History YMMV / TheAdventuresOfJimmyNeutronBoyGenius

** King Goobot crossed it in the PilotMovie when [[spoiler:he reveals the parents of the kids are going to be sacrificed to Poultra, and how it's all Jimmy's fault because of Jimmy's transmission]].

* UnintentionalUncannyValley: While the CGI is actually fairly good for the standards of early 2000s cartoons, it hasn't aged all that well. The character designs aren't very optimized for the snappy, cartoony movement that the animators were shooting for, which is especially apparent when [[http://vignette1.wikia.nocookie.net/jimmyneutron/images/5/58/Vlcsnap-2016-06-03-22h57m50s741.png/revision/latest?cb=20160604042015 their mouths]] [[https://vignette3.wikia.nocookie.net/jimmyneutron/images/d/d2/I_Love_You_Cindy_Vortex.PNG/revision/latest?cb=20170311123816 open too wide]].

-->'''Jimmy''': Um... I sense a disturbance in my pants, ma'am.

--->'''Jimmy:''' Libby, ''quick'', I need you!
--->'''Libby:''' ''(Surprised and Flattered)'' Why Jimmy, this is so sudden.

--> '''Jimmy:''' Sheen, remind me to remove what's left of your brain later.[[note]]Basically, he intends to give Sheen a lobotomy.[[/note]]

-->'''Jimmy''': Stand still. I'll find my torch.\\

* VindicatedByHistory: When it first aired, many slammed the show for being [[TheyCopiedItSoItSucks too similar to]] ''WesternAnimation/DextersLaboratory'', and the humor being SoOkayItsAverage (just look at some of [[http://www.imdb.com/title/tt0320808/reviews?start=0 these reviews that were written when the show was initially aired]]). However, since being off the air for several years now and [[WebAnimation/JimmyNeutronHappyFamilyHappyHour a certain infamous fan animation]] reminding people of the series, people have since rediscovered it and given it a second chance and realize how the show had its own identity. Nowadays, it's often hailed as one of the best Nicktoons ever.

** For [[CrossOver Jimmy/Timmy Power Hour 3]], which was originally was supposed to be a GrandFinale for [[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius both]] [[WesternAnimation/TheFairlyOddParents shows]]. Who didn't want to see a 3D Dimmsdale and a 2D Retroville, Crocker or the alien Mark Chang in 3D? And better yet, send the Gigglepies to Retroville and the Twonkies to Dimmsdale (we wonder if Timmy has learned from the Gigglepie experience?). This was mainly due to DNA Productions shifting down at the time, so they couldn’t create 3D models of all the Fairly Oddparents characters.

** Baby Eddie reveals his true malice and plans on killing off the entire Neutron family in order claim the family money for himself.

** Despite [[WesternAnimation/PlanetSheen his infamous spin-off]], Sheen ''does'' still some fans who find him funny (in the movie and the original show, anyway), helps that said spin-off was quietly cancelled after quickly losing its relevance.

* DiagnosedByTheAudience: Sheen is prone to [[MoodSwinger wild mood swings]], has [[AttentionDeficitOohShiny a low attention-span]], [[CannotTellFictionFromReality has trouble differentiating fiction from reality]] ([[BelievingTheirOwnLies even if he is a contributor to that fiction in some way]]), [[LoonyFan his obsession with Ultra-Lord goes beyond a passionate hobby]] and whatever he has, he apparently takes medication for it.

** Jimmy. He means well, but almost nobody likes him or his inventions (we eventually realize that not even his '''own relatives''' (aside from his parents) want anything to do with him). There may be a good reason for that, since he can be a rude, arrogant, condescending, know-it-all InsufferableGenius with a LackOfEmpathy, especially in Season 3. It doesn't help the fact that many of his inventions have endangered the lives of ''hundreds of people'' in Retroville. No wonder why the guy made so many enemies throughout the course of the series. Though to be fair, most of them either end up, or were ''already'' worse than him. Good examples of his Woobie-ness have to be in "The N-Men", "Normal Boy", "The Incredible Shrinking Town", and "Jimmy Goes to College."

* CriticalResearchFailure: Happens all the time, courtesy of RuleOfCool and lazy writing. Kinda surprising, considering how smart Jimmy is. For one thing, Jimmy has stated that Australia is a country, not a continent (it is both). He could've just been bluffing and trying to make up an excuse to argue with Cindy.

** Bolbi, due to his memetic "Slap Slap Slap, Clap Clap Clap" dance and {{Theatre/MacBeth}} monologue.

* DiagnosedByTheAudience: Sheen is prone to wild mood swings, has a low attention-span, has trouble differentiating fiction from reality (even if he is a contributor to that fiction in some way) and whatever he has, he apparently takes medication for it.

** Courtesy of "Men at Work" - don't drag people (especially your ''partner'') somewhere they've repeatedly said they don't want to go, especially if it's because they already had plans to go elsewhere. Even without the [[SpaceWhaleAesop fully-computerized restaurant pulling a HAL 9000]], it pretty much guarantees nobody's going to have a good time.

** Carl Wheezer. His haters don't like him primarily because he came off ''really'' annoying with his weird feelings in Judy, his weird fixation with llamas and his whining. It didn't help his character TookALevelInJerkass later on. On the other hand, others at least find him likable and funny and try to get past the episodes such as "Carl Wheezer: Boy Genius".
** Cindy Vortex. While most people think she’s Jimmy’s soul mate, some think Cindy's {{pride}} is no excuse for how she treats Jimmy and his friends. This is when people really miss how more sympathetic and friendly she was in the movie. Some of the most infamous examples of the detractor's ire go to "The Incredible Shrinking Town", "Vanishing Act", "The N-Men", "King of Mars" and her Valentine song.

* BetterOnDVD: Season 3 counts as such. When it first aired on TV, viewers were left confused over the sudden lack of continuity between episodes, and it was initially considered to be a case of SeasonalRot. When season 3 was released on home media, it was discovered that, when the show started becoming more continuity-driven, the episodes were aired ''out of order'', meaning that almost all of the odd continuity was completely unintentional.

** "I Dream of Jimmy" features some ''really'' absurd humor and bizarre scenes. Justified - the bulk of the weird happens inside Carl's dream.

* CharacterPerceptionEvolution: Skeet, from the memetic episode "Men at Work", was intended to be seen as something of an idiot and a disrespectful manager to Jimmy, with kids watching the episode and taking Jimmy's side. The discourse changed once the fandom grew up, many of these kids taking minimum wage jobs for themselves, and beginning to realize that not only was Jimmy being a bit of a brat, but everything Skeet said was entirely correct. In this light, Skeet has become an EnsembleDarkhorse often depicted as an OnlySaneMan.

* EthnicScrappy: Elke, Carl’s Swedish pen pal in "Carl Wheezer: Boy Genius". She’s a dumb blonde, has a silly accent, speaks broken English and doesn’t seem to care that Carl nearly got her and everyone else killed. Thankfully, she only shows up in one episode.
* EnsembleDarkhorse:

* FanficFuel: Imagine what you can do with Jimmy's HypnoRay--or any of his inventions.

* FranchiseOriginalSin: Jimmy had a problem throughout the series of being arrogant, abrasive and causing at least half the problems of the show. But he also had many sympathetic qualities, worked to fix these problems and was called on this actions to counterbalance it to make him a relatable, likeable, yet flawed character. When ''WesternAnimation/PlanetSheen'' rolled around, Sheen had the same problems, but none of the redeeming qualities nor was he called out for his actions, causing many of the complaints people had with that show.

** The evil clone from “Send In The Clones” resembles a certain [[WebAnimation/EddsWorld red-hoodie wearing Norwegian.]]

** Bolbi's developed this relationship. So has Hugh, for that matter - fanart of him as a musclebound [[Manga/FistOfTheNorthStar Kenshiroesque]] anime badass has become surprisingly popular.
** Hugh Neutron has become an extremely powerful [[Anime/YuGiOh denizen of the Shadow Realm,]] sometimes dragging people into it when they go into dark places, such as...[[FelonyMisdemeanor Incognito Mode.]] As the icing on the cake to this, Hugh Neutron's voice actor, Mark [=DeCarlo=], actually [[https://twitter.com/csd_was_taken/status/1416869414859902992 voice acted the meme when he was asked to do it on Twitter]]. And Hugh has been announced as a playable fighter in ''VideoGame/NickelodeonAllStarBrawl'', while his son and main character remains nowhere to be seen.
* MemeticMolester:
** Carl is treated like this with his [[AbhorrentAdmirer creepy]] obsession with Judy. Most famously, when he had [[WesternAnimation/TheFairlyOddparents Wanda]] (who herself was creeped out) turn Professor Calamitous who's trapped in a small bottle into a miniature copy of Judy at the end of ''Jimmy Timmy Power Hour 2: When Nerds Collide'', and Calamitious reacted to him in horror.

** Evil Jimmy starts off as a simple prankster at first...up until he creates an evil version of Jimmy's planet and attempts to destroy the old one and forces Jimmy to watch, and trap him in his world of darkness.

** Later on, he demoted Jimmy down to simply advertising the store out front because he called salt "sodium chloride". While this is meant to show Skeet as too stupid to understand that "sodium chloride" and "salt" mean the same thing (as evidenced by his reasoning for demoting Jimmy being that the latter ''doesn't'' know what salt is), most people don't refer to salt as Sodium Chloride in a non-chemistry context. In fact, those who do refer to it by its scientific name in normal conversation tend to come off as a pretentious jackass - like Jimmy does.

** Dr. Sidney Moist. He was incredibly crazy and hammy, but only had one episode in season 3 (and a cameo in the third ''Jimmy/Timmy Power Hour''). It would've been hilarious to see more of him for sure.
** Another villain with wasted potential was Yoo Yee. Like Dr. Moist, he was very hammy and only appeared in one season 3 ep. It would've been neat to have him as a recurring villain (and basically be Sheen's arch-enemy).

** Brittany, since Cindy and Libby often brush her off and pick on her when she tries to be nice to them. Sweet, underconfident, innocent and kind to everyone, Brittany is just that one character you wanna hug when things go wrong for her.

*** Speaking of the latter episode, the music playing during Sheen's training montage has a very similar tune to Kung Fu Fighting by Carl Douglas. A variety of Music/{{Survivor}}'s "Eye of the Tiger" can be heard at one point (which it also does in "Birth of a Salesman").

* UncannyValley: While the CGI is, by all means, decent for the standards of early 2000s computer-animated TV shows, it hasn’t aged very well. A lot of the character designs get pretty ugly looking at times, like when [[http://vignette1.wikia.nocookie.net/jimmyneutron/images/5/58/Vlcsnap-2016-06-03-22h57m50s741.png/revision/latest?cb=20160604042015 their mouths]] [[https://vignette3.wikia.nocookie.net/jimmyneutron/images/d/d2/I_Love_You_Cindy_Vortex.PNG/revision/latest?cb=20170311123816 open too large]].

* ArousedByTheirVoice: Beautiful Gorgeous. Creator/WendieMalick really found her [[Franchise/JamesBond inner Bond girl]] when portraying her, giving Gorgeous [[ContraltoOfDanger a sensual, breathy voice]] befitting such a voluptuous [[TheVamp vamp]]. Many a viewer have paid extra close attention whenever she plays up the seductive tone.

%%* EvilIsSexy: Invoked and parodied with Beautiful Gorgeous.

* BaseBreakingCharacter:

** If we're counting his inventions, then Jimmy's Hypno Beam/[[SuddenNameChange Ray]]. Yes, ''[[TropeNamer that]]'' HypnoRay. People love to make fanart and fanfiction of what they could do with that thing.

** Despite [[WesternAnimation/PlanetSheen his infamous spin-off]], Sheen ''does'' still some fans who find him funny (in the movie and the original show, anyway), helps that said spin-off was quietly cancelled after quickly losing it's relevance.
