* The MacGuffin of ''Spy Kids 2'' is highly sought for being able to shut down electrical technology. Apparently, Donnagon has never heard of [=EMP=] bombs.
** The only way to create EMP on a global scale at our current technology is with lots and lots of nukes. Maybe he wanted to take over the world without, y'know, killing all his future subjects with fallout. Also, most military computer systems are EMP hardened, but presumably not MacGuffin hardened.
*** Actually, fallout wouldn't matter. EMP's are generated when nukes are detonated ''very'' high up in the atmosphere. Because the blast would never touch the ground, there would be no fallout.
*** The radiioactive material of the bomb does not simply disappear, and the radiation is enough to irradiate sorounding elements.
*** [[ArtisticLicenseNuclearPhysics Fission products and activation products would remain in the upper atmosphere so long that the overwhelming majority of them will decay into stable nuclides before reaching the surface.]]
** Didn't you watch the movies? Pretty much all the complicated machinery in the series can be replaced by cheaper, conventional methods. For example, five hundred fully sapient robots in the first movie. That sounds really expensive. It's probably be cheaper just to buy a bunch of regular weapons, such as missiles and bombs, and then take the world by brute force. And of course, most conflicts could be resolved very easily if either the good or bad guys ever managed to bring some guns. But hey, it's a kids show, so MST3KMantra.
* Did anyone else notice Mr. Minion's voice changing from extremely high-pitched to normal beetween [=SK1=] and [=SK2=]?
** His voice was originally normal before he was transformed. Perhaps he just needed getting used to his new head to sound normal again.
* How in the world did the parents end up on the same side, working for the same organization? Did one of them defect to the other side? Did they move to a new country, which then welcomed two foreign spies into their own program, blindly trusting that neither were moles for their country of origin? It just doesn't make sense.
*** Because your former workmates would kill you for still knowing the information.
*** It's entirely possible one or both of them could have defected to OSS by giving them important information on their previous employers to become valuable assets, as well as going through some kind of screening process.
* Why was the teleprompter from the second movie legally binding? It's either that, or promotions are handled through verbal contracts, which doesn't make a lick of sense. I realize that ending that scene with "No, wait, this paperwork all says Cortez. Donnagon, explain yourself, or you're fired. Out of a cannon." would have made it impossible to carry out the rest of the movie, but really... All we see is the teleprompter getting hacked, at which point Donnagon takes over.
** On a similar note, if level two ''children'' agents can order around the president, then how come the president chooses their boss? What keeps the president from choosing someone who will lower the power of the OSS?
** Also, how come ''children'' can order around the president?
** Likely, it's a situational thing. Like how the ship's chief medical officer can order the captain in cases of medical concerns. The agents just have highest authority when it comes to protecting the President, but they can't tell him what policies or actions to take in fulfilling his presidential duties.
* Correct me if I'm wrong, but in the third film, when Romero shows up to help in the final battle, he's handed a pair of broken glasses because they're the last ones. Later on though, more characters are handed glasses that are perfectly fine. Why didn't anyone (on the production or otherwise) notice the continuity error?
** Really, he just got broken ones because his normal glasses are broken too and it's funny.
*** Does [[RuleofFunny Rule of Funny]] work if the joke sucked?
*** How so? For one thing, there's FridgeBrilliance in it. Of course they're perfect. Romero is used to wearing broken glasses.
*** Well, if they wanted to make that joke, they could have made Romero the last one to arrive, after all, is not like he did anything that needed to be done before the Giggles kids arrive.
** Maybe they had more glasses, just not on hand, and they wanted everyone to join in the battle as soon as they possibly could, and the only pair they had at the time happened to be broken.
* OK, the OSS suspects Floop is doing... [[EvilPlan something nefarious]], and they're worried about it. So they send a spy in. He never returns. They send another spy in. He also never returns. They send a third spy in. [[RunningGag Yet again, he never returns]]. You'd think by the fourth time they sent in a spy who never returned, they'd realize something ''bad'' was going down and get the Army/Navy/Air Force/[=SEALs=]/A-Team on the horn and storm the damn place.
** Maybe they were involved in a war? Also, the A-Team isn't real in this universe either.
* If playing it backwards is all you need to understand the words of people who were transformed by Floop, then how come nobody noticed that sooner? Was the Internet (specifically Website/YouTube) nonexistent back then or something?
** Yes? The movie came out in 2001, and Website/YouTube was founded in 2005.
*** Even without [=YouTube=], people have been searching for {{backmasking}} since at least the 1970s.
* In the first movie, Machete shows them an airplane that can reach Floop's castle. In the next scene, they stay for the night at his place. Um. Why? Why did he show them the airplane if he wasn't planning to let them use it?
** Subconsciously, Machete knew Carmen was right; if something happened to Gregorio, he would never forgive himself for abandoning his little brother. They are family, and as Carmen points out when he tucks her in, "Family does mean more to you than money." Also it's a character trait he can't resist showing off his gadgets, even to someone who is begging him for help and he won't fight for them. In the second movie he interrupts the kids' privacy to show off their new tools, so it's partly showing off, partly subconscious guilt.
* What happened to Carmen's left arm in the third movie?
** Nothing; it was just a part of the suit she wore while in the game.
* Is anyone else bothered by how quickly everyone forgets about Demetria in the third film? Juni finds out she's the Deceiver and seems really broken up about it, and then she offers to hold the door open, giving the others time to escape, but then once she disappears from the film, Juni goes right into complimenting how awesome his grandpa was and she's never mentioned again, not even after the Toymaker is released from the game and reforms - you'd think he would've...created another one of her, wouldn't he?
** To be fair, after she's gone there's only a few minutes left before the credits.
