* AlternateCharacterInterpretation: With its agents constantly going rogue, and its use of children for dangerous missions, it's not hard to argue that the OSS are corrupt and villainous.
* SugarWiki/AwesomeMusic: "Isle of Dreams", the song played during the end credits of the second movie.
** The third movie is also filled with this.
* BigLippedAlligatorMoment: The appearance of the "real Guy" (played by Elijah Wood) in the third movie. To clarify, he just suddenly shows up, gives an inspirational speech... then he gets severely curb-stomped, booting him out of the game. He is never talked about again.
** Both the first and second film end with a post-credits scene, the first being a shot of inside Floop's castle and the second of the treehouse. Nothing happens in either sequence.
* ContestedSequel: The second film.
* CriticalDissonance: The first and second films have 93% and 74% on Rotten Tomatoes, respectively, but audience scores of 45% and 38%. Also, on Website/IMDb, the average ratings for the films are are 5.4 and 5.1.
* DracoInLeatherPants: Gary Giggles. Invoked in-film by Carmen.
* EarWorm: "[[https://www.youtube.com/watch?v=AMphtvvSo5w Floop's Song]]". Doesn't really help that this song was written by Danny Elfman.
* FirstInstallmentWins: The first movie was the best received.
* FridgeHorror: So if Minion was going to replace all the world officials' kids with robots, what was he going to do with the originals?
* FridgeLogic: The children of the most important people in the world are all apparently the exact same age...
* HamAndCheese: ''Creator/SylvesterStallone'' as The Toymaker in the third movie. He is clearly having the time of his life as a madman evil video game programmer who talks to holograms of himself as a hippie, a general and a mad scientist. Him sporadically shouting his dialogue helps.

* HilariousInHindsight:
** The first scene of the first movie is Alexa Vega in a white nightgown, staring out the window. [[Film/RepoTheGeneticOpera The same sort of scene that happens several years later.]]
** Also, in ''Game Over'', Juni being referred to, within a video game, as "[[VideoGame/IWannaBeTheGuy the Guy]]".
*** And when the real "Guy" ''does'' show up, he [[NintendoHard dies]] [[EverythingTryingToKillYou almost]] [[FakeDifficulty instantly]]. Sounds about right.
** At the beginning, Juni has warts on his hands. Later on, the same actor stars in ''WorldsGreatestDad'', as a [[ADateWithRosiePalms frequent masturbator]]. You know what they say...
** In ''3D: Game Over'', Juni at one point is controlling [[Film/{{Transformers}} a giant yellow robot.]]
** The second movie has a watch that can do virtually everything ''but'' tell time. [[http://www.tomsguide.com/us/apple-watch-faq,news-19966.html Seems like Apple took this concept seriously.]]
* IdiotPlot: ''Spy Kids 2'' has a plot that is largely driven by every character being stupid.
** The president announces the new head of the OSS during his speech at the party. The screen he reads off of starts saying, "Gregorio Cortez", but then changes to "Donnagon Giggles". They way it happens makes it blatantly clear that his teleprompter was hacked, not experiencing a typo or malfunction, yet he never questions it. For that matter, the president is clearly about to say, "Gregorio Cortez" before his screen changes, yet no one at the party is suspicious of the obvious sabotage going on. Also, the president's announcement alone probably shouldn't be the deciding factor for who becomes head of the OSS, and the decision was probably already made before his announcement at the party. Shouldn't someone be investigating why his speech was changed instead of automatically instating Donnagon as the head?
** When Donnagon is making is speech, he promotes Gary and Gerti to level one agents. Is no one going to call him out on the blatant {{Nepotism}}?
** At the party, all of the wine glasses have been drugged, and all the adults are rendered unconscious when they all have a toast. Apparently, the villains never considered that someone might drink from their glass before the big toast, which would've exposed them if it happened. The fact that one of the waiters tries to give a wine glass to Juni implies that they expected everyone to be knocked out, including the kids. Seems they DidntThinkThisThrough.
** The Magnamen were able to steal the Transmooker device from the president after all the adults were drugged. If it's such a highly dangerous device that was on his desk initially, why did he just have it in his jacket pocket? The last time the device was seen, it was being carried away by helicopter, so you'd expect them to put it somewhere more secure, especially since it just got stolen.
** Juni gets fired from the OSS entirely because Gary Giggles accused him. Did no one seriously consider getting Juni's testimony on those events? Or the testimony of the other spy kids who were there?
*** For that matter, no one seriously questions how Juni got reinstated so quickly.
** Carmen and Juni are able to learn about the Ukata assignment by having R.A.L.P.H. spy on Gary and Gerti as their father is briefing them on the mission. The reason R.A.L.P.H. was able to spy on them was because Juni apparently left it on his desk, which he knew was going to be cleaned out. You'd think he'd take a valuable piece of technology (and companion) with him when he left.
** Felix gives Carmen and Juni the Ukata assignment, which he should know is a level one agent mission. Why does he not question why level two agents are getting this mission?
** The Giggles siblings are put on a vessel to the Gobi Desert. Apparently, they relied solely on autopilot and never noticed that they were going somewhere far away from the location that their father told them to go to.
** By the time they actually reach the island, you would think Carmen would've figured out by that point that electronic technology doesn't operate in that area, based on her experiences in the [=DragonSpy=] vessel and the amount of time she's had to think about it. Yet she still expects her spy gadgetry to make an automatic campsite on the beach.
** Romero's growth serum falling into his "Romero's Zoo Two" is the reason for why the island is full of gigantic MixAndMatchCritters. The flashback depicting this event shows a stunning lack of caution in his initial use of the serum.
** [[ArsonMurderAndJaywalking Someone should fire the architect who designed the office of the head of the OSS]]. There is [[NoOSHACompliance no way that room is safe at all]]. For one, there is no floor. There's just a regular desk on an elevated platform with very little walking room, and the only way to get across the deep abyss it stands in the middle of is to walk on very small floating platforms that fly over to beneath your foot just before you would take a step and fall to your death.
* JustHereForGodzilla: Oh be honest, the only reason any of us saw ''All The Time In The World'' is for Juni and Carmen's parts.
* MemeticMutation:
** FLOOP IS A MADMAN HELP US SAVE US!
** "Do you think God stays in Heaven because he too lives in fear of what he's created?"
** SOMEBODY ING THE DINKSTER?
* NightmareFuel:
** The Fooglies [[spoiler: and what they really are]].
** Don't forget their song. ''Floop is a madman, help us, save us, Floop is a madman, help us, save us!''
** And this happens to [[spoiler:their dad!]]
* {{Padding}}: Juni's relationship with Alexandra in the second film, who's daddy issues are barely explained and who doesn't reappear for the third film; Demetra herself isn't much better, and is forgotten about entirely after her HeroicSacrifice.
** Elijah Wood's cameo as "The Guy", who lasts for all of sixty seconds upon his reveal.
* {{Sequelitis}}:
** The second film and the third one.
** [[FranchiseZombie And here comes a fourth....]]
* SoBadItsGood: The third film, often considered the best one for being the most hilarious.
* SpecialEffectsFailure: The 3D in the third movie is very poorly done, barely resembling 3D at all. Understandable, seeing as this movie came out when the advent of 3D was still trying to get on its feet, and the movie itself was filmed using a primitive version of Creator/JamesCameron's 3D camera system.
** The greenscreening is also incredibly blatant, especially during the fight scene at the end of the movie.
** One from early in the first movie involves Ingrid moving her chair over to Gregorio. The track on which her chair is on is very clearly visible. Whether this is justifiable as yet another spy gadget's visible elements is debatable.
* {{Squick}}: At one point in the second movie, Gerti and Gary wind up in a desert (due to Carmen and Juni's medaling) and are unsure of where they are. They fall into what at first seems to be a mud pit, only to look around and see camels surrounding them. Horrified, Gerti exclaims that it is, indeed, [[spoiler:camel poop]]. Skip a few seconds into the future, and you see Gary opening his mouth and spitting a big chunk of...er, "mud" out of his teeth.
** The fourth film sees Jessica Alba use her baby's used diapers as weapons against several mooks in the movie.
* TearJerker: Gregario imagining himself trouncing a bully's parent (which he easily could) and impressing Juni. All he wants is to be his son's hero.
** The Timekeeper's backstory in the fourth movie. Frozen in time, forced to watch his father grow old, wasting his life trying to find a way to free him, only to be released by a DeusExMachina ''after'' his death. Say what you will about the rest of the film, that is heartbreaking.
* TheyJustDidntCare: The fourth film has a [[ContinuityPorn special Spy Kids room full of different props and paraphernalia from the Kids division]]...much of which was not directly related to the division at all, such as equipment from the Third Brain experiment, and the battle suits from Game Over. ''Which didn't physically exist.''
* TheyWastedAPerfectlyGoodPlot: The third film might have been a little better if it had put more focus on Grandpa getting to ''feel'' young and powerful again, instead of summing his CharacterDevelopment up in a little speech at the end.
* ToyShip: Juni and Alexandra in the second film, and Juni and Demetra in the third film (with a ShipTease of Juni and Gertie at the end, too). Carmen, who at least looked old enough to be interested in the opposite sex, only got an unreciprocated crush on Gary in the second film.
* WTHCostumingDepartment: Some of the battle suits from the third movie are quite laughable. "The Guy" in particular looks absolutely hysterical for a supposed badass.
