History SeasonalRot / TheFairlyOddParents

*** Jorgen Von Strangle went from an intimidating and strict authority figure, who was either an enemy or an ally to Timmy and his fairies, to a PlotDevice whenever the writers needed him to bend around the show's rules. The most notable offender was in "The Big Fairy Share Scare", the premiere of Season 10, where he forces Timmy to share Cosmo and Wanda with Chloe but never offers him an explanation as to why.

** [[WereStillRelevantDammit The overuse of pop-culture references, outdated memes, and 2010s slang in an attempt to pander to the tween audience.]]

* The general consensus is that "Fairly [=OddBaby=]" was the tipping point of the series. [[FranchiseOriginalSin To a minor degree]], some feel the rot started in Season 5, or even as far back as Season 3 when Vicky [[{{Flanderization}} made the switch from a bully of a babysitter to basically Satan in human form]] and for the infamous episode "Twistory", which was outright banned from the airwaves domestically.[[note]]The episode was criticized for its negative depiction of British stereotypes, historical inaccuracy, and UnfortunateImplications that, had the Revolutionary War been lost by the colonists, this somehow means the world would be permanently stuck in the 18th century, technologically and socially.[[/note]]
* Seasons 4 and 5 ''used'' to be this while it was still running due to the {{flanderization}} of a few characters, increasing reliance on mean-spirited humor, and a few bad episodes such as "It's A Wishful Life", a subverted and '''very''' cruel ItsAWonderfulPlot where an unappreciated Timmy wishes he was never born and is shown a world where everyone's lives are better off without him. [[VindicatedByHistory Now, it is widely considered to be a part of the show's "golden age" by many fans]]--except for "It's A Wishful Life", which remains the most despised episode of the show's Golden Age and one of the most despised in general to this day.

*** "Timmy's Secret Wish!", an episode from Season 8 as well as the 10th anniversary special, has him helping Timmy return to Fairy World, only for Crocker to be in the background for the remainder of the episode while concurrently making running gag jokes.
*** "When Losers Attack", also an episode from the same season, has him socially interacting with Foop in a rather positive and friendly manner, despite the latter being an anti-fairy, which is almost the same as the regular fairies. This is a totally missed opportunity for Mr. Crocker to hunt for the anti-fairies in general, which could have allowed for a more interesting and creative plot. The same can be said for Season 9's "Scary [=GodCouple=]", as well as Season 10's "Return of the L.O.S.E.R.S" (the sequel to "When Losers Attack"), "Clark Laser", and "Crockin' The House".
*** "Desperate Without Housewives", an episode from Season 9 as mentioned earlier, has him literally showing up out of nowhere in Timmy's house, as he hangs out with Timmy, Cosmo, and Timmy's Dad after Timmy wishes for all women in the world to disappear for 24 hours.

* Then came along Seasons 7 and 8, where the writers began to slowly [[DemotedToExtra sideline most of the secondary characters]], including Vicky, whose role as the main antagonist was passed on to Mr. Crocker, yet she still appears in the show's intro and outro sequences. According to series creator Butch Hartman himself, this was a deliberate decision as he and the writers favored [[SpotlightStealingSquad Timmy's Dad, Mr. Crocker, and occasionally Foop]] instead. In Foop's case, after his debut in "Anti-Poof", his parents, Anti-Cosmo and Anti-Wanda, were written out of the show with the exception of "Balance of Flour", their last physical appearance in the series. In every episode featuring Foop after "Anti-Poof", neither Anti-Cosmo nor Anti-Wanda are anywhere to be seen. The Flanderization, along with [[SeriesContinuityError continuity errors and inconsistencies, started popping up more around this time as well]] ("Lights Out" and "Timmy's Sercret Wish!" being particularly offenders, with the former criticized for its overly mean-spirited tone and moral, even worse than that of Season 5's "It's A Wishful Life", and the latter backlashed for backstabbing on continuity and slower pacing filled with overuse of gags, especially considering it was otherwise a special supposedly meant to celebrate the show's tenth anniversary). It did not help by the fact many, if not all, episodes since Season 7 were either written or produced by Ray [=DeLaurentis=], who had previously worked on [[WesternAnimation/ShaggyAndScoobyDooGetAClue shows that]] [[WesternAnimation/CoconutFredsFruitSaladIsland weren't well-liked]] to begin with[[note]], and it had only made this worse.

* Seasons 4 and 5 ''used'' to be this while it was still running due to the {{flanderization}} of a few characters, increasing reliance on mean-spirited humor, and the infamous episode "It's A Wishful Life", a subverted and '''very''' cruel ItsAWonderfulPlot where an unappreciated Timmy wishes he was never born and is shown a world where everyone's lives are better off without him.

* While Poof's introduction was the show's turning point, with many claiming that the show relied too much on "whacky baby shenanigans" since then, Season 6 isn't outwardly ''bad'' for the most part as it undid most of the {{Flanderization}} from Seasons 4 and 5. Additionally, not too many episodes revolved around Poof in Season 6, including in the following seasons afterward. As a result, some also consider Season 6 to be the best season in the post-classic era, with some even considering its quality to be the same as the classic era.
* Then came along Season 7, where the writers began [[DemotedToExtra sidelining most of the secondary characters]], including Vicky, whose role as the main antagonist was passed on to Mr. Crocker, yet she still appears in the show's intro and outro sequences. According to series creator Butch Hartman himself, this was a deliberate decision as he and the writers favored [[SpotlightStealingSquad Timmy's Dad, Mr. Crocker, and occasionally Foop]] instead.

In every episode featuring Foop after "Anti-Poof", neither Anti-Cosmo nor Anti-Wanda are anywhere to be seen. [[SeriesContinuityError Continuity errors and inconsistencies started popping up more and more around this time as well]]. A pair of notable examples include:
** "Crocker Shocker" reveals that Crocker's obsession with fairies has been the primary source of Fairy World for a long time, which is a lazy and contrived plot twist on the writers' part. In "Land Before Timmy" from Season 6, Cosmo and Wanda get their magic from electricity, so it seems cruel of Timmy and his fairies to return Crocker to his crazy, socially rejected self when there was an alternative solution to the problem with Fairy Magic anyways.
** "Spellementary School" has Foop attending the same school with Poof, despite the former being an anti-fairy version of the latter, for the sake of forcing a dynamic between the duo. The same trend continued well into Season 8 and onward. The dynamic is by no means any bad, but questions still raise to this day as to why Foop, an anti-fairy, would attend the same school as the regular fairies.
* Seasons 9-10 are wildly considered to be the lowest point in the entire series:

** Season 10 introduced yet another new main character, Chloe Carmichael, as a replacement for Sparky and serves as a new neighbor for Timmy. She has received an even worse reception than Sparky. Many view her as an obnoxious and loudmouthed "little miss perfect" who makes Timmy even more of a loser and whom many feel doesn't meet the requirements for being miserable enough to deserve fairies. [[RescuedFromTheScrappyHeap Her "perfect" traits are thankfully toned down in subsequent episodes, causing some fans to warm up to her.]] That said, she still remains a [[BaseBreakingCharacter divisive character]]. While many fans were delighted to learn [[TakeThatScrappy that Sparky would not be returning to the show]], Season 10 still received its share of criticism. It didn't help that the writing team for the season were new to the industry, or, in the case of Ray [=DeLaurentis=], worked on [[WesternAnimation/ShaggyAndScoobyDooGetAClue shows that]] [[WesternAnimation/CoconutFredsFruitSaladIsland weren't well-liked]] to begin with[[note]]The fact that many, if not all, episodes since Season 7 were written or produced by [=DeLaurentis=] only made this worse[[/note]], nor did it help that there were long hiatuses between new episodes due to failing ratings.

*** Timmy was derailed from a goodhearted child into a selfish, bratty jerk. In Season 10's case, it was to make his status as Chloe's {{Foil}} more obvious to the viewers watching.

*** "Timmy's Secret Wish!", an episode from Season 8 as well as the 10th anniversary special, has him helping Timmy return to Fairy World, only for Crocker to be in the background for the remainder of the episode while concurrently making running gag jokes.
*** "When Losers Attack", also an episode from the same season, has him socially interacting with Foop in a rather positive and friendly manner, despite the latter being an anti-fairy, which is almost the same as the regular fairies. This is a totally missed opportunity for Mr. Crocker to hunt for the anti-fairies in general, which could have allowed for a more interesting and creative plot.

As a result, some also consider Season 6 to be the best season in the post-classic era, with some even considering its quality to be the same as the classic era.

** Various characters from the main cast such as Timmy's Mom, Vicky, and Mark Chang only appeared in episodes if the plot specifically demanded it, with Timmy's Mom becoming just as, if not more stupid than Mr Turner, Crocker, and Cosmo combined.

* The general consensus is that "Fairly [=OddBaby=]" was the tipping point of the series. [[FranchiseOriginalSin To a minor degree]], some feel the rot started in Season 5, or as far back as Season 2 or 3 when Vicky [[{{Flanderization}} made the switch from a bully of a babysitter to basically Satan in human form]] and for the infamous episode "Twistory", which was outright banned from the airwaves domestically.[[note]]The episode was criticized for its negative depiction of British stereotypes, historical inaccuracy, and UnfortunateImplications that, had the Revolutionary War been lost by the colonists, this somehow means the world would be permanently stuck in the 18th century, technologically and socially.[[/note]]

''WesternAnimation/TheFairlyOddParents'', after being UnCanceled several times, has suffered from this harshly, so much so that it has its own page. Eventually, with the departure of show creator Creator/ButchHartman from Nickelodeon, the series was ''finally'' put out of its misery and cancelled for good. Nowadays, the thing that most fans look back on with this show is how much of an example it was of this trope; that it is often brought up as a cautionary tale for future series to be wary of, and unlike this situation with ''WesternAnimation/SpongeBobSquarePants'' (namely the show's time period during Stephen Hillenburg's departure from it following [[WesternAnimation/TheSpongeBobSquarePantsMovie the first movie]]), how [[FranchiseZombie a sharp decline in quality can occur with a show and make it overstay its welcome]] even when its creator remains on board with it throughout its entire run.

*** Mr. Crocker suffers the same flanderization as both Cosmo and Timmy's Dad combined, up to the point that all three of them share an equal [[TooDumbtoLive ungodly level of stupidity]]. Additionally, his obsession with fairies (his defining trait since his debut appearance) is completely gone unless the plot specifically requires it, to the point he no longer has a FreakOut when he sees or otherwise senses something magical nor does he say his famous CatchPhrase anymore. Just three notable examples:

** The sudden shift from the series' traditional use of hand-drawn animation to Flash animation in the last 7 episodes due to their last-minute ordering from the network not giving the animators enough time to have it done hand drawn or properly refine the digital animation. The show had been clearly hanging on loose threads at that point, but for many, this was the point where the show should have been put to rest--and eventually was. In 2017, the show was moved to Nicktoons where it aired out its final episodes, with the last one airing in July of that year, followed by Butch Hartman leaving Nickelodeon several months later in February 2018.

** Season 9 introduced [[TheScrappy Sparky]], who serves as the new mascot for Timmy, and has received negative reactions. Besides Sparky himself, continuity was apparently abandoned by this point ("Let Sleeper Dogs Lie" being a particular offender due to retconning the events of "The Origins of Denzel Crocker" from Season 3) and [[RecycledScript episode plots became way too generic and unoriginal due to often rehashing older plots]] ("Desperate Without Housewives" being a particular offender due to reusing the plot of "Love Struck!" from Season 3, an episode that also wasn't well received to begin with). The same trend continued well into Season 10. Additionally, while the new HD intro (with the animation redrawn and Poof added in) is passable, Vicky's headgags are all just reused versions of those found in Season 1, with the exception of the Sparky headgag.
