAwesome: One thing that can be generally agreed on is the exceptional CG art and animation. Lots of praise went around for the expressiveness of the 3D models.

* HoYay: Don't be fooled by the heavy political themes and the overall FirstContact main plot of the series. There is plenty of these moments.
** Hanamori constantly ends up in a SecurityCling to Shindou.
*** When he sees Shindou screaming in pain in response to zaShunina's [[BrownNote failed attempt to communicate with him through telepathy]], [[CowardlyLion Hanamori]] ''almost instantly'' overcomes his fear of the the AlienGeometries that was surrounding them (as well as the traumatic experience that was getting trapped inside of Kado in the first place) and rushed to help him.
*** When he finally exits from KADO in episode 6, Hanamori is running to Shindou while shedding TearsOfJoy and almost jumps on him before barely stopping. Shindou than gives him an AffectionateGestureToTheHead.
** When Kojiro and Asano meet again they end up hugging each other in relief. Now remember Japan's cultural standards regarding hugs...
** The biggest one, however, is whatever is going on between [[BlueAndOrangeMorality zaShunina]] and [[{{Ambadassador}} Shindou]]. Seriously. A human shouldn't feel that comfortable around an alien. [[EveryoneCanSeeIt This was noted even InUniverse.]]
*** The fact that they are essentially turning more and more into HeterosexualLifePartners with each episode really raised quite a few eyebrows, not just among the YaoiFangirls.
*** In the preview for episode 6, zaShunina seems to be giving Shindou a hug from behind.
*** After the episode was released, Yaha-kui doesn't exactly ''hug'' Shindou, but he is still had NoSenseOfPersonalSpace around him.
*** Yaha-kui openly says to Shindou in in episode 6 that he is glad how much Shindou got accommodated to the anisotropic.
*** In episode 12, they [[spoiler:exchange a (one-sided at least) HeadbuttOfLove before their deaths]].
*** Yes, [[https://68.media.tumblr.com/850afd6d780353078d5445f5d5eb30f9/tumblr_oqwhjehVk71qmlmyuo1_1280.jpg this]] is official artwork. ''They look like they're engaged!''
*** A similar official art is [[https://78.media.tumblr.com/109a088ea29dddef05c5be83c0e3c9eb/tumblr_owz5qgXjtg1qizuabo3_540.png recorded]] in a now-archived ImageBoards post.
*** [[https://78.media.tumblr.com/37b1dbbfbb11c49536fff9b492803297/tumblr_inline_owz4v5cttf1qhrlsl_1280.png This]] cut scene is an even more blatant LoveConfession.
** Episode 9 has two instances in the same episode: Hanamori saying that he "likes" Shindo, and [=zaShunina=] revealing that he developed feelings for him, but in a very different and unhealthy way.

** Cemented as such after the ending. Virtually every one of the few fanfics the series has on Website/ArchiveOfOurOwn is this pairing.

** "I AM... THIS PLANET'S BIGGEST FAN!" was ''supposed'' to be a PreAssKickingOneLiner, but did not help the image [[spoiler:Saraka]]'s detractors had of [[spoiler:her as immature with nothing more than a schoolgirl crush.]]

* PeripheryDemographic: The series was aimed at the {{Seinen}} demographic, but also attracted a [[YaoiFangirl fujoshi]] fanbase with its cast of cute and handsome men and their close relationships (not to say that said fans aren't interested in the science fiction as well).

* DesignatedHero: [[spoiler:By the end, Shindo and Saraka are this. While she did have a point about messing with the natural order of the world, it came earlier in the series before her HeelFaceTurn, and they don't really make any sort of case why zaShuina's attempt to forcefully take humanity into the anisotropic is wrong while their decision to stop him and deny any human from being able to go into the anisotropic is right.]]

* {{Narm}}: The name of Yaha-kui zaShuina was meant to invoke a Lovecraftian StarfishLanguage, but sounds more silly than scary.

* RewatchBonus: After Episode 6's reveal that [[spoiler:[=zaShuina=] has been slowly tampering with Shindo's mind]], previous episodes before the revelation become much more interesting to look at. The same goes for Saraka after episode 9.

* NightmareFuel:
** Episode 0 has [[WhamShot the sudden arrival of KADO]] [[DaylightHorror witnessed by the protagonist in the airplane that was just about to go of.]] Things only get worse when [[AlienGeometries KADO]] makes contact with the airplane in Episode 1. [[BodyHorror Poor Hanamori...]]
** Yaha-kui's unintentional MindRape of Shindou.
** The [[TheWarOnTerror rather]] [[LensmanArmsRace obvious]] [[GreatPoliticsMessUp reasons]] why the Wam is posing a very real danger to humanity.
** [[GenreBlind The fact that the UN was more concerned with the Wam]], [[{{Greed}} rather]] [[{{Realpolitik}} than]] [[StarfishAliens the]] [[BlueAndOrangeMorality one]] [[ElephantInTheLivingRoom who brought them in the first place.]]
** Yaha-kui zaShunina already used rather weird devices whose obvious potential to be abused with disastrous consequences have been regularly acknowledged, but [[spoiler: the Sansa]] is in a tier of its own. While not necessarily as directly dangerous as the Wam, [[UncannyValley it is terrifying in every way that the Wam isn't.]] [[BrainInAJar For starters, it looks like a human brain.]] [[MindScrew When it activates,]] [[spoiler: [[MindScrew the Sansa]]]] [[MindScrew essentially divides itself in ''loafs'' and starts assuming movements that make it look like either a bacteria/ameba and in doing so it gradually starts resembling a worm.]] ''Then'', it causes [[TheFourthWallWillNotProtectYou those who view it (even on TELEVISION)]] to see multiple versions of themselves while their surrounding looks like a DisneyAcidSequence [[UpToEleven on crack.]] In [[IntrepidReporter Genno's]] case, one of his duplicates at first looks just as confused as Genno - almost like a mirror image - but then suddenly delivers a rather unnerving PsychoticSmirk.
** Things also get pretty disturbing when [[spoiler: estimated ''billions'' of people]] have a reaction to watching [[spoiler: the Sansa]] on television in Episode 8, which almost looks like '''a mass epilepsy attack!'''
** Yaha-kui zaShunina himself delivers a quite chilling borderline-SlasherSmile at the end of episode 8.
** While Yaha-kui knocks down all of the clone Shindos, upon closer inspection one can see that some of them were put down in very uncomfortable positions. Some have their legs backwards or bent at certain angles, and some are twisted entirely.
** Kanata having to watch a clone Shindo be demolished in the Kado, complete with bone crunching sounds. It's not the real thing, but she's still clearly disturbed by the sight.

* TheWoobie: By the end of the series, most people felt very bad for Hanamori. He's a generally innocent guy who, while clumsy, tries his hardest. He ends up manipulated by his best friend, is crying his eyes out when he's told to complete what may be his last request, and the ninth episode reveals that he's in love with Shindo, making all of his reactions towards him worse. [[spoiler:Then we learn in the last episode that he raised Shindo and Saraka's child for 16 years, she calls him by his first name despite this, never treats him like a father figure and leaves him after her purpose is served, and that his friend essentially dies.]] Someone just give the poor man a break and a hug.

* CreatorsPet: Despite interviews stating otherwise (which may or may not make it better), some disgruntled views find this to be the case for Saraka. All of her development as a character is seen as rushed, her viewpoint and opposition isn't explored very well even if it does make sense to later revelations, her reveal as [[spoiler:an ansiotropic being]] is rushed as well, but the audience is expected to take her side and she gets much of what she wanted out of the whole ordeal.

* StrawmanHasAPoint: Tsukai has every reason to be suspect of [=ZaShunina=] despite his gifts to humanity, such as his unwillingness to tell humankind his real plans and this sudden burst of human evolution where it previously was a slow process. But she's not able to make a clear argument for why, and her actions seem to represent the halt of progress going by the symbolism in the opening.

* BaseBreakingCharacter: Saraka has been attracting some negative attention, due to her seeming immaturity as a negotiator compared to her peers, her {{Tsundere}} traits, and her opposition to [=ZaShunina=]. By the halfway point in the series, she acquired a large group of detractors, but after [[spoiler:her reveal as an anisotropic being like [=ZaShunina=]]], some viewers justified her stance and found her a more interesting character. The romance she eventually finds herself in with Shindo and how it was written is also a point of contraction with detractors.
* Shindo comes off as this in the last third of the show, given that he's willing to do some underhanded manipulations of even his closest allies in order to move forward. His moral ambiguity is even called into question by some fans.

* UnintentionallyUnsympathetic: Shindo comes off as this in the last third of the show, guven that he's willing to do some underhanded manipulations of even his closest allies in order to move forward.

* JumpingTheShark: Consensus seems to be that once episode 10 comes around, the shows quality takes a nosedive.

* CreatorsPet: Despite interviews stating otherwise (which may or may not make it better), some disgruntled views find this to be the case for Saraka.
