History YMMV / AFairlyOddMovieGrowUpTimmyTurner

* WTHCastingAgency: Most glaringly casting Daniella Monet to play a conventionally attractive, glasses-less, adult Tootie.

* JustHereForGodzilla: Quite a few viewers just watch this film for David Lewis's take on Crocker, feeling he brings plenty of energy to the roll compared to everyone else.

* TastesLikeDiabetes: For those who didn't like the movie (and even for some who did), the ending was this and for being a very predictable and ''cliché'' ending.

** Daniella could have easily played a movie-exclusive character who had a crush on Timmy when she was a child. This would also let Monet, a girl who still looked like a teenager despite her actually being in her early 20s able to play someone younger than Drake Bell who looked and actually was 26.

* AssPull: The Timmy Turner Loophole, for some. [[spoiler:Basically, it was created so that Timmy would be allowed to keep his Fairy Godparents even after growing up.]] Even if it was justified [[spoiler:in that Fairy World does owe Timmy big time for saving them on more than one occasion]], it still came out of left field [[ShaggyDogStory and undermined the point of the special, which was to have Timmy grow up.]]

** Some think the movie as a whole is [[ContestedSequel flat-out awful]], and some fans [[SurprisinglyImprovedSequel enjoyed it]].
%% ** The sequels were even more broken. Many saw there being no reason for ''other'' movies.
%% ** Tootie's adult design has torn up the fanbases, especially Tootie fans.

* TaintedByThePreview: There are fans who really dislike the idea of making a traditional ThickLineAnimation series into a LiveActionAdaptation. The few previews that were shown prior to the movie's premiere did little to alleviate those fans' doubts about this project. There are a variety of reasons for this ranging from ''WesternAnimation/AvatarTheLastAirbender''[='=]s [[Film/TheLastAirbender live action movie]] (perceived by people to have been done very poorly) to the fact that there is some ShipSinking along with the fact that Timmy Turner [[spoiler:never grew up and is now a creepy ManChild]]. Even though the movie has now aired, the reaction still is mixed about it.

* TheyWastedAPerfectlyGoodPlot: Timmy being forced to make a difficult decision between finally growing up with the love of his life or continue to live the way he is with the family he loves so much? Sounds like it could have made the perfect finale for the series. But alas, that is not the case.

* NightmareFuel: Hugh J. Magnate's [[spoiler:creepily smiling and giggling evil rabbit.]] Even though it was likely meant as a comical joke, it still manages to be this due to [[spoiler: the high pitched laughter and human face on it, not to mention [[BigLippedAlligatorMoment it came right out of nowhere]], with only Magnate's EvilLaugh probably hinting at it]].

* HarsherInHindsight: [[https://www.sportskeeda.com/pop-culture/what-drake-bell-do-charges-explained-drake-josh-star-pleads-guilty-attempted-endangering-children Drake Bell was found guilty of an incident involving a minor]]. Timmy being played by Drake Bell, the overall theme of growing up with Bell staying a kid, and especially [[https://www.youtube.com/watch?v=uByHusT0pA4 this promo]] for the film where Timmy wishes he was Drake Bell just look uncomfortable now.

* {{Squick}}: A twenty-three year old man acting like a child, even if it is [[spoiler: an act to keep beloved fairy godparents]] is kind of creepy. It becomes even ''more'' creepy when you realize that this ManChild is likely sharing a locker room and bathrooms with [[FridgeHorror other ten year old boys]].

** Cosmo and Wanda's CG designs. Some don't mind them (they were more or less high-definition versions of the models from the ''WesternAnimation/JimmyTimmyPowerHour''), but others would've preferred them done in the show's old style, or anything if they flat-out ''hate'' the CG.

* HoYay: Between Crocker and Magnate.

* UnnecessaryMakeover: The brief flashback to a live-action "young" Tootie is certainly more recognizable to the viewer than the live-action "adult" Tootie.

** The sequels were even more broken. Many saw there being no reason for ''other'' movies.
** Tootie's adult design has torn up the fanbases, especially Tootie fans.

** Some think the movie as a while is [[ContestedSequel flat-out awful]], and some fans [[SurprisinglyImprovedSequel enjoyed it]].

* FanonDiscontinuity: Some fans won't acknowledge it. Aside from perceived quality, a common reason is that it contradicts the DistantFinale of ''WesternAnimation/ChannelChasers'', which shows Timmy indeed maturing and growing up while living a normal life. To fans satisfied with that ending, this comes off as a HappyEndingOverride. This ended up being mitigated as it was revealed it was an AlternateContinuity in the first place considering later seasons of the show would contradict how this movie would even happen in the first place (Poof eventually growing older and going off on his own, Chloe and the whole fairy share deal, etc).

** A [[http://www.nick.com/quizzes/grow-up-timmy-turner-quizzes/one-wish-quiz.html character match-up quiz]] on the official Nickelodeon website strongly suggests that Tootie was the mystery mother of Timmy's children at the end of Channel Chasers, which either added gasoline to an already white hot fiery debate or doused it with a splash of cold water, although some people just prefer not to think of this movie as the real ending to the series, as well as not taking the quiz seriously since this isn't Butch Hartman himself saying it.

It becomes even ''more'' creepy when you realize that this ManChild is likely sharing a locker room and bathrooms with [[FridgeHorror other ten year old boys]]

* EnsembleDarkhorse:
** Some admitted that they liked Magnate's assistant Janice, because she was the only one [[OnlySaneMan who actually questioned what Magnate was doing]].

* MoralEventHorizon: Magnate [[spoiler: trapping Tootie in a cage and using a remote control to ''zap'' Cosmo, Wanda and Poof and drain their energy]] is bad enough, but [[FromBadToWorse it gets worse]] when he [[spoiler: wishes for a bottomless ball pit that he wishes a random mook and Mr. Crocker down. [[DisneyDeath Crocker gets better, though.]] The mook, [[FridgeHorror on the other hand...]]]]

* WTHCastingAgency: Most glaringly casting Daniella Monet to play a conventionally attractive, glasses-less, adult Tootie.

* RomanticPlotTumor: Inverted, if that's even possible. Many people agreed that the romance between Timmy and Tootie is one of the few genuinely good things in this movie, with some wishing that the movie would've focused on those scenes entirely.

* WTHCastingAgency: Some of the cast.

* OneSceneWonder: Jason Alexander and Cheryl Hines as human Cosmo and Wanda, much to the disappointment of many who felt they were much better than the CGI fairies with their TV voices that were used through most of the film.

* FanonDiscontinuity: Some fans won't acknowledge it. Aside from perceived quality, a common reason is that it contradicts the DistantFinale of ''WesternAnimation/ChannelChasers'', which shows Timmy indeed maturing and growing up while living a normal life.
