* BigLippedAlligatorMoment: The musical number that the four-armed alien rocks out into while in the little girls room.
** Even more bizarre, considering he said he doesn't know what music is.
* FridgeHorror: [[spoiler: Only the aliens commander was killed, while the other two escaped. I don't think Sparks is going to get too warm a reception when he returns home.]]
** Actually, it's implied that [[spoiler: they just stayed on Earth. For all they know, they'll be blamed for the invasion failing.]]
* MST3KMantra: You have to be a little patient with the fact that the invasion force is four aliens armed with a single mind control gun that doesn't work on kids.
** They weren't the invasion force, they were only sent there to find the weapon.
* SoOkayItsAverage: The general opinion of the film.
