* AudienceAlienatingPremise: The anime's unique rotoscoped look has turned off fans of the original manga.
* TheBusCameBack: [[spoiler: Nakamura in Chapter 52.]]
* CriticalDissonance: The anime has become this after its first episode aired. The consensus among many viewers is that it isn't good due to the controversial art direction, while reviewers generally have been quite positive about the series, including the art direction.
* FanNickname: Aku no Potato, based on the... controversial character designs and animation methods employed by the anime. Another favorite is Rotoscope no Hana
* FreudWasRight: Certainly comes true in later chapters, though Nakamura gives clear indication she believes this.
* InternetBackdraft: The anime adaptation was originally subject to this by the truckload due to its rotoscope animation.
* JerkassWoobie:
** Whatever you may think of him, there's no denying that Kasuga's life has become an utter hellhole thanks to Nakamura and he at least deserves some pity. That is, if it wasn't his own fault to begin with though.
*** Some of his problems definitely were his fault. However, it was clear that he was always very meek, insecure and impressionable, making him ripe for Nakamura's destructive influence.
** The chapters leading up to the [[spoiler:TimeSkip]] made Saeki to be a pretty big one as well, even after she committed [[spoiler: rape and arson]] in an attempt to win Kasuga over.
** Nakamura. It is very clear that she is suffering from some kind of [[AmbiguousDisorder severe unnamed mental illness]] and is unable to cope on her own or prevent herself from dragging Kasuga down with her. Also, she very well might have strong feelings for Kasuga, but is unable to express them due to her illness.
* JustHereForGodzilla: Some readers simply stopped caring about the series after Nakamura [[spoiler: was PutOnABus]].
* JustShootHim: Pretty much what many readers of the manga are stating towards Nakamura and Kasuga.
** Kasuga's reception has gotten quite a bit better after the TimeSkip, especially after he TookALevelInBadass out of the blue. Even people who hated him in the past and/or still hate him admitted that [[spoiler: pouring his heart out to Tokiwa ''in front of her boyfriend'']] was a pretty ballsy move. Other people have said that him [[spoiler: finally having something go his way]] made him a more relatable character.
* LoveItOrHateIt
* MagnificentBitch: Nakamura again.
* MoralEventHorizon: Nakamura crosses this when she [[spoiler: smashes Kasuga's father's kneecap]]. Before that, she had done some terrible, terrible things, but that was the moment where her acts of cruelty became irredeemable.
** [[spoiler: Saeki crosses this when she rapes Kasuga]], although readers [[DoubleStandardRapeFemaleOnMale seem to be more ambivalent toward that act]].
* {{Narm}}: The anime adaptation provoked a fair amount of this reaction in some viewers due to its controversial rotoscoped style and its associated quirks, including very strange or occasionally non-existent facial expressions, actors who really didn't look like teenagers, certain directorial choices that created moments of weird pacing and other factors that made it difficult for them to treat the subject matter too seriously.
* NightmareFuelStationAttendant: Let's be real, Nakamura gives [[MiraiNikki Yuno Gasai]] a run for her money on this trope. You ''will'' shudder whenever she interacts with Kasuga.
* NoYay: Some fans feel this way about the ShipTease between Nakamura and Kasuga, and for damn good reason.
* TheScrappy: It's easy to get really tired of Kasuga playing keep-up with the IdiotBall...
** He gets better in the manga [[spoiler:after the TimeSkip]], though not quite enough for some people to call him a great protagonist. At least until he [[spoiler:crushes the evil flower and [[TookALevelInBadass takes a level in badass]]]].
* TheyChangedItNowItSucks: Very much the most vocal complaint of the anime. Some fans claimed the use of rotoscoping was ugly and ruined their enjoyment. In addition, claims of changing the mood of the show to a quieter tone and redesigning the characters were also detrimental. [[WordOfGod The manga's creator has since vocally supported the changes and states he oversaw many of them]]. [[TakeThatCritics He takes a jab at critics]] at the very end of episode 10, when he asks "Why don't I try rotoscoping you?" He also calls viewers "shit-faces" at the end of episode 12, but immediately apologizes for it in episode 13.
** [[spoiler:The TimeSkip]] has drawn some complaints due to [[spoiler:Nakamura being put on a bus as well as Kasuga starting to have an actual romance that has yet to be destroyed by either her influence or his stupidity.]]
* TearJerker: The last few chapters of volume 3 have been this for all characters -- yes, even Nakamura.
** Saeki's TheReasonYouSuckSpeech toward Kasuga is heartbreaking and oddly [[NauseaFuel nauseating]] when you take into account that [[spoiler:she raped him]] yet has the audacity to invite him to lunch... and ''then'' tell him he's a terrible person.
* TrueArtIsAngsty
* UncannyValley: The animation of the anime uses rotoscope instead of traditional anime-style which places the series pretty close to the bottom.
* WhatAnIdiot: Kasuga ''consistently'' falls into this, perhaps out of a desire for self-destruction. He always seems to do the worst possible thing at any one moment, and it always come back to bite him. To say he can't let go of the IdiotBall is an understatement.
* {{Wangst}}: [[{{Imageboards}} A certain Imageboard]] likes to fight over whether this series is great drama or simply "LinkinPark: The Manga".
* TheWoobie:
** Kasuga's parents. They watched their son grow more and more distant only to discover the horrible acts he had committed. His mother eventually broke down and proclaimed herself to be a total failure as a parent.
** Likewise, Nakamura's dad is arguably is one too. It's clear from his behavior that he's concerned and worried about Nakamura, in spite of her psychopathic behavior.
** Kinoshita. She was probably the character that hated Kasuga (and Nakamura) most, but she would soon have [[ToxicFriendInfluence legitimate reasons]] why not to like him, especially considering what happens to Saeki later in the manga. [[spoiler: Post TimeSkip reveals that she feels immense guilt over what happened to Saeki despite the fact that there was really nothing more she could do.]] [[spoiler: She breaks down crying when Kasuga tells her that Saeki's off living a normal life because she feels that Saeki abandoned her. Judging from how she worded it, Saeki's not the only person to do so.]]
