History YMMV / MiloMurphysLaw

* WhatDoYouMeanItWasntMadeOnDrugs: In general, but moments like the song from "The Llama Incident" are especially trippy.

* HilariousInHindsight:
** Milo's comment about "always wear body armor" is funnier in context if you know about Weird Al's unfortunate misunderstanding with Coolio, which, when resolved, prompted Al to say "I doubt I'll be invited to Coolio's birthday party, but at least I don't have to wear a bulletproof vest to the mall anymore."
** On the poster for the show, there's a satellite coming down from the atmosphere amongst all the chaos. Episode 1 of a [[WesternAnimation/PhineasAndFerb certain show]] featured the kids knocking a satellite out of orbit and spiraling towards Earth. "What goes around comes around" indeed...
** Past ancestors of the Murphy Family evidently vacationed at Mt. Vesuvius, particularly funny when you consider that this show has an {{Expy}} of ''Series/DoctorWho'', where both Creator/DavidTennant and Creator/PeterCapaldi did an episode centered around that volcano and its infamous eruption.
** Balathazar Cavendish tries to get Milo disinterested in wanting pistachios by offering him a gummy bear, considering he’s the real life Doctor Zone, expy of The Doctor, he pretty much offered Milo a jelly baby.

** Bradley. He is a GrumpyBear, but it ensues from Milo always causing chaos near him and stealing the spotlight. He's also honorable about bets and wagering items, like Vitamin C tablets, that Milo would value. In addition, he can't understand why Melissa would rather hang out with Milo than with him, and his one-sided crush is limited to him inviting Melissa to sit next to him.

** Bradley Nicholson was an EnsembleDarkhorse from day one, but after a memorable role in the first handful of episodes as resident GrumpyBear to whom Milo was a SitcomArchNemesis, his role over the first two seasons was largely relegated to walk-on appearances and one-off gags. [[spoiler:Even after his arm was permanently turned into a plant!]]

* UncannyValley:
** Odd for a show where all the characters have large eyes, Sara's seem a little ''too'' big.
** One of Melissa's eyes goes ''halfway'' off her face when she's in 3/4 view.
** Really, if you're coming to this show fresh off from ''Phineas and Ferb'', where nobody in the show had pupils outside of special circumstances, you're going to find characters with pupils 24/7 slightly unnerving. Even more so when they interact with the characters with the more common "[=PnF=]"-styled eyes.

* FunnyAneurysmMoment: Dakota takes offense when Cavendish asks Savannah and Brick why he doesn't have a hot fellow agent. [[spoiler:It's revealed that Dakota keeps going back in time to save Cavendish because they are partners, even if it means Dakota's alternate selves exile themselves to an island.]]

-->'''Dakota: '''Yes, the ZOO! We get to see real, live animals!
-->'''Cavendish:''' ''[[DeadpanSnarker Dreadfully]]'' [[SarcasmMode happy for you]].
-->'''Dakota:''' Happy for ''us!''
-->''Later''
-->'''Future!Cavendish:'''"I'm Going to the Zoo"? Huh, ''we'' went to the zoo, we!

* WhatDoYouMeanItsForKids: Many people were surprised that moments from "The Island of the Lost Dakotas" could be aired on Disney XD, such as the montage of Cavendish deaths, thinking the whole concept was a bit too twisted for the channel.
* WhatDoYouMeanItWasntMadeOnDrugs: In general, but moments like the song from 'The Llama Incident' are especially trippy.

* DieForOurShip: Some fans that were banking on Milo/Melissa really began disliking Amanda Lopez when it turns out the show began developing Milo/Amanda instead. Unsurprisingly, the same happened to Zack Underwood when Zack/Melissa became apparent. Some of the Milo/Melissa shippers decided to [[PairTheSpares ship Zack and Amanda]] purely to get them out of Milo and Melissa's way.

** Despite the show going for Milo/Amanda and Zack/Melissa, there's some fans that prefer Milo to be with Melissa instead, who have yet to show romantic feelings for each other.

* FranchiseOriginalSin: This show has some noticeable flaws that its [[WesternAnimation/PhineasAndFerb parent series]] had:

** It's not uncommon for fanworks to give Dakota [[MismatchedEyes heterochromia]] (usually with one eye brown and the other blue). [[spoiler: The fact that this one was {{Jossed}} in "Island of Lost Dakotas" hasn't done much to change anyone's mind.]]

* TheScrappy: Recurring Raccoon, who only exists to steal people's items due to Murphy's Law.

** The decision to integrate the show more closely with ''WesternAnimation/PhineasAndFerb'' in its second season. Some feel going beyond references to have the previous show's characters regularly appear overshadows the elements that make ''Milo'' stand on its own, leaving it in its predecessor's shadow and making the show's cast occasionally feel like secondary characters in their own series. Others are just happy to see the ''[=PnF=]'' characters live on at all.

** Despite the show seemingly going for Milo/Amanda, there's some fans that prefer Milo to be with Melissa instead, who have yet to show romantic feelings for each other.

* BigLippedAlligatorMoment: In "Fungus Among Us," Dakota reacts happily when told the group is going to the 1960s --what follows is a cutaway gag about four seconds long of Dakota grinning and dancing in just green underwear and faux-hippy tattoos on his limbs and chest. (For those not in the know, it was a reference to ''Series/LaughIn''.) When we cut back to the living room, the kids have reeled back from Dakota in shock and Cavendish asks what the heck just happened. [[LampshadeHanging Dakota promptly tells everyone to just forget it]], and the moment is never mentioned again.

* EarWorm: Considering the theme song is written by Jeff Marsh and Dan Povenmire, and sung by Music/WeirdAlYankovic, it's little surprise.
** ''Go Milo! Go Milo! Go!''
** ''Chop chop chop, chop away at my heart...''
** ''We're going to the zoo! We're going to the zoo! And then we're gonna see some ANIMALS!'' Doesn't help that Vinnie sings it numerous times.[[note]]It's even a hit single, in universe.[[/note]]
** ''[[MostDefinitelyNotAVillain Windoooowless vaaaaan!]]''
** ''It's just a lot of pressure.....''

* ToughActToFollow: To the creators' previous series, ''Phineas and Ferb'', which served as Creator/{{Disney}}'s most popular animated series during its run, and even years after its conclusion, [[AdoredByTheNetwork is still pushed as a flagship series]]. In contrast, ''Milo Murphy's Law'' is seen as disappointing to some fans of that series ([[https://mobile.twitter.com/LalaStellune/status/1075541684065193984 this tweet thread]] sums it up well), to say nothing of the treatment the network gave it during its second season.

** Dakota and Cavendish'a whole subplot in A Christmas Peril. The two have one fight that makes them end their partnership, both still think about it and regret what happened 20 years later, and decide to go back in time to stop that argument from starting, continuously failing but not giving up because their lives just aren't the same without each other.

* TheNotLoveInterest: Melissa Chase is one of the three main characters and has been Milo's best friend for nearly half their lives, having gone on various adventures with him before they met Zack. She often supports and defends Milo against detractors and both are deeply concerned about each other's well-being. Despite this, Milo's romantic interest is actually [[ThePerfectionist Amanda Lopez]], who begins to return his affections in the second season. For her part, Melissa has frequent ShipTease with Zack, with even the characters themselves occasionally joking about their apparent chemistry.

** The liberties and looseness taken with continuity and other story elements. In comparison to ''Phineas And Ferb'', which had a mostly episodic structure for most of its run, only developing story arcs near the end of its third season, ''MML'' utilized an overarching story structure from the beginning. As a result, any discrepancies, contradictions, and {{Retcon}}s, especially those that come from ''Milo'' [[SharedUniverse sharing a universe]] with ''Phineas'' (for example, Dr. Doofenshmirtz being credited for creating time travel when several other characters on ''[=PnF=]'' had done it prior), are given much less leeway here by fans of both series.

*** Doofenshmirtz's as a character in ''MML'' Season 2 either have fans proud that he is finally getting his moment after constantly failing his projects and getting thwarted all the time, or disappointed because they feel forced and ignore his all character growth from throughout ''WesternAnimation/PhineasAndFerb''. This is especially apparent in "Doof's Day Out", where Doofenshmirtz found a family in the Murphys. Some were happy that he found a family after getting abused by his parents in childhood, while others argued that he had already found family with Vanessa, Perry, and Norm.

** Veronica, a (so far) [[OneSceneWonder one episode wonder]] applauded for being a badass who actually prevails over Murphy's Law whether as a babysitter or a pizza delivery girl. Having Creator/DanicaMcKellar as her voice certainly helps.

* TheyWastedAPerfectlyGoodCharacter: There are those who think Isabella could've done more in "The Phineas And Ferb Effect" given how exceptionally skilled she is in a grave situation due to being a Fireside Girl. Instead, she has only two scenes, both near the end, and it's never explained how she managed to help the others survive. The creators admitted that the lack of Isabella was a result of needing to squeeze what would otherwise be a 90-minute story into half the time.

** Scott the Undergrounder and Mildred, a milk carton with a face drawn on it, first seen in Missing Milo.
