Americans Hate Tingle: Americans hate this show because of its gross humor. 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.
Nikki is one in "Over Exposed" after Chrissy quits. Although we're supposed to believe that she's a good guy, her insulting of customers for no reason without her co-workers to stop her (and their eventual joining in) combined with the fact that she brings them to Chrissy to brag about how she's become their controller (ironic, since she thinks of herself as a free-thinking rebel) pretty much cement her as an example, at least for one episode. The comparison gets more ironic when Chrissy actually gives up her nice job to prove The Power of Friendship.
Ear Worm: ''I'm 6teen, starting to find my way... got a new job, gonna start at the mall today!"
Ensemble Dark Horse: The Clones (Nikki's coworkers at the Khaki Barn) are pretty popular characters, with Kristen (the green-eyed one with long hair pushed back with a headband that's blue with red polka dots) being the most popular.
Girl-Show Ghetto: Airs exclusively on PopGirl in the UK despite being a unisex show.
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 a weird goth chick.
Count all the teenagers that turn into zombies in "Dude of the Living Dead", and then watch the first episode of Gravity Falls where they compare teenagers to zombies.
Idiot Plot: "The New Jonesy" has Jen dating a Jonesy clone and being completely oblivious to their similarities. It takes her accidentally kissing Jonesy in a wig to convince her.
Wyatt's ex-girlfriend, Serena, is definitely this: text message thing aside, breaking up with a Nice Guy like Wyatt (for a largely superficial reason) just to get back together with her ex (a guy's who arguably/ironically way less mature than Wyatt is—and who also felt it was pretty low of Serena to break up with Wyatt via text message) didn't exactly go over well with fans. And neither did Serena's Clingy Jealous Girl-antics towards Wyatt after he finally got over his feelings for her and moved on to other girls (nevermind the fact that she was the one who dumped Wyatt in the place).
Jude's ex-girlfriend, Starr, is this (although perhaps to a lesser extent)—she became Goth all of sudden and broke up with Jude for largely superficial reasons (although she at least admitted that she still cared a lot about Jude). It got worse after she adopted a nerd-persona and became an Insufferable Genius—she decided not to pursue a relationship with Jude after deeming not to be "intelligent enough" for her (she claimed that a person has to have an IQ of at least 130 to join her new nerd clique), but it later turns out that Jude actually has an IQ of 175.
Diego and Robbie Garcia, Jonesy's two younger brothers. The two are majorly annoyingJerkasses who do incredibly stupid things that would, in real life, get them into a lot of trouble, and possibly even killed in some cases. Overall, the two of them are just very unpleasant.
Tear Jerker: The show's two-part series finale. Nikki's dad gets a new job. This would normally be a happy moment, but the new job means Nikki has to move away. The ending montage is especially sad.
Values Dissonance: For instance, Canada legalized gay marriage in July of 2005, so "Role Reversal" was justified there; 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.
Vindicated by History: When the show was airing on CN, many fans dismissed it as a less interesting, economy cast take on Total Drama, another Teletoon original which was one of the channel's flagship franchises. Nowadays, long after the series finale was aired, its seen renewed interest for having much the same humor and teenage melodrama, but drastically decreased to fit a smaller cast prone to Slice of Life misadventures. The more grounded tone and cast allowed for consistent characterization, as apposed 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.
