* AssPull: A common criticism of the series is that many of the solutions and prophecies seem to be [[NewRulesAsThePlotDemands improvised]].
* AwesomeArt: The manga gives it a rather animeseque style that some feels really befits the series, making it seem almost like a CrapSaccharineWorld.
* CompleteMonster: [[DepartmentOfRedundancyDepartment The One Who Is The One]] is the [[ANaziByAnyOtherName brutal dictator of the New Order]], and the [[BigBad ultimate evil in the story]]. Deciding all life was meant to cow before him after being shunned for his affinity of magic, The One established the New Order as his dictatorship, and quickly turned his new kingdom into a hellish realm for all the inhabitants. Proclaiming all forms of art, including magic, to be sinful, The One has any and all practitioners of these, along with their family members, brutally tortured and executed, with most of his victims being [[WouldHurtAChild children]]. Along with personally vaporizing dozens of children at a time to relieve boredom, subjecting hundreds of adults and children to vivisections, and interfering with the afterlife to [[AndIMustScream leave countless spirits wandering in purgatory]], The One spares no expense in quashing any rebellions against him, from bombing entire cities to unleashing terrible plagues onto the public, all of which claim more innocent victims than rebels. [[BadBoss His own minions]] faring no better, The One sadistically executes [[YouHaveFailedMe those who fail him]] [[labelnote: through such means as]] freezing them in place and leaving them to be eaten alive over numerous days by birds, turning them into inanimate objects, and exploding them from the inside. [[/labelnote]], and has no concern for them getting caught in the crossfire of his plans. As the ArchEnemy of the Allgood siblings, The One tortures and murders their friends, [[spoiler:vaporizes their parents]] in front of them, and razes their neighborhood to the ground all solely to torture them. Nearly dying after failing to kill the millions of innocents who refused his rule, The One latches onto his [[AbusiveParents abused son]], Pearce's, soul, [[TheCorrupter corrupting the already wicked teen into a sadistic monster]] that he uses to torment the Allgood siblings further. Assuming full control of Pearce, The One attempts to unleash the undead onto the world to devour all in their path, then rule over whatever is left of humanity as a god. A hypocritical [[note]]as he was willing to use magic himself and owned works of art[[/note]] psychopath who hated everything that he wasn't in full control of, The One is one of the most wicked Young Adult Novel villains to have ever been conceived.
* FunnyMoments:
** When Whit and Wisty are put in a mental hospital, Wisty rationalises it as her being insane. The manga makes it even ''funnier'' by showcasing Wisty with a really ''really'' cuckoolander looking face, while Whit just stares at her like he cannot believe what she is doing.
** When Wisty tries to turn Byron into a pumpkin, she turns him into a lion instead. She says "No! I meant pumpkin!"
** Whit and Wisty are ordered to clean their cell toilet with a toothbrush. The manga shows an absolute ''pristine'' toilet room that the guard still says is filthy.
* SeasonalRot: Some feel that the series should have ''stayed'' as a trilogy and that the fourth and fifth books were nowhere near as good as the first three.
* {{Squick}}: Invoked. The IncurableCoughOfDeath that spreads through the society targeting dissents is designed to cause this when people cough up a black ooze.
