History SeasonalRot / TheFairlyOddParents

** The {{Flanderization}} of several characters: Timmy was derailed into a selfish (and bratty) jerk once again to make his status as Chloe's {{Foil}} more obvious, Chloe went from an excitable but relatively grounded girl to being constantly hyperactive and prone to frequent bouts of hysterics and histronics, Cosmo and Wanda [[TookALevelInDumbass took several levels in dumbass]] and were constantly rendered helpless and unable to help Timmy and Chloe due to them [[RunningGag losing their wands in every episode]], Timmy's Dad went from a BumblingDad to a LethallyStupid {{Manchild}} who causes destruction wherever he goes, and Crocker's obsession with fairies (his defining trait since his debut appearance) was completely gone unless the plot specifically required it, to the point that he no longer has a FreakOut when he sees something magical nor does he say his famous CatchPhrase anymore. The Season 8 episode "When L.O.S.E.R.S. Attack" has him being best friends with Foop despite the latter being an Anti-Fairy.

** While on the topic of the theme song, there was also [[https://m.youtube.com/watch?v=D56T-r3Dz28 the show's intro and theme song]] being changed to reflect the new season. Many feel that the new version of the theme song is inferior to the original due to having just two people singing instead of a full chorus and lazily pasting together clips from episodes of the season. At first it seemed that [[AuthorsSavingThrow the producers had caught on to the complaints and used the original intro in the episode "Girly Squirrely"]], but it only lasted for two episodes as from "The Fair Bears" onwards they began using the new intro once again.

* With the departure of Butch Hartman from Nickelodeon, the series was ''finally'' put out of its misery and cancelled for good.

* Seasons 4 and 5 ''used'' to be this while they were still running due in part to the {{Flanderization}} of some of the characters and the infamous episode "It's A Wishful Life", a twisted and '''very''' mean-spirited ItsAWonderfulPlot where an unappreciated Timmy wishes he was never born and is shown a world where everyone's lives are better off without him. Now they are considered to be a part of the show's "golden age" by many fans. That said, "It's A Wishful Life" remains the most despised episode of the show to this day. Even the creator of the show, Creator/ButchHartman, hates this episode.

''WesternAnimation/TheFairlyOddParents'', after being UnCancelled several times, has suffered from this harshly, so much so that it has its own page.

* Season 10 was considered by many fans to be the lowest point of the series. Coincidentally, it was also the last season before the show was cancelled for the final time. While many fans were delighted to learn [[TakeThatScrappy that Sparky would not be returning to the show]], it has 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 legitimately]] [[WesternAnimation/CoconutFredsFruitSaladIsland bad]] cartoons.[[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. Reasons included:

* The general consensus is that "Fairly [=OddBaby=]" was the tipping point of the series. To a lesser degree, some feel the rot started sometime after "Channel Chasers", 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 heavily criticized and subsequently banned from the airwaves for its negative depiction of British stereotypes and historical inaccuracy.

** The sudden, mid-season shift from the series' traditional use of hand-drawn animation to Flash animation.
** The deterioration of the show's writing causing [[RecycledScript episode plots to become unoriginal and so generic and often being rehashes of plots from the show's previous seasons]] along with [[SeriesContinuityError the previous season's continuity errors and problems]].

* While most agree that Poof's introduction was the show's turning point, many believe Season 6's episodes aren't outwardly ''bad'' for the most part as it undid most of the {{Flanderization}} of Season 5. Then Season 7 came along, when the writers began [[DemotedToExtra forgetting about side characters]] and [[SpotlightStealingSquad focusing only on Crocker and Timmy's Dad]].

* Season 9 -- the season where [[TheScrappy Sparky]] is introduced -- has received a negative reaction. Besides Sparky himself, continuity errors started popping up more and more around this time ("Let Sleeper Dogs Lie" being one of the worst offenders).

** The addition of ''yet another new main character'' named Chloe that Timmy must share his fairies with, who many view as an obnoxious Little Miss Perfect who makes Timmy even more of a loser and who 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]].

The Season 8 episode "When L.O.S.E.R.S. Attack" has him being best friends with Foop despite the latter being an Anti-Fairy.

** Poof's perplexing and inexplicable absence from the season. While Sparky being dropped from the show was confirmed by his voice actor, Poof is nowhere to be seen due to difficulties with having too many main characters in a plot. This is made all the more strange by the fact that Foop, Poof's EvilCounterpart, appeared in the season's ''very first episode'' and continues to make appearances throughout the season, even starring as the main villain in the episode "Blue Angel". Also, in both the old and new intros, Poof is still there. Poof finally appeared in the episode "Certifiable Super Sitter".
