History YMMV / DigimonDataSquad

** Yggdrasil. Some people revile him for his KillAllHumans plan, the fact that most of what he tries to do [[ItsBeenDone has been done before]] by [[Anime/DigimonTamers Zhuqiaomon]], [[Anime/DigimonFrontier Lucemon]], and even Merukimon and [=SaberLeomon=] in this very series, and just being a rather forced FinalBoss, while others appreciate him for being an AntiVillain who, unlike some other versions of Yggdrasil, actually has an understandable reason for hating humanity (namely a human attempting genocide on his subjects completely unprovoked) and is in "us or them" situation that was in no way his fault.

** Masaru/Marcus makes a pun on Thomas/Touma's name when they first meet and calls him "Tonma" (This means something along the line of "Stupid" or "Fool"). Because it's a Japanese pun, it doesn't translate well...however another nice pun works, too. In the English Dub, Marcus/Masaru calls him "Nerdstein", a pun on his ''last'' name. Doesn't have ''exactly'' the same meaning as the Japanese pun... but instead keeps the bit about Masaru making fun of Touma.

* UnintentionallyUnsympathetic: Yggdrasil is meant to [[VillainHasAPoint have a point]] about how HumansAreTheRealMonsters and uses that as justification to destroy the human world to save the Digital World after Kurata destroys the barriers separating them both. However, 99% of the evil humans did against Digimon were entirely on Kurata's initiative, and Yggdrasil [[TheGodsMustBeLazy didn't lift a finger to stop either of his genocidal campaigns]]. When Kurata was defeated by ''humans and digimon working together,'' only then did Yggdrasil get off his ass...[[{{Hypocrite}} to commit genocide against humanity]].

** For that matter, Marcus and Thomas as well. Thomas is either an interesting, sympathetic and endearing character or a stuck-up, unlikable character who nets to get over himself. Marcus is either a total badass whose characterization is unique and original for a main protagonist in ''Digimon'', or a thick-headed JerkAss with unengaging motivations and whose characterization is a stale cliche of HotBlooded fighter heroes we've seen dozens of times before in Shonen anime.

* MagnificentBitch: [[TheDarkChick Nanami]] is a member of the Bio-Hybrid, a trio under the subservience of Akihiro Kurata. [[IntelligenceEqualsIsolation A genius who grew up isolated from everyone because of her prodigious intelligence]], Nanami joined Kurata and hunted Digimon solely as an outlet to escape the droll in her life. Taking an interest in Thomas H. Norstein, Nanami undercuts his plan to protect the waterfall of the Sacred City located on [=ElDradimon=] by easily guessing where he'd be. Spending the entire scuffle against him and Gaomon predicting their every move with utter ease and mysterious grace, Nanami uses their shared experiences and her own dark charms to try and shake Thomas's faith in his friends. While undone by Thomas using a strategy unfathomable to both her and [=MirageGaogamon=], [[VictoriousLoser Nanami gracefully accepts defeat only because she pushed Thomas into using someone else's power]], not his own, and uprooting Thomas's strategy by destroying the coveted waterfall.

* MoralEventHorizon:
** Kurata crossed this at lightning-speed when he returns to the Digital World and engages in a brutal massacre.
** Everyone involved with Kurata's plan, including Hashima, crossed this when they deployed the Gizmon lance. Every last one of them is complicit in the mass murder of an entire city of innocent Digimon.

* ImprovedSecondAttempt: Previous series (with the exception of ''Anime/DigimonTamers''), received some flak for TheHero and TheLancer [[ProtagonistPowerUpPrivileges being the only ones able to reach Mega level]], which made the rest of the team be OvershadowedByAwesome. Not only does ''Data Squad'' have all the main quartet reach Mega Level, all of them also get acces to Burst Mode, which was seen by many as an improvement and one of the better aspects of the season.
