** Funnily enough, Bendy. While he's widely hated for being a KarmaHoudini, he was written out of the show as a result of his reception, as well as Lauren Faust's dislike of him because of [[ExecitiveMeddling how the episode came out]]. Many lamented that there should've been a follow up episode where he gets his [[LaserGuidedKarma due deserts]] instead of just abandoning him like that, if only to get the satisfaction of seeing him punished.

** Funnily enough, Bendy. While he's widely hated for being a KarmaHoudini, he was written out of the show as a result of his reception, as well as Lauren Faucet's dislike of him. Many lamented that there should've been a follow up episode where he gets his due deserts instead of just abandoning him like that, making him forever unsatisfying.

* ValuesDissonance
** "Adoptcalypse Now" ends with Mac and Bloo BoundAndGagged as punishment for them doing the same to Wilt. While there were complaints when it first aired, a show made in TheNewTens or after would ''never'' be shown doing this to a child.
** Cheese would be decried today as an offensive caricature of people with learning disabilities due to his spouting non-sequiturs and annoying everyone around him.

* DiagnosedByTheAudience:
** Terrance can be so [[TheSociopath sociopathic]] to the point where it verges on mental disturbance. His behavior also suggests something of a learning disability, as he frequently demonstrates a serious lack of common sense given his age.
** Goo has a common tendency to get distracted, constantly change subjects, and can never turn off her MotorMouth mode. These traits are typically associated with ADHD.
** Bloo might also have ADHD as he has a ''very'' short attention span and is excitable to the max, hardly ever standing still. Having an extremely high-pitched voice and being a {{Keet}} doesn’t help. He also shows signs of autism as he sometimes takes things too literally, appears to take a special interest in paddleballs, briefly treats a rubber elephant toy like a comfort item, and needs to be taught sarcasm despite being a natural. He’s also implied to have a Narcissistic Personality Disorder, as he is often selfish or self-centered and frequently inconsiderate. Then again, mental disorders might not even be a valid concept for an Imaginary Friend, no less one who's only 5 years old.

* IdiotPlot: Another main reason why some of the later episodes aren't so fondly remembered is because if they're not overly mean-spirited, than this trope is at play (though some still have the over-the-top sadism and cruelty at play as well).
** "Duchess of Wails": This episode is a pretty egregious example since everyone whose names aren't Mac, Bloo, Duchess or Terrence suddenly turns into a giant dumbass in the final act. The episode starts with Duchess getting adopted by a family that turns out to be Mac's new neighbors. Duchess' constant dismay over her new stresses Mac's mom out to the point where she wants to move out. Terrence makes Mac believe that they're moving to Singapore ([[GlobalIgnorance which he thinks is in Wisconsin]]) so he teams up with Bloo to vandalize his neighbor's apartment to make them believe Duchess did it so that they can return her to Foster's. When that doesn't work, they just outright kidnap her and return her to Foster's by force. For [[PlotHole no explained reason]], Terrence is somehow able to beat them there despite being slowed down by falling into a pile of wet cement, and tells everybody that they're coming to return Duchess (while purposely leaving out the reason for ''why''). Everybody blindly takes his word and blocks their attempts to get her back in by bombarding them with sharpened carrots and apples among other things. It's only after they've needlessly tortured them that they find out '''''why''''' they were returning her so they take her back... [[CruelTwistEnding on the condition that Mac & Bloo become Duchess' personal assistants and go through the same suffering that everyone else did at the beginning of the episode]]. Extra idiot points for the fact that Terrence [[KarmaHoudini manages to get off scot-free]] for the whole ordeal besides [[DeathGlare a couple of angry glares from everybody]] when they realize they've been tricked and him proceeding to [[ScrewThisImOuttaHere run away]].
*** To make it worse, Duchess herself makes it perfectly clear that she neither wanted to stay with her adoptive family nor go back to Foster's. All they really had to do was free her from the family who adopted her without forcing her to go back to Foster's. So in actuality, Duchess & Terrence are the only ones by the end of the episode who haven't turned into a dumbass.
*** As a bonus: if no one wanted to be with Duchess, why not just abandon her as far away from Foster's as possible? 1. Mac wouldn't have to move, and 2. The Foster household wouldn't ever have to deal with her crap again.
** "Crime After Crime": The whole thing with the episode suddenly suffering from MoodWhiplash in the final act by pointlessly torturing Mac for about two minutes could've been avoided had it not been for this trope. A running gag throughout the episode is that Frankie has to keep making "It" until she gets it right due to the bowl with the "It" in it continuously getting ruined by loose plaster from above falling into the bowl due to people jumping on Madame Foster's bed. The fourth time this happens, it's because of Mac which causes Frankie to come upstairs and forcibly kick him out believing that he's been the one jumping on the bed all day. What follows is about a minute and a half of Mac being chased by the police due to his backpack being full of diamonds that Bloo had placed inside in order to try and get out of having to eat the "It" for dinner. Additionally, the whole mess leading up to that could've very easily been avoided had Frankie just decided to move the "It" bowl after the first time it was ruined.

* SoOkayItsAverage: Although it was a beloved show in its day, it now has this not unearned stigma of being just another run of the mill cartoon from the mid-2000's that didn't break any new ground in terms of animation or writing. That doesn't stop it from having its devoted fans, though.

** Terrance creating and eating a pizza imaginary friend for being a prime example of the pure FridgeHorror of the series’s premise come to life.

** "Challenge of the Super Friends": Bloo's expected to be the bad guy for joining Nemesis, but that only happened after Mac joined forces with Imaginary Man, an imaginary friend he barely knows, and left Bloo to build the treehouse he and Bloo agreed to build.

** Bloo in "The Sweet Stench of Success". Even his haters will admit he didn't deserve the amount of abuse he received in that episode.

** Bloo. Some fans find him very entertaining and funny because of his antics, while other fans find him as an obnoxious {{Jerkass}} who doesn't deserve Mac as a friend, let alone live in Foster's. It doesn't help that he only ever seemed to get ''[[TookALevelInJerkass worse]]'' as the show went on, so much so that by late into the series' run, many fans were wondering why Mac hadn't just up and left him.

* CreatorsPet: Cheese became this for many fans. Ironically, the reason Cheese became a CreatorsPet is because he was [[EnsembleDarkhorse immensely popular]] with the fans in his debut episode. You know what they say; there ''is'' such a thing as [[PanderingToTheBase too much]], well, [[JustForPun cheese]].

** "Beat With A Schtick": Despite the fact that Bloo had every right to be scared that the Big Scary New Guy was going to hurt him badly, none of the other residents (Including [[NiceGuy Wilt]] of all people) side with him simply because he [[DisproportionateRetribution made a bad joke about The Big Scary New Guy's height.]]

** Bloo's alter-egos -- [[TotemPoleTrench Orlando Bloo]] and [[HerCodeNameWasMarySue the Bloo Superdude]].

* MoralEventHorizon: In her second and last appearance, Berry ties up a family and tries to [[spoiler:''kill'' Mac]].

* MoralEventHorizon:
** Although played for laughs, Terrence creating an imaginary friend and then devouring it is without a doubt this, considering the fact that it's the first and only on-screen murder in the entire show.

** It's even more apparent in Terrence's case, who was voiced by the aforementioned Tara Strong. To learn that the actress behind NiceGirl [[WesternAnimation/ThePowerpuffGirls1998 Bubbles]] and DeadpanSnarker [[WesternAnimation/TeenTitans Raven]] also played a unrepentant BigBrotherBully comes off as [[PlayingAgainstType very off-putting]]. Tara Strong has made it clear that [[CreatorsPest she hated voicing Terrence]], which begs the question of why another actor wasn't chosen to replace her, like Creator/KathleenBarr of ''WesternAnimation/EdEddnEddy'' fame.

* VillainDecay: Duchess. She was really only a villainous character in the pilot. After that, she just became snobby and apathetic to everyone around her.

** While Eurotrish is an EthnicScrappy with an annoying singing voice, it's hard not to feel sorry for her in "Foster's Goes to Europe" when Bloo keeps on rudely throwing away her chances to go back to Europe to visit her creator and her creator's parents. Things are especially made heartbreaking by the scene that plays during the credits, where Eurotrish finally makes it to her creator's home only to be harshly turned away.

* IAmNotShazam: No, Foster is not the name of the young male protag. Foster is the last name of the nice old lady who runs the home for imaginary friends.

** For the few people who don't dislike "Everyone Knows It's Bendy," Bloo's ShaggyDogStory is ActuallyPrettyFunny, considering how much of a JerkAss KarmaHoudini Bloo usually is.
