History YMMV / AllOfUsAreDead

** Also with ''Manga/SchoolLive'' (or more accurately, the first arc of that series to be exact), due to having the same premise, albeit DarkerAndEdgier as well as more actionized.

* MememticMutation:

* SugarWiki/SheReallyCanAct: Lee Yoo-mi was absolutely praised by the viewers for her capability to make them cry for such a tragic character as [[Series/SquidGame Ji-yeong]], yet make them LoveToHate her as [[AlphaBitch Lee Na-yeon]], being a proof of her versatility as an actress.

** A common criticism about the series is that it establishes a large number of characters to the main cast, but most end up unfocused and with no development on their personalities and backstories. While most of the cast members manage to have ADayInTheLimelight, sadly it still feels too little because it's right before the episodes of their deaths and there are even other surviving characters like [[ButtMonkey Dae-su]] and [[TheLoad Hyo-Ryung]] ending without even receiving focus and leaving them as [[FlatCharacter Flat Characters]].

* CryfortheDevil:

* VillainHasAPoint: Lee Byeong-chan makes an excellent point to Detective Song Jae-ik when he says, "They were all complict." If anyone, at any time, had made an effort to really stop Gwi-Nam instead of shrugging it off as "the victim's problem", Byeong-chan would not have made a virus that very much became "the victims' problem". (YMMV on how much of a villain Byeong-chan actually was.)

** While he created the Jonas Virus and thus caused much of the deaths in the series, it's quite easy for viewers (especially those with children too) to understand why Professor Lee Byeong-Chan created the virus in the first place. His son was an innocent boy who was mercilessly harassed by bullies even when he tried to change it schools several times. In the flashbacks in which it was shown that he tried to ask different authorities for help, they just ignored his pleas and they allowed their son to continue to be hurt to such an extent that one day Jin-su tells his father that he wants to end his life. After Jin-su had attempted suicide to end his pain, Byeong-chan was so broken that he created the virus in desperation so that Jin-su could defend himself from people who hurt him.

* CryfortheDevil: Despite her horrible behavior earlier in the series, it's hard not to feel bad when Na-Yeong meets a bloody death at the hands of Gwi-nam. After Na-Yeong not only begins to feel remorse for causing Gyeong-Su's death but also remembers the sacrifice her teacher made to save her and tries to bring food to the other surviving students to apologize and fulfill her teacher's last wishes.

* TheScrappy: Or rather DamselScrappy. Despite being one of the main characters, Seo Hyo-Ryung is one of the characters that annoys or irritates viewers the most. Not only is she one of the students who least helps or acts in fights, but she is constantly a DamselInDistress who has to be saved or serving as TheLoad when her friends try to flee from zombies. At the beginning of the series when there were times when her teammates were in danger or sad, instead of constantly helping she stays quiet or gets scared and lets others take over. The fact that she survives to the end of the series unlike other much more interesting students like Gyeong-su, Ji-Min, and even Na-Yeon doesn't help either.

** While it is later revealed that he survives at the end, seeing Gwi-nam being surrounded by zombies and eaten alive in the library as he screams in pain and begs Cheong-San for his life is incredibly satisfying after remembering the bullying he caused him to Eun-ji and that he had previously tried to kill Cheong-San in that same library.

** Lee Na-Yeon intentionally infected Han Gyeong-su just so she won't say sorry to the group for being wrong. Seeing her get a bloody death at the hands of [[spoiler: Gwi-nam]] feels rewarding.
** Before that, Nam-Ra finally slapping Na-Yeon, which she so well deserved by that point.

* CatharsisFactor: Lee Na-Yeon intentionally infected Han Gyeong-su just so she won't say sorry to the group for being wrong. Seeing her get swarmed by the zombies themselves feels rewarding.

* TheyWastedAPerfectlyGoodCharacter: Gyeong-su was not only a NiceGuy, Cheong-san's best friend and one of the few characters who dared to fight against zombies when the apocalypse began, but he also had an incredibly realistic and identifiable background that with enough development could make him a character on the level of Su-hyeok or Nam-ra. However in the end he is used as a SacrificialLion in the same way as On-Jo's best friend (I-Sak) for the development of Cheong-san and leaving him as a waste.

* LoveToHate: Yoon Gwi-Nam is a despicable bastard whose cruel actions as the school bully initially starts the zombie apocalypse in the first place and is willing to kill others to accomplish his petty goal but his actor, Lee Yoo-Mi's performance is spectacular when portrayed with a charming attitude which not only made the actor's popularity skyrocketed but also made us enjoy hating the villain's guts!

* SugarWiki/HeReallyCanAct: Lee Yoo-mi was absolutely praised by the viewers for her capability to make them cry for such a tragic character as [[Series/SquidGame Ji-yeong]], yet make them LoveToHate her as [[AlphaBitch Lee Na-yeon]], being a proof of her versatility as an actress.

* FriendlyFandoms: Unsurprisingly, there's an obvious overlap between ''All Of Us Are Dead'' fans and ''Film/TrainToBusan'' fans. It definitely helped that the show [[ShoutOut name dropped]] the movie when the students realized that they are dealing with a ZombieApocalypse.

* SpiritualAdaptation: The show is basically ''Manga/HighschoolOfTheDead'' the live action, sans the excessive FanService of the anime. Both shows had at the core {{Second Year Protagonist}}s escaping a highschool full of zombies, the handsome guy who has ShipTease with an upbeat tomboy and an AloofDarkHairedGirl, the fat friend being the PluckyComicRelief, a RichBitch with pink motifs and green uniforms.

** Park Sun Hwa has also gained sweetie despite her short time due to being a reasonable authority figure and being one of the few adults who genuinely wants to help and protect the students during the Apocalypse.

* LoveToHate: {{Jerkass Yoon Gwi-Nam}} is a despicable bastard whose cruel actions as the school bully initially starts the zombie apocalypse in the first place and is willing to kill others to accomplish his petty goal but his actor, Lee Yoo-Mi's performance is spectacular when portraying with a charming attitude which not only made the actor's popularity skyrocketed but also made us enjoy hating the villain's guts!
