- Anvilicious: Creativity is good, Adults Are Useless, and it's up to the children to change the world.
- Ass Pull: A common criticism of the series is that many of the solutions and prophecies seem to be improvised.
- Awesome Art: The manga gives it a rather animeseque style that some feels really befits the series, making it seem almost like a Crapsaccharine World.
- Complete Monster: The One Who Is The One, deciding all life was meant to cow before him after being shunned for his affinity of magic, established the New Order, became its brutal dictator, and quickly turned his new kingdom into a hellish realm for all the inhabitants, executing anyone who practices any form of magic or art to kick off his reign; this despite using magic and owning works of art himself. Massacring and vivisecting men, women, and children by the hundreds for both experimentation and fun, The One simultaneously bombs and unleashes plagues onto civilian populations to wipe out any rebels against him. His own minions and son Pearce faring no better, The One sadistically executes those who fail him, has no concern for them getting caught in the crossfire of his plans, and abuses and eventually turns the latter into a vessel for his own soul. As the Arch-Enemy of the Allgood siblings, The One tortures and murders their friends and parents in front of them and torments them throughout the series. When his plan to "purge" the world of those unwilling to worship him fails, The One attempts to unleash the undead souls of his victims onto humanity to wipe it out then rule over the ashes that remain. A psychopath who hated everything that he wasn't in full control of, The One is one of the most wicked young adult fiction villains to have ever been conceived.
- Critical Dissonance: The books have sold at least one million copies, but the critical reception of the book has been negative. El Geek furioso de la literatura, a Spanish reviewer, has called it one of the worst ideas put on paper with a laughable plot.
- Funny Moments:
- 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.
- Harsher in Hindsight: A politician gains a loyal following among many adults despite the terrible things he plans on doing when he's made the leader of the free world. Once he manages that goal, he starts having those that don't fit into his "perfect" world detained by a private police/military force. Much of the resistance against him comes in the form of teenagers and young adults, who are dismissed or outright hated by older people for daring to step out of line. The first book was released in 2009, but it feels eerily prescient of the political climate of the late 2010's.
- Seasonal Rot: 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 Incurable Cough of Death that spreads through the society targeting dissents is designed to cause this when people cough up a black ooze.
