* AlternateCharacterInterpretation:
** By the end of the HalloweenEpisode, is Lloyd genuinely happy he gets to take Francine trick-or-treating after he spent what he thought was decades lamenting he'd never see his family again? Or was he trying to keep Francine happy out of fear of whatever else she might do to him after the MindRape she pulled on him and the others?
** In "Neither Boy Nor Girl", was Zoit saying that the other kids will have to wait until they develop a crush on someone to find out the gender they chose to identify as meant to be heteronormative or Zoit's way to waiting until they figured out their full identity (orientation included) before revealing their gender?
** Is Lloyd asking if he's grounded in 'Nora's Big Date' just him being a child knowing they screwed up and expecting to be scolded for it, or him being a child who was once ''grounded for a month'' on his ''birthday'' for things that arguably weren't even his fault? Nora wouldn't even let him explain himself without threatening to make it ''TWO'' months instead. In the latter case, it's no wonder that he never tried to talk to his mother beforehand about his feelings involving Herb.
* {{Applicability}}: Cindy the two-headed girl - where one head is nice and the other is aggressive - could be considered a parallel to someone with bipolar disorder or other mental illness.
* BaseBreakingCharacter:
** Brittany gets some hate for her AlphaBitch tendencies but the reveal that [[spoiler: she's really a Type A {{Tsundere}} for Lloyd]] is divisive. Some feel it doesn't justify her bullying, while others are more sympathetic to a preteen who doesn't know how to process their feelings.
** Eddie gets some love for being a DeadpanSnarker and getting a lot of good lines. However he's also the bad influence who gets Lloyd into trouble, rarely apologises for his worst moments, and is an overall {{Jerkass}}. The worst of them is when he causes destruction on Douglas's cousin's farm and his first instinct is to make up a good excuse to cover it up rather than trying to fix it.
* FairForItsDay: The episode "Neither Boy Nor Girl" is about an alien kid named Zoit whose species chooses to be a boy or girl when they turn thirteen. It defines gender through stereotypically gendered activities like enjoying sappy movies and belching contests, and the ending implies that boys must develop crushes on girls and vice versa. However, it addresses the concept of androgyny and choosing one's gender years before transgender issues started to get more traction in the media, and Zoit calls their classmates out for trying to influence their choice.
* NightmareFuel:
** Francine telepathically forcing Lloyd and friends in a BadFuture scenario where the station is destroyed and everyone excluding Lloyd becomes a monster, just because he accidentally scared her and didn't take her trick-or-treating in the HalloweenEpisode.
** The episode where Nora dates another man, who is revealed to be wearing a mask. Although he's quickly shown to not be evil, the scene where Lloyd first sees his real face is quite startling.
* OlderThanTheyThink: ''WesternAnimation/TheOwlHouse'' isn't the first Disney cartoon to have a non-binary character. This show had one in the form of Zoit.
* SoOkayItsAverage: It's ''far'' from a terrible show, but it wasn't as memorable or as well-written as ''WesternAnimation/{{Recess}}'', despite being made by the same people.
* TearJerker:
** Lloyd's telling Cindy off at the school dance is very hard to watch. Sure her other head was mean to him, but he had no reason to yell at the nice head too. Afterwards she sits crying, wondering in vain if Lloyd was just joking.
** Nora's date having his identity exposed. Everyone had assumed he was a monster based off how he looked, and he is reduced to tears by the situation.
** The show never dwelt on it but there's something pretty sad about how Lloyd's response to a customer complaint about Eddie's treatment of her pet in "Pet Wars", a fairly justified one, not by saying something like "I'll make sure it doesn't happen again" or throwing Eddie under the bus for being himself (which would have been somewhat mean but an understandable reaction) but by whipping out a HumansAreBastards line, meaning that despite his mother being the openminded ReasonableAuthorityFigure she is, Lloyd has no issue using a racist statement for his benefit. Not to mention it placates the customer, meaning she's apparently fully in the camp of "believe the worst of humans [[HumansAreBastards simply because they're humans]]".
** The basic concept of "One Day", the core four of the series never becoming friends, is already pretty depressing but the fact that Rodney, Lloyd's best friend in the altered timeline, greets Lloyd by implying that the pair of them routinely beat up "dorks" itself implies that alt Eddie possibly isn't just timid by nature; it's possible that he was ''actively afraid'' of Lloyd because in the altered timeline, Lloyd assaulted him at least once.
* TheyWastedAPerfectlyGoodCharacter: Herb, Nora's "monstrous" date, never appears again after his intro episode and in fact, is never even ''mentioned'' again despite the fact that Nora clearly enjoyed his company and obviously was ready to reenter the dating scene.
* TheyWastedAPerfectlyGoodPlot: Despite the webtoons that implied humans are looked down upon by most other races, this only came up once in the actual show: in "Pet Wars", when Lloyd responds to a customer's complaints about how Eddie treats her pet by [[FantasticRacism implying his behavior derives from him being]] [[HumansAreBastards a human]]. Not only does this never come up again within the episode itself (despite Eddie being in earshot, he apparently had no issue with ''one of his best friends'' painting him as violent simply for being human) but the show never addresses Lloyd's apparent willingness to buy into anti-human sentiments when it suits him. It would have been a good lesson to have it pointed out that "if you're making a blanket statement about someone based on anything that isn't them personally, that's prejudiced at best and racist at worst and you need to check your biases".
* UnintentionallyUnsympathetic: Douglas in "That's Debatable" for calling Lloyd the "most selfish boy [he] ever met" because the later didn't help him prepare for the debate. Whilst we are meant to sympathize with Douglas because he is suffering from the pressure of having to study, the problem is that was Douglas' ''own'' idea to do all the work, whilst Lloyd only sits with him because the debate requires a two-person team. The only reason Lloyd even agreed to act as the second person begin with was due to a mix of guilt-tripping and Douglas insisting that the vacation prize would be great. In fact, when Lloyd brings up the deal, Douglas' only response is "it was an idiotic deal" acknowledging how short-sighted the original plan was, [[NeverMyFault yet he still treats Lloyd as being at fault]].
