* BigLippedAlligatorMoment:
** The portraits with the moving eyes at the beginning? Never explained, beyond a vague implication that Manzini is fond of collecting magical items.
** The reference of the Garbage Pail Kids being aliens through the implications of the trash spaceship.
** The part where the Kids [[ThatRemindsMeOfASong break out in song]], since there are no other musical scenes in the movie, and this music sequence comes out of nowhere in the middle of another scene.
* BileFascination: Given its reputation, probably the only reason most have for checking it out at all.
* DesignatedHero:
** The Garbage Pail Kids are clearly just as much horrible if not worse than Juice and his gang; they terrorize the neighborhood on a daily basis with their unpredictable antics and obnoxious behavior with absolutely NO motivation whatsoever other than [[ForTheEvulz being nasty for the sake of being nasty]]. They don't treat Dodger any better, yet he's trying to make some ''sense'' out of them. They even share the bullies' taste in fashion!
** Captain Manzini is intended to be the BigGood, but the most heroic thing he does is spring the Garbage Pail Kids from prison... so that he can imprison them again inside a trash can.
* FridgeLogic: If they come from ''space'', does it mean there's a ''whole planet'' of those atrocities?!? If so, it's all the reason we need to build a functional [[StarWars Death Star]].
* JerkassWoobie: Tangerine uses Dodger and the GPK to make herself look good as a fashion designer and even ends up betraying them. At the same time though, one could feel sorry for her: it's implied that Juice is abusive as he does rough her up at times.
* NauseaFuel: Given how disgusting the source material was, not surprising.
* NightmareFuel:
** The Garbage Pail Kids themselves. They probably didn't intend on making them so horrific-looking, but they are.
** The whole concept of the State Home For The Ugly.
* {{Padding}}: There are several long, dragging scenes of the Kids interacting. Typically scenes like this would be used for character development or exposition, but in this movie a lot of the dialogue scenes contribute very little to the film's story. Particularly of note is a three-minute sequence of the Kids playing a prank on a random man by [[JerkAss redirecting a sewer pipe into his hot tub]].
* RootingForTheEmpire: As... idiotic as the idea of the State Home for the Ugly is, the fact that they want to apparently outright murder the obnoxious protagonists actually makes some people want to root for them merely for that reason alone.
* RunningGag: The nerd kid pissing his pants. He keeps doing it [[SarcasmMode because it was so funny the 1st time.]]
* SnarkBait: The only reason most people who are well-informed about this movie might want to watch it.
* SpecialEffectsFailure: The ship at the beginning of the film is a model that ''clearly'' looks like a "not-quite finished" model in front of a half-assed painting of Earth.
* {{Squick}}:
** Tangerine and Dodger hitting on each other. She is in her twenties (or, at least, [[DawsonCasting looks so]]) and he is fifteen. Shockingly, Tangerine's actor is only a year older than Dodger's.
** The Kids themselves who fart, piss and threaten people every other minute despite wanting to be acknowledged and one even has a knife. They are just nasty in every sense of the word.
* TookTheBadFilmSeriously: Anthony Newley, who played Captain Manzini, stayed to the end of this movie because he believed in the project. Ironically, [[StarDerailingRole this was his last film.]]
* UncannyValley: The Garbage Pail Kids are little people in horrible, horrible rubber outfits. The suits are so badly designed that their mouths can't even ''close''. Your dreams will be haunted.
* WhatDoYouMeanItsForKids: This film got away with a PG rating and is based on a franchise popular with boys aged 9 and up. However, amongst many, MANY other things we have underage drinking, thuggery, assault, a few curse words, near-nudity and implied genocide, sexual abuse and murder. This actually drew the wrath of parents and got GPK withdrawn from theatres only weeks after its premiere, which resulted in the film becoming one of the bigger box office bombs of 1987 and derailing the franchise as a whole.
