* AlternativeCharacterInterpretation: The show itself is SoBadItsGood but to which extent this is [[SpringtimeForHitler intentional]] is debatable.
* AmericansHateTingle: This show has quite the vocal {{Hatedom}} in the United States, especially since Canadian cartoons in general tend to do poorly in the USA anyway. The fact that it is {{Adored by the Network}}(despite getting terrible ratings) has been major fuel for it.
** But this show is hated even in Canada it would surpass the hatred of it in the US.
* {{Anvilicious}}: Morals are dropped... [[{{Understatement}} hard]]:
** The worst offender is Johnny Applesauce, with its "petitioning is better than violence" [[AssPull Ass Pulled]] {{Aesop}} despite the show itself being action-packed.
** Similarly, "Green Johnny" comes off less like an episode, and more like an 11-minute [[PublicServiceAnnouncement [=PSA=]]] about [[GreenAesop recycling and going green]].
** Also, "Good Ol' Johnny Test" starts off as a parody of ''WesternAnimation/ACharlieBrownChristmas'', but becomes quite {{Anvilicious}} once the play turns into a big GreenAesop about waste management.
** Lampshaded, averted and subverted in later seasons [[note]](with the exception of ''X-Ray Johnny'', where the "Books are knowledge, and knowledge is power" message is hammered in once a minute with no irony in sight; even ''Johnny Applesauce'' pales in comparison.)[[/note]].
* {{Asspull}}: In "Johnny's 100th Episode" Mr. Mittens and Dark Vegan's reasons for wanting Johnny to come out of his coma come completely out of nowhere. At least Bling-Bling Boy has gotten along with Johnny occasionally.
* BileFascination: Some people watch it because of how shoddy it is.
* BrokenBase: The show does have its fans considering it has seven seasons due to having some actually good dialogue, parental bonuses, and admittedly some clever plot lines; but, due to overexposure from its respective networks, stagnant character development, way too much focus on Johnny (who many think to be unlikable), and poor animation in the later seasons, many have likewise taken a hating for it. Not to mention that anti-fans believe that Canadian laws that require Canadian-only programming in their television stations is the only reason why it lasted so long.
* ClicheStorm: This show is criticized for rehashing a lot of stock cartoon plots, including ''its own''.
* CriticalResearchFailure: Mostly for the sake of RuleOfCool and RuleOfFunny.
* CriticProof: Considered one of the worst cartoons ever made. Ran for '''seven seasons'''. We have the Canadian government to thank for that.
* [[SugarWiki/AwesomeMusic Crowning Music Of Awesome]]: Dukey's Johnny Applesauce Song.
* DeaderThanDisco: Believe it or not, ''WesternAnimation/JohnnyTest'' was actually fairly popular during its first few years (having a higher budget and completely different production team probably helped). Now it's one of the most hated cartoons ''of all time''. The only reason it's still running is apparently because of a Canadian law forcing Canadian animation to be constantly churned out (the show's ratings are abysmal). It's very telling that its season boxsets are sold solely in ''bargain bins''.
** Even Creator/CartoonNetwork seems to despise it as almost all of their promotions for it reek of OurProductSucks. It's even believed that the whole show was a SpringtimeForHitler ploy GoneHorriblyWrong.
* DesignatedHero: One of the main flaws of the show, especially for the fans themselves, is that it's nearly impossible to root for Johnny sometimes.
* EnsembleDarkhorse:
** Dukey is popular even among the hatedom.
** Sissy is popular with the fans (especially shippers).
** Mary and Susan, who many people see as the genuine main characters.
* EscapistCharacter: Johnny's clearly meant to be this for the show's target audience; it... doesn't really work.
* EvilIsSexy: Or Cute at very least. Susan and Mary as vampires as well as their faux supervillain personas.
* FanonDiscontinuity: Most of the fandom considers it a "Season 1 only" show.
* FoeYay: Bumper does this with Johnny a lot, whether Johnny is [[UnsettlingGenderReveal crossdressing]] or not; another example was in an episode where Johnny tries to change his personality in one of his sister's machines and, when he's stuck a smooth-talking British personality, Bumper implies to like this version of him a lot.
* HilariousInHindsight: Using the "Superhero Effect" to win Susan's heart is a plot reminiscent of the "Mary Jane loves Spiderman" storyline. [[OneMoreDay A storyline kicked out of the canon.]] Same goes for a comparison to "Lois Lane loves Superman", given the CosmicRetcon in ''ComicBook/{{Flashpoint}}''.
** Johnny and the Mega Roboticles. If being the first cartoons to spoof "Toy/{{Bionicle}}" wasn't enough, it became a lot funnier when an [[ShoddyKnockoffProduct actual Bionicle bootleg called "Roboticle"]] [[http://www.otca.com.au/boards/showthread.php?t=2726&page=5 was spotted on store shelves.]]
* HoYay:
** Gil is noticeably always excited to see Johnny; yet when he sees Johnny's sisters, he can't even remember their names. To make matters worse, in a episode is revealed that in his personal POV of the world, girls don't exist.
** Mr. Black and Mr. White, whose HoYay is kind of blatant.
** In the episode "Johnny [=McCool=]", at the end of the episode the twins are seen sighing at Gil eating a sandwich, then pans out to Gil sighing at Steve [=McCool=], and it turns out it is a picnic. [[spoiler:However the [=McCool=] presented is Dark Vegan in disguise.]]
* IdiotPlot: There are a few episodes subjected to it here and there.
* IronWoobie: Dukey is pretty much this, still having his cheerful, lovable sense of humor despite being a ButtMonkey.
* ItsTheSameNowItSucks: Some fans are annoyed at the lack of character development in later seasons.
* JerkassWoobie: Susan may be a bitch but she has a lot to put up with.
** From the Smarty Pant's point of view, Johnny is a BastardBoyfriend, who only uses them to impress another girl.
* LoveItOrHateIt: To put it mildly, the show has a rabid fanbase and lots of haters, with virtually nothing in-between; the show being AdoredByTheNetwork doesn't help.
* MarySue: Played with because of Mary and Susan Test, whose names are based on the TropeNamer.
** MartyStu: But Johnny Test himself (post-season 1) is a Marty Stu of proportional levels.
* MemeticMutation: '''WHIPCRACK''' and ''guitar riff'' because of how the show abuses these two sound effects every chance it gets.
** Johnny Testing my FUCKING PATIENCE!
* MostAnnoyingSound:
** The whip sound effect that happens whenever someone lifts their arm; also, [[http://www.youtube.com/watch?v=8WXbJ_uB338 most of the other sound effects]], due to how out-of-place they are.
** The amount of screaming makes this show hard to watch for viewers with sensitive hearing; the number of screams is high enough to qualify as [[TVTropesDrinkingGame drinking game]] material, although [[ShmuckBait a dangerous one]].
* {{Narm}}: Rampant [[SeasonalRot after the first season]]; [[SoBadItsGood sometimes goes with the]] NarmCharm.
* OneEpisodeWonder: Vampire Susan and Mary, especially among the anti-''Literature/{{Twilight}}'' fans.
* OneSceneWonder:
** She-Johnny appeared for about a second in the very first episode, but that was enough to grant an awful lot of fanart; in fact, look it up on Website/DeviantArt or a related site.
* PeripheryDemographic: Due to Dukey and, well, [[UsefulNotes/FurryFandom furries]].
* TheScrappy:
** Johnny. Yes, the main character, for most viewers (fans and haters alike). He can be very whiny or despicable at times and yet we're supposed to constantly root for the guy.
** Also, Johnny's dad for being such an authoritarian to his family; even the writers [[ChewToy don't seem to like him a lot.]]
** Bling Bling Boy to some as his pining for Susan is a lot more creepy than funny.
** Pretty much everybody who's not an EnsembleDarkhorse is seen as a Scrappy to some extent.
* SeasonalRot: Season 1 was SoOkayItsAverage despite the potential it showed, but things went downhill in Seasons 2 and 3 (although enjoyable due to their SoBadItsGood value). Season 4 saw a slight improvement, but by then, the damage was already done and ''Johnny Test'' lost more fans and ratings with every season.
* SnarkBait: Due to the already mentioned SoBadItsGood aspect.
* SoBadItsGood: Admittedly, more than a few fans will admit this.
* SoOkayItsAverage: Likewise a conclusion to some. Not a bad show, but nothing really special about it either.
* {{Squick}}:
** Johnny and Sissy look like siblings. Aside from that most likely unintentional instance, there's the writers' apparent fondness for ScrewYourself and everything related to it.
** The scene after the beginning minutes of "Johnnyitis" in which Johnny, desperate to become sick in order to have an excuse to miss a big history test, eats a sick woman's ''used tissue''. Said woman also had ''snot draining from her nose.''
* SuspiciouslySimilarSong: [[https://www.youtube.com/watch?v=bmg-fnE7Das The show's theme song]] to Music/GreenDay's [[https://www.youtube.com/watch?v=Ee_uujKuJMI "American]] [[Music/AmericanIdiot Idiot"]].
* TheyChangedItNowItSucks:
** As of Season 5, Dukey [[TheOtherDarrin now has]] the same voice actor as Johnny's dad, which proved an unpopular decision at best; the same goes for the change of Mary's voice actress.
** Season 2 is this, but that's mostly due to some fans being put off by the shift in animation after Season 1; compared to ''WesternAnimation/{{Cyberchase}}'' and ''WesternAnimation/{{Caillou}}'' which had done similar but only after 4 seasons, this show at least had the common sense to switch early.
*** Though sadly by Season 5, the animation got even worse than before.
* TheyCopiedItSoItSucks: The show shares more than a few similarities to ''WesternAnimation/DextersLaboratory'', and over time, people started to notice:
** Susan and Mary Test are obviously the Dexters of the show, being redheaded genius children with a laboratory in their house.
** Johnny is like Dee Dee, since both of them are DumbBlonde annoyances who constantly cause trouble for their genius siblings.
** Their parents are kind of like if one took Dexter's mom and dad and swapped their personalities, and then flanderized them: Johnny's Dad is a major neat-freak, while Dexter's Mom had her moments of this as well; Johnny's Mom is the head of the house and always working, while Dexter's Dad was just the head of the household.
** Also, a female in the main cast is bothered by an AbhorrentAdmirer, who is another nerdy genius child with their own laboratory; Bling-Bling Boy is the Mandark of the show.
** Dukey can also be compared to Monkey, both being animals who have gained unusual abilities because of the genius children, Dukey's being talking, while Monkey becomes a superhero.
** Let's not forget, there was also an episode of Dexter's Lab called "Dexter's Lab" in which Dexter finds a lost dog which he teaches to speak English.
** Not helping the show's case, the concept for Johnny Test was supposedly created in 1995, in other words, shortly after the first episode of Dexter's Lab aired in February 1995.
* TheyJustDidntCare: The only plausible explanation for the show's low quality.
* TheyWastedAPerfectlyGoodCharacter:
** What non-fans tend to think of Dukey.
*** Same for Mary and Susan.
** Essentially, major characters get this treatment in favor of Johnny.
** TheyWastedAPerfectlyGoodPlot: due to the above-explained reason, and the borderline lack of ADayInTheSpotlight for supporting characters.
* UncannyValley: Speed [=McCool=] and Monkey; although that's probably intentional.
** The DerangedAnimation (starting in season two and getting worse from there) and bizarre, strangely exaggerated facial expressions (along with most characters' lack of pupils) are surprisingly unsettling; none of this is helped by the unappealing (or just plain ugly in some cases) character designs.
* WereStillRelevantDammit: There's a noticeable amount of perceived desperation to appeal to kids (most episodes' titles [[ItsAllAboutMe have Johnny's name in them]]), appalling most people.
** Probably the worst example of this would be the Website/YouTube (or rather, [[BlandNameProduct "Snoobtube"]]) episode... in 2010.
*** In fact, looking up the website redirects you to Nick.com.
* WhatAnIdiot: Johnny's idea to replace toy cereal prizes with real, lethal laser guns for kids in Johnny-O's isn't a good idea. And that's the tip of the iceburg for Johnny's schemes.
* TheWoobie:
** Dukey, who always seems to get frozen in a block of ice or turned to stone. Also, the episode "Bathtime for Johnny" where Johnny "forgot" his birthday and he sobbed his heart out for nearly the whole episode (see TearJerker above). Last but not least, most people go out of their way in the show to point out how ugly he is.
** Mary and Susan, on occasion.
