History YMMV / Sixteen

* ValuesDissonance: Canada legalized gay marriage in July of 2005, so "Role Reversal" (which aired in 2010) aired there, no problem; but the US didn't legalize gay marriage in all 50 states until just less than ''10 years later'', which was why the episode was banned from airing in the States.

*** In the pilot episode, when ranting about Caitlin's incompetence, Jen shouts, "I knew I should have hired that weird goth chick!" A few years later, her voice actress would indeed voice [[WesternAnimation/TotalDrama a weird goth chick.]]
*** Kai, the assistant security guard from the episode "The New Kid", is voiced by Drew Nelson, who would later appear in another Creator/FreshTV show as [[WesternAnimation/TotalDrama a character on the opposite side of the law]].
*** In "It's Always Courtney, Courtney, Courtney" Jen complains about how her sister Courtney is the better sister. Jen's voice actress, Megan Fahlenbock would go on to voice Gwen in the Total Drama series, where her legendary rival with that Courtney is because she started dating her boyfriend Duncan.

* ValuesResonance: The fact the show had openly LGBT+ characters in a cartoon that targeted a teen demographic, long before it was accepted by North America as a whole, is still ''very'' progressive.

** In "Quit It" everyone who consumed Nikki's muffins ended up going to the washrooms after she accidentally putted laxatives in said muffins.

* IdiotPlot: "The New Jonesy" has Jen dating a Jonesy clone and being completely oblivious to their similarities. It takes her accidentally kissing Jonesy in [[CoincidentalAccidentalDisguise a wig]] to convince her.

* SugarWiki/AwesomeMusic: The show's theme song.

** Wayne's hatred of [[Film/TopGun Top M16]] becomes this as of 2022 when a sequel to Top Gun, Film/TopGunMaverick, came out and it was even more popular than the original.

* SeasonalRot: Seasons 2, 3 and 4 are considered to be the show's lowest points considering that the episodes of said seasons flanderize the character's personalities and also exaggerated the gross humor in the show. It also didn't help that those seasons constantly reuse character designs to make new characters and have episodes that are blatant remakes of previous episodes.

* FunnyAneurysmMoment: In one episode, a massive food poisoning epidemic hits the mall and the results get played for everyone's amusement. With several ''E. coli'' outbreaks in Canada in the decade that followed, it gets a lot less funny to look at.

* WhatAnIdiot: In the episode "Smarten Up", a woman goes into labour while she is stuck in the change room of the Khaki Barn. Kristen screams for help, at which point Caitlin's current boyfriend, Josh, suggests Jonesy help her, as he believes him to be a gynecologist.\\
'''You'd Expect''': Since the gang had just called the mall's paramedics to save a man who was having a heart attack, they would shoot down the idea and run after the medical professionals to alert them to the new emergency.\\
''' Instead''': Nobody thinks to do this, Caitlin refuses to tell her boyfriend the truth, and Jonesy is forced to deliver the baby.\\
''' Even Worse''': Kristen immediately speaks up and tries to tell Josh that Jonesy is not in college, before Caitlin cuts her off. Hearing the distressed woman scream in agony, Kristen panics and says that Jonesy will do, dragging the untrained, inexperienced teenager to perform a potentially life-threatening medical procedure.\\
''' The Result''': Though the woman miraculously delivers her baby and is shown happily carrying him in her arms afterwards, Jonesy is left traumatized by the event and is hospitalized by the paramedics.

* AlternateCharacterInterpretation: An in-universe example from "The Girls in the Band," regarding a cheesy love song called "My Fantasy," sung by a boy band called [=DawgToy=], which appears to be about a guy who pines for his crush from a distance. While Jen and Caitlin (who're big fans of the group) find the song to sweet and romantic, the boys and Nikki all seem creeped out by it, with Nikki[[note]]Who, in the end, is revealed to be just as much of a [=DawgToy=]-fan as Jen and Caitlin are--if anything, Nikki's actually '''more''' obsessed with the group that either Jen or Caitlin.[[/note]] going so far as to describe the song as "[sounding] like a stalker wrote it."

* WhatDoYouMeanItsForKids: The show aired with a G rating in Canada... and it featured realistically portrayed teenagers. And that means the occasional curse and talk about sex was indeed a part of the show.

** Lydia's entire character, or any other time a person of either gender shows a clingy or obsessive behavior towards their partner, would be very hard to get away with today given the awareness of sexual harassment.
** There are quite a few times where homosexuality is played for comedy. While Canada was much more tolerant of the LGBT community than the US at the time, any attempt to play homosexuality for comedy (even if it is lighthearted comedy) would be banned from cartoons today.

* AmericansHateTingle: When it originally came to the United States, Americans hated the show, and as a result, it failed to gain an audience twice in the States, first on Nickelodeon, then on Cartoon Network. The latter aired the finale, but pulled the show immediately after.

* BaseBreakingCharacter:

* DesignatedHero:

** Nikki's '''''[[NightmareFace REALLY]]''''' angry face when she gives Jonsey a fist in one episode.

* RootingForTheEmpire: In "Employee of the Month", some viewers would have preferred if Nikki stayed a brainwashed clone, because of her [[TookALevelInKindness less abrasive personality]], and [[FansPreferTheNewHer cute new look]].
* TheScrappy:

* ValuesDissonance:
** Canada legalized gay marriage in July of 2005, so "Role Reversal" (which aired in 2010) was justified there; but the US didn't legalize gay marriage in all 50 states until just less than ''10 years later'', which was why the episode was banned from airing in the States.

* VindicatedByHistory: When the show was airing on CN, many fans dismissed it as a less interesting, economy cast take on ''WesternAnimation/TotalDrama'', another Teletoon original which was one of the channel's flagship franchises, despite the fact that this show was made first. Long after the series finale was aired, it has seen renewed interest for having much the same humor and teenage melodrama, but drastically decreased to fit a smaller cast prone to SliceOfLife misadventures. The more grounded tone and cast allowed for consistent characterization, as opposed to ''Total Drama'' which tended to stretch the focus thin to try and have time for everyone. In short, the reasons for its initial dismissal were the same that earned it a solid fanbase and a better lasting reputation.

** This exchange from "The Slow and the Even-Tempered":
--> '''Jen''': But I'm not an astronaut.
--> '''Jude''': No, you're an [[WesternAnimation/TheOctonauts octonaut]].

** In the pilot episode, when ranting about Caitlin's incompetence, Jen shouts, "I knew I should have hired that weird goth chick!" A few years later, her voice actress would indeed voice [[WesternAnimation/TotalDrama a weird goth chick.]]

** Kai, the assistant security guard from the episode "The New Kid", is voiced by Drew Nelson, who would later appear in another Creator/FreshTV show as [[WesternAnimation/TotalDrama a character on the opposite side of the law]].
** The Halloween special revolves around a zombie outbreak at a mall, with the few remaining survivors teaming up to rescue civilians, fighting off the undead with improvised weapons, and trying to figure out a way to escape. The exact same concept would be explored again one year later, when Capcom released the first entry in its famous ''VideoGame/DeadRising'' series.
** In "It's Always Courtney, Courtney, Courtney" Jen complains about how her sister Courtney is the better sister. Jen's voice actress, Megan Fahlenbock would go on to voice Gwen in the Total Drama series, where her legendary rival with that Courtney is because she started dating her boyfriend Duncan.

* TheyWastedAPerfectlyGoodCharacter:
** Some of the one-time characters have never reappeared again.

* HarsherInHindsight: In one episode, a massive food poisoning epidemic hits the mall and the results get played for everyone's amusement. With several ''E. coli'' outbreaks in Canada in the decade that followed, it gets a lot less funny to look at.

* RetroactiveRecognition: Nikki is [[WesternAnimation/RubyGloom Iris]], Jen is [[WesternAnimation/PawPatrol Ace]], [[TheOtherDarrin at least as of Season Three]], and Jude was at one point [[WebAnimation/InanimateInsanity MePhone4]]. For Total Drama fans, Jen is Gwen, Jude is Chris, Wayne is Justin, Chrissy is Courtney, Kirsten is Lindsay and Katie, Kristen is Sadie, and Serena is Leshawna. When taking the ''Ridonculous Race'' SpinOff of the series into account, Nikki is Emma, Jonesy is Don the host, and Chrissy is Ellody, as well.
