* BrokenBase: The movie, which has a villain that tried to and succeeded in taking Clifford away from Emily Elizabeth, and an large heaping dose of MoodWhiplash thanks to Jody Gray's contribution that is an extremely depressing soundtrack. Part of the fanbase loved the emotional roller coaster. Part of the fanbase (which wanted a happy romp around Birdwell Island and nothing more) thinks it sucked because of being put through emotional roller coaster.
* EarWorm:
** The [[http://www.youtube.com/watch?v=nWwIyKOCrd8&feature=fvst theme song to the cartoon series]].
** A lot of the background music could also fall in this category.
** For anyone who remembers the '80's direct-to-video series, its theme song also counts. [[https://www.youtube.com/watch?v=wkxFYavvq1Y Take a listen]].
* FirstInstallmentWins:
** You'd be hard pressed to find anybody who watched or even remembers there being a spinoff. The fact that it was put on a once-a-week time slot probably did not help.
** Inverted with the 1980s direct-to-video releases. It's only remembered by the more hardcore fans of the franchise.
* FridgeHorror: A lot of people had this when considering the results of Clifford [[TooMuchInformation marking his territory]]. Thank goodness for the NobodyPoops trope.
* HilariousInHindsight: One episode has Emily Elizabeth recalling that on a PictureDay, her bangs were too short. GreyDeLisle voiced [[spoiler:[[WesternAnimation/AvatarTheLastAirbender another character]] who sliced her own bangs off during her VillainousBreakdown]].
