* FanonDiscontinuity: The original may not be anything special, but even its fans wish that the sequel never came to be.
* FreudWasRight: Some people think Kilowatt's head resembles a breast.
* FridgeHorror: They need a nose cone for their spaceship for re-entry. [[spoiler:So they use the frozen, but still blinking, Zartog.]]
* HilariousInHindsight: Malgor is an alien world with technicolor flora and fauna, a MacGuffin material and predominantly blue aliens with flying mounts resembling stingrays at their disposal. [[{{Film/Avatar}} Yeah.]]
* OlderThanTheyThink: The Nineties cartoon ''WesternAnimation/CaptainSimianAndTheSpaceMonkeys'' was pretty much exactly the same thing.
* {{Sequelitis}}
* SpecialEffectsFailure: The CGI in the first movie isn't honestly "bad" [[SoOkayItsAverage per se]], but there's a noticeably MinimalistCast when it comes to the humans and the design of Zartog's race ''is'' pretty bland. But to put things in perspective: the film came out in 2008, 1 month after ''[[WesternAnimation/WallE WALL•E]]'' did, ''and just compare those two''[[note]]it's also worth pointing out that ''WALL•E'' had a much higher budget than this film ($180,000,000 as opposed to $40,000,000)[[/note]].
** The second movie, given its [[DirectToVideo straight to DVD]] status, plays this a little more straighter. It is also something of an OldShame to [[Creator/PranaStudios the animation company]] behind that film. Up to, and including, not mentioning it on their own website.
