History YMMV / PhineasAndFerb

* CharacterPerceptionEvolution: Candace was once the show's [[BaseBreakingCharacter most polarizing character]], especially among kids, thanks to her [[BigSisterBully compulsive desire to "bust" her brothers]] regardless of what they're doing, her crush on Jeremy coming across as a borderline obsession, her questionable treatment of Stacy, and her generally acting like a stereotypical teenage brat. However, later episodes would show her softer side by showing [[AwLookTheyReallyDoLoveEachOther she does genuinely care about her brothers]], have her become a better friend to Stacy, and [[TookALevelInKindness tone down some of her more negative traits]]. In addition to this, viewers who watched the show as kids have since grown up and realized that [[JerkassHasAPoint she actually had a point]] in that Phineas and Ferb's crazy inventions could end up hurting someone or themselves (even if she is a bit of a jerk about it), as well as sympathized with her over the fact that she's [[ButtMonkey constantly made to look like an idiot]] and be berated by her own mother, making it understandable she developed an obsession with trying to bust her brothers. All these factors served to make Candace a fan favorite, with many of her former detractors realizing that she wasn't as bad as they thought.

** The ''Doofenshmirtz's Daily Dirt'' webseries commented on current events and pop culture, such as the haul video trend, [[Music/{{PSY}} "Gangnam Style"]], and ''Series/GossipGirl'', that were relevant back when it was active (2013), but are now dated.

* AluminumChristmasTrees: There ''is'', in fact, a not-insubstantial Jewish community of Mexico. They're almost exclusively concentrated in Mexico City and have an old, rich local culture rather than the mashup of Mexican and [[AllJewsAreAshkenazi Ashkenazi Jewish]] culture practiced by the Garcia-Shapiros.

* SeasonalRot: Some fans of the show think the episodes in the first half of the third season weren't ''as'' good.

** "[[Recap/PhineasAndFerbMinorMonogram Minor Monogram]]": [[TheStarscream Rodrigo]] is the new protege of Doofenschmirtz who [[BastardUnderstudy schemes to surpass his mentor]]. Idly pointing out the various cliche flaws in Doofenshmirtz's plans and capture of Agent P, Rodrigo [[EvilerThanThou proves his superiority]] as a {{mad scientist}} by successfully entrapping Perry in a device even the OWCA agent cannot escape. Rodrigo then betrays and imprisons Doofenshmirtz himself, hijacking the man's scheme to hold the Tri-State Area hostage, planning to instead destroy Danville and [[TakeOverTheWorld take over the entire planet]]. Rodrigo's plan is so impressive that even Doofenshmirtz is speechless at his bravado.

** "Remains of the Platypus" might seem this way for people unfamiliar with ''Literature/RemainsOfTheDay'', ''Film/{{Memento}}'' and the backwards episode of ''Series/{{Seinfeld}}'', but even when put in chronological order, the plot is very surreal.

** Major Monogram's [[https://www.youtube.com/watch?v=yant1j9U4L4 brief musical number]] shows up out of nowhere and disappears within ''seconds''.

* EvilIsSexy: Bizarrely enough, ''Doctor Doofenshmirtz'' gets this from a few hardcore fans. It can probably be attributed to his [[TragicVillain ridiculously tragic backstory]] and the fact that [[IneffectualSympatheticVillain nothing ever goes right for him despite how hard he tries]] rather than his actual physical appearance, which is usually seen, at best, as UglyCute.

** The jokes about Dr. Doofenschmirtz being divorced became not so funny in 2023 when the news came out about Dan Povenmire's divorce from his spouse Clarissa.

** Jenny Brown. She has a defined GranolaGirl personality, but her few actual episode roles are just to be Candace's second friend after Stacy. Unlike Django, she never got aDayInTheLimelight that made proper use of her character trait.

** Django Brown. He was treated as a SixthRanger to the main group in "Jerk De Soleil", and then a full episode focused on him with "Oil On Candace"... but then the rest of his appearances are just cameos, and the Sixth Ranger role was filled by Irving.
