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.
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 MST3K Mantra.
If I remember correctly, the 500 child robots weren't supposed to conquer the world through brute force, they were intended to replace the children of people in power and through that manipulate them into doing what the controller demanded, such as pass legislation that would benefit them and eventually just kill off said people outright and take over in the resulting confusion. Overall a much more realistic and more likely to succeed way of taking over the world than sheer military force.
Did anyone else notice Mr. Minion's voice changing from extremely high-pitched to normal beetween SK1 and SK2?
It probably just wore off.
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.
Maybe one of their countries collapsed and the other became an ally to help them out, à la the collapse of the Soviet Union (or the Klingon Empire in Star Trek VI if you prefer). The collapse could've meant the end of their spy program, so why not join the spy program of your new ally?
Because your former workmates would kill you for still knowing the information.
Did they ever mention what side they were on? They could have left their former organizations to join the OSS.
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.
Well, the President character was pretty clearly established as a moron.
On a similar note, if level two children agents can order around the president, then how come the president choses 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?
If you're talking about what I think you're talking about, it's one of those For Your Own Good things. They don't actually have the authority to make the president do anything, but they can very, very strongly "suggest" it in a way that (due to time constraints and emphasis) doesn't need to be politely phrased as a question. There are things in Real Life at that level where high-ranking government agents that go against the President's wishes in the express completion of their duties might get an automatic pardon if it's required that the President "agree" to do something but the classification of the material required to genuinely convince him is higher than what he is allowed to know and/or higher than what he is allowed to make decisions about.
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.
Alternatively, it could still work out- if his normal glasses are broken, he'd have gotten used to seeing the world like that. While the new glasses aren't likely to be broken in the same place(s), it might still be easier for him to see through something skewed than a near perfect picture.
OK, the OSS suspects Floop is doing... 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. 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.
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 YouTube) nonexistent back then or something?
Yes. The film came out in 2001, and YouTube came out in 2005.
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?
He showed them the plane because they asked if he had anything that they could use. But he didn't say he would actually let them use the plane.
What happened to Carmen's left arm in the third movie?
It's just a robot claw she has in the video game world. In the real world, she still has both her arms.
