* AdaptationDisplacement: Loosely adapted from [[http://en.wikipedia.org/wiki/Zenon:_Girl_of_the_21st_Century a 1996 children's book]]. The success of the film did inspire three more Zenon books to be written though.
* FanDiscontinuity: Most fans tend to ignore Z3, due to it being so different from the other two (among other things).
* HilariousInHindsight: Zap Pad in the first movie, this movie was made long before iPads and other subsequent computer tablets became a thing
* {{Mondegreen}}: This troper cannot be the only one who misheard Zenon's CatchPhrase "Zetus Lu''petis''" incorrectly the first time around.
* PeripheryDemographic: ''Zenon'' was targeted at tween girls. Its actual fanbase is all over the map, and doesn't just include those people who were tween girls when they saw it; it also includes geeky types who are in it for the NarmCharm, a few people who think it's a legitimately good movie, and of course the older male fanbase that we don't like to talk about.
* SoBadItsGood: It's a TotallyRadical Disney tween flick that was faaaaar into {{Zeerust}} even when it was made, the music is pure tweenypop written in FutureSlang, and even elementary schoolers know that you use metric in science class. But the movies [[NarmCharm play everything so completely straight, without even a hint of parody]], that your brain can just disengage and enjoy it.
* SpecialEffectsFailure: Then again it is an early 2000's MadeForTV film.
