- Adaptation Displacement: Loosely adapted from a 1996 children's book. The success of the film did inspire three more Zenon books to be written though.
- Fan Discontinuity: Most fans tend to ignore Z3, due to it being so different from the other two (among other things).
- Hilarious in Hindsight: Zap Pad in the first movie, this movie was made long before iPads and other subsequent computer tablets became a thing
- Periphery Demographic: 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 Narm Charm, 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.
- So Bad, It's Good: It's a Totally Radical Disney tween flick that was faaaaar into Zeerust even when it was made, the music is pure tweenypop written in Future Slang, and even elementary schoolers know that you use metric in science class. But the movies play everything so completely straight, without even a hint of parody, that your brain can just disengage and enjoy it.
- Special Effects Failure: Though some of the effects are decent for a TV movie from the early 2000s, such as shots of the space station, others, such as Zenon floating out in front of the space station, don't fare nearly as well.
