History YMMV / HaiyoreNyarkoSan

** Cuune.
* TheyWastedAPerfectlyGoodPlot: Not exactly ''plot'', but more than a few fans feel that the Lovecraft references should have been better utilized. Some have even accused them of being window dressing to make the series less generic.

* SeriousBusiness[=/=]RuinedForever: Go to any message board where people discuss this show, and you'll probably find at least one hardcore Cthulhu fan who's screaming about how Lovecraft is spinning in his grave over his "great works" being turned into a generic piece of "moeshit". Even if the story contains a lot of subtle {{Mythology Gag}}s referring back to the Mythos, and author Manta Aisora has confirmed that he puts a lot of work into getting as many details from Lovecraft's work into the story.

* UnfortunateImplications: Of the StealthPun variety. Cuuko is a being of living fire with PsychoLesbian tendencies. Consider one of the derogatory names used to describe homosexuals.
** Some have claimed this about Cuuko herself.

* {{Moe}}: Hasuta
** Arguably, Nyarko and Cuuko also count, given [[EldritchAbomination who they really are]]

Also qualifies as ComplainingAboutShowsYouDontWatch, since the story contains a lot of subtle {{Mythology Gag}}s referring back to the Mythos, and author Manta Aisora has confirmed that he puts a lot of work into getting as many details from Lovecraft's work into the story.

* CrowningMomentOfFunny: The eyecatch for episode 2 - Nyarko drinking "Cola of Cthulhu".

* InformedAttribute: We're told that Nyarko is very intelligent (always did well in school, graduated a top-level college) and a well-respected space cop. We never see her exercising anything beyond normal intelligence, and some of her interaction with her superiors suggests she's on thin ice. These both might be justified by her attitude; she acts like she's on vacation because she ''is''[[note]]In the novels, after busting up Nodens's smuggling ring she takes 300 years of paid leave to be with Mahiro[[/note]], and she addresses her boss in the same flippant, casual way she addresses everyone.

** The opening for the [[http://www.youtube.com/watch?v=hglA3kHKaX0 second season]], W, also has a catchy tune as well.

** The [[http://www.youtube.com/watch?v=Lt6b6x6XAcQ first ending]] for W has a nice beat as well.
** Another ending song for the second season, this time focusing on [[http://www.youtube.com/watch?v=DoxjPYvXVKM Tamao Kurei]].
** Another ending song for season 2, this time with emphasis on [[http://www.youtube.com/watch?v=E3cB4O5P9SQ Kuuko.]]

* EarWorm: Days after the trailer was out, people thought the [[http://www.youtube.com/watch?v=YAaUNyDOjnw beginning part of the song was catchy.]]

** And what's hentai infamous for? Of course it would appeal to them!

*** The cute chant heard throughout that song, "SAN-chi, pinchi!", which means "You SAN points are in trouble!" This was actually voted the 4th most memorable anime CatchPhras of 2013.

* InformedAttribute: We're told that Nyarko is very intelligent (always did well in school, graduated a top-level college) and a well-respected space cop; but most of the time we just see her goofing off, trying to get into Mahiro's pants, and generally acting like she's on vacation. Justified in the light novels, where she actually ''did'' take a paid vacation after arresting Nodens; as for protecting the Dreamlands, that doesn't seem to require much effort since Nyar-O killed all the Great Ones.

* ValuesDissonance: This is a ''Japanese'' series based in characters written by [[HPLovecraft someone who was infamous for being a notorious racist]] and they're mostly used for [[RuleOfCool coolness]] and [[PlayedForLaughs laughs]], possibly ''[[MisaimedFandom without knowing the cultural background of those stories]]''.

* InformedAttribute: We're told that Nyarko is very intelligent (always did well in school, graduated a top-level college) and a well-respected space cop; but most of the time we just see her goofing off and trying to get into Mahiro's pants. Potentially justified, since she ''did'' take (300 years' worth of) paid vacation after arresting Nodens, and protecting the Dreamlands doesn't require a lot of effort, especially after Nyar-O killed all the gods there.

* InformedAttribute: We're told that Nyarko is very intelligent (always did well in school, graduated a top-level college) and a well-respected space cop; but most of the time we just see her goofing off and trying to get into Mahiro's pants. It might be because she acts like she's on paid vacation rather than doing her job (and thus only shows her real strengths in LetsGetDangerous moments), or perhaps [[TheUnfavorite Nyar-O]] was exaggerating due to his hatred of Nyarko.

* BadassDecay: Nyaro takes this to the logical extreme. At the beginning of the episode, he is introduced after having slain several gods, with bad lighting that barely reveals his features and apparently reveling in the carnage. By the end of the episode, he's been chased by the police, defeated several times ''by accident'', and his OneWingedAngel form [[ATwinkleInTheSky blasts off]] after basically having his toe stubbed. His defeat in the light novels is different, but no less demeaning (and still results in him blasting off).

* GeniusBonus: In one episode, Nyarko uses Series/KamenRiderOOO's transformation pose to change into her Full Force Form. The sharp-eyed viewer (and one familiar with that series) will notice that the energy rings that appear correspond to OOO's Kuwagata (Stag Beetle), Tora (Tiger), and Condor Medals. Applying the naming convention used for OOO's forms, one gets Ku-To-Ru - the Japanese pronunciation for "Cthulhu".

* FridgeHorror: In the DatingSim episode, Mahiro is unwillingly jumped around between the key events of the game, skipping over large portions of the school year. We're outright never told how the others experience it, but the fact that Nyarko had the time to knit a (rather long) scarf for Mahiro's Christmas present implies they lived out the whole thing. That in and of itself is pretty scary, but then one has to wonder what happened to Mahiro in the meantime -- did he simply disappear, or was he on "autopilot" like Adam Sandler's character in ''{{Film/Click}}'' when he fast-forwarded time?
