These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
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
Mondegreen: This troper cannot be the only one who misheard Zenon's Catch Phrase "Zetus Lupetis" incorrectly the first time around.
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.
