History YMMV / FutureDiary

** Opinions are split on whether Yukiteru is either a major woobie and realistically-written, relatable TragicHero who deserves a happy ending (and a hug), or a spineless, cowardly and whiny angst-bucket on the level of [[Anime/NeonGenesisEvangelion Shinji Ikari]] who is outshined by his more likable supporting cast, while simultaneously also being a DirtyCoward willing to do morally reprehensible things in the name of his goal.

** Known on Pixiv as [[http://bit.ly/s3vQ40 恍惚のヤンデレポーズ]] (lit. "ecstatic {{yandere}} pose") and on [[ImageBooru various *boorus]] as [[http://safebooru.org/index.php?page=post&s=list&tags=yandere_trance yandere trance]].

* EvilIsSexy: Yuno and Minene.

* TooBleakStoppedCaring: In a similar vein to ''Manga/ElfenLied'', the series has drawn a lot of criticism for its constant barrage of dark backstories for VillainOfTheWeek characters that ultimately get killed off at the end of their arcs and the grimdark storytelling exhausting itself after a while to the point where it's just ShockValue.

* TooBleakStoppedCaring: In a similar vein to ''Manga/ElfenLied'', the series has drawn a lot of criticism for its constant barrage of dark backstories for VillainOfTheWeek characters that get killed off at the end of their arcs anyway and the grimdark storytelling exhausting itself after awhile to the point where it's just shock value.
* TooCoolToLive: [[spoiler: Marco, he is the strongest physical combatant, and only dies to [[HonorBeforeReason stay with his lover since he promised he would]].]]

** There are some fans who just can't quite get on board when [[spoiler: Minene Uryu becomes portrayed by the narrative as an AntiHero, which expects them to feel sorry for her tragic backstory and root for her and Nishijima. The reasons stem from her introduction having her gleefully bomb a school room full of innocent children and then take the school hostage under the threat of more bombing and not finding the [[CharacterizationMarchesOn drift away from that characterization]] convincing, to feeling like [[DoesThisRemindYouOfAnything a Middle East-bred terrorist who kills out of hate and intolerance for religion]] is ''way'' too [[RealitySubtext close to reality for comfort.]] Then there's the matter of her acting as if Yuno is [[EvilerThanThou eviler than her]], since while both her and Yuno are horrible, murderous people, Yuno's the only one between them who would likely get a verdict of "not guilty by reason of insanity" in a court of law, whereas Minene accumulated a higher body count in a (generally speaking) right state of mind.]]
** Kurou Amano probably is the worst offender of this trope in the series, as after [[spoiler: making a deal with Yuki's enemies to destroy his diary, stealing a parachute and leaving his son to die, and ''stabbing his ex-wife, Yuki's mother, to death'' in order to stop her from alerting the police, the story suddenly has him break down in remorse over it all, with him being EasilyForgiven by Yukiteru. The fandom, on the other hand, was not so forgiving.]]

** Minene Uryu. "Cosplay Bomber" is not her FandomNickname for no reason.

* GrowingTheBeard: Many think that the anime becomes more interesting [[spoiler: after Fourth's death, with Yuno taking on a more antagonistic role]].

** Downplayed example but quite a few fans actually agreed with Kousaka’s TheReasonYouSuckSpeech to Yukki [[spoiler: right before his death]]
* RootingForTheEmpire: Plenty of fans were rooting for some of the other Diary Holders (like Minene or Yuno) to win instead of Yuki, seeing as how they came off as more sympathetic and likable.
* TheScrappy: Yuki's three "friends", for being irrelevant following the storyline that involves them but still showing up, for being non-Diary holders trying to impact the game, and for generally being TooDumbToLive. It doesn't help that half the time they claim to be on Yuki's side, they're actively plotting against him. Unlike Akise, their leader, who is later revealed to have a very good reason for finding out about the Diary game, they are never given any such reason. Special mention goes to Ouji Kosaka, who has an unpleasant and unlikable personality in addition to his stupidity.

* SpiritualLicensee: For the amount of borderline-NC-17-leveled {{Gorn}} and intense violence and each arc being some sort of DieHardOnAnX premise, it can be seen as though this anime and manga was made by action genre filmmaker Creator/RennyHarlin of ''Film/DieHard2'' and ''Film/{{Cliffhanger}}''. Someone on YouTube [[https://www.youtube.com/watch?v=vzmWU0do-0U even made a fan trailer inspired by the trailer to the latter]].

** The English dub voices of Yukiteru and Yuno. Some fans think their English voices are terrible and don't fit their characters, other fans think that not only does the English voices perfectly fit their characters but also makes it a refreshing change of pace from the high-pitched girly voice and shy, insecure, young boy voice that have been overused a lot in anime.
** ''Future Diary: Redial''; the continuation of the main series has two versions, manga and OVA. Some people prefer the manga version while the others like the OVA version better. While both version lead to the same ending, there are significant differences between the two, such as the addition of BeachEpisode in the OVA. Also, the way [[spoiler:3rd-world Akise]] confronting [[spoiler:3rd-world Yuno]] is totally different in the OVA compared to the original manga version.
* CompleteMonster: Funatsu, though a [[SmallRoleBigImpact minor villain]], caused one of the most horrific events of the series. Once a member of a peaceful cult based around a young girl, Tsubaki Kasugano, who allegedly had prophetic powers. Funatsu killed her parents when they planned to disband the cult, fearing losing his power. Becoming the de facto head of his reformed cult, Funatsu allowed the members to [[RapeAsBackstory rape Tsubaki regularly]], possibly taking part himself, and drugged her to keep her defenseless against their constant assault. So intense was Funatsu's cruelty to Tsubaki that she went insane and began [[WoobieDestroyerOfWorlds plotting to destroy the world]].

* DieForOurShip: Both Yuno and Akise are victims of this, though the latter has it more prominently [[RonTheDeathEater within the fandom]]. Notably, it actually is in-character for Yuno[[note]]the main one from the first world, anyway - her second and third world counterparts, not so much[[/note]] to kill people that come between her and Yukiteru, though it's more often this trope than MurderTheHypotenuse.

* FoeYayShipping: Yuno/Akise (DESPITE their mutual hatred) is a popular alternative ship for Yuno fans who dislike Yukki. Zig-zagged after the release of ''Redial'' manga, as Yuno [[spoiler:from the third world]] has no animosity toward Akise.

* [[https://www.youtube.com/watch?v=m8Nez3BFzp4 "Upper Class Speed Game"]] is an especially epic track that accompanies some major climactic battle scenes.

** Many can agree that [[https://www.youtube.com/watch?v=ZZvJY7_gyfw the first opening song, Kuusou Mesorogiwi by Yousei Teikoku]], is very catchy. It's even more amazing when there are two lyrics that contain nothing but Greek gods' names, while the song overall has three languages sung by the same person: English, Japanese and German.

** While every Diary holder has a catchy ImageSong, special mention must be made for [[https://www.youtube.com/watch?v=98rPvXWHQJk "Justice Rangers GO 12th!!"]]. Which suiting a CrazyIsCool character like 12th, is a bombastic, awesome number straight out of a bad Sentai show.

* TheWoobie: Yuki could be considered this. At the start he is a shy and introverted young boy, and then he gets shoved into a [[ThereCanBeOnlyOne duel to the death]] with a bunch of psychopaths. His only consistant ally is the craziest of them all, the ''biggest'' StalkerWithACrush {{Yandere}} ''ever'', who, at one point, [[spoiler: chains him up and imprisons him, so that no one would get in the way of their love]]. Poor guy.

* TheWoobie: [[spoiler:Second World Yuno]]. Yes, her [[spoiler:stalking Yukiteru]] is kind of reprehensible, but it's never taken to the extremes that [[spoiler:her First World counterpart]] goes to. Her FreudianExcuse is explored in detail more than [[spoiler:the previous Yuno]], and unlike [[spoiler:the next Yuno]], she doesn't live long enough to see a happy ending, getting killed by [[spoiler:her previous incarnation]] without knowing why.

** Opinions are split on whether Yukiteru is either a major woobie and realistically-written, relatable TragicHero who deserves a happy ending (and a hug), or a depressive, cowardly and whiny angst-bucket on the level of [[Anime/NeonGenesisEvangelion Shinji Ikari]] who is outshined by his more likable supporting cast, while simultaneously also being a DirtyCoward willing to do morally reprehensible things in the name of his goal.

* BaseBreakingCharacter: You may think Yuno is a delightful {{Yandere}} as well as the [[JustHereForGodzilla main highlight of the series]], or just an unlikable lunatic [[HypeAversion who hardly deserves the praise she gets]]. Some fans acknowledge that as a person, Yuno is terrible, but as a {{Yandere}} and VillainProtagonist, she's delightful and exciting to watch.
