History YMMV / MagnusChaseAndTheGodsOfAsgard

** While not as drastic as many examples of this trope, Magnus's behaviour within the first couple chapters has drawn some contention.

* UnintentionallyUnsympathetic: Early in the first book, Magnus justifies his stealing from people better-off than him, by arguing that they're rich and wealthy and so they can afford to give up a few of their nice things for his well-being. He then proceeds to go live in what amounts to the world's greatest five-star hotel where his every whim is catered to at no cost to himself. His entry into the Hotel Valhalla is supposedly justified due to how he died a hero's death, but the people he saved on the bridge were only in danger because Magnus himself was there, and the fact that he did actually die was almost completely inconsequential to the rest of the story. Some feel that the book is implying that the homeless are entitled to and should all be given high-class accommodations, even at the expense of others, just for the fact that they're homeless (that being said, Magnus isn't necessarily presented as being in the right when he mentions stealing from others).
** Some also feel that Magnus is only homeless by choice, as he has living relatives that he could stay with but deliberately chooses not to go to them for help. Others feel that he really didn't have a choice, since his mother had explicitly warned him to stay away from Randolph, and while Annabeth and her parents probably would've been happy to take him in, Magnus hadn't had any contact with them in years, didn't know where they lived, and as it happens, they were hundreds of miles away; it would have been immensely difficult for him to contact them.

*** On one hand, his sudden tangent on how common homelessness on transgender people (like Alex) followed by his distaste for Valhalla's luau for being "cultural-appropration"-ey seems to come out of nowhere. Some feel this is a bit of an AuthorTract and that, while [[DontShootTheMessage Magnus is totally right about how often transgender teenagers are often homeless, his tone makes him seem almost condescending]]. On the other hand, some feel that the message about homeless transgender teenagers absolutely needs to be said, or that his sudden mention of Cultural Appropriation was a secret TakeThat.

** The implication (even if it isn't true) that the Norse gods might be creations of Allah didn't sit right with some fans. Outside of the fact that Norse worshipers do still exist and it is extremely disrespectful to them, to say the least, the Percy Jackson series had always taken a hands off approach to the actual religious nature of the Gods, and stuck to the fun fantasy aspect. The fact that the Gods themselves gave some support to the idea just makes things worse.

* HarsherInHindsight: Not only is Thor explicitly contrasted with his Franchise/MarvelCinematicUniverse counterpart when first introduced, but he's depicted as slovenly, unhygienic, and kind of a couch potato (albeit both badass and goodhearted). Come ''Film/AvengersEndgame'' however, [[spoiler: that version of Thor has ''also'' become a slovenly, fat, unhygienic gaming couch potato...out of depression for failing to stop Thanos]].

** The way that the Norse
gods are portrayed has caused contention due to being played more for comedy. While some like this and appreciate that they stand out from the JerkassGods of previous works, others wish that they would be taken a bit more seriously.

** samirah's arranged marriage is also a source of contention. Some like the representation while others see it as gross and even grooming

* NeverLiveItDown: Despite Alex Fierro's development in the third book, most detractors are more likely to remember them as being a mean anvilicous jerk in the second book who threatened everyone who referred to them by the wrong pronoun. Even among their supporters there are those who believe that their actions were extreme and harsh.

* AuthorsSavingThrow:
** Readers were surprised by Magnus' mild cursing in the first book, which many felt was uncharacteristic for Riordan. Come book two, not a single "dammit" appears, though the Hel/hell joke is kept due to RuleOfFunny.
** TJ, Gunderson, and Mallory were practically billed as main characters, yet they were offscreen for most of the first two books when Sam, Blitzen, and Hearthstone took the role of main supporting characters. The third book has them joining the main four, along with Alex, sharing backstories, and fighting alongside him.
** Alex doesn't go as {{Anvilicious}} with his/her gender fluidity in the third book.

What makes it worse is that Magnus is only homeless ''by choice'', as he has living relatives that he could stay with but deliberately chooses not to go to them for help.

* CompleteMonster: from ''The Sword of Summer'':

** . The way that the Norse gods are portrayed has caused contention due to them being portrayed as too much comedic relief. While some enjoy this others would've preferred them to be a bit more serious
