* DesignatedHero: Dr. Ed Wainwright, Creator/PeterGraves' character. He CREATES the monsters, but never, at any point, apologizes for it - even though he's ''directly responsible'' at the very ''least'' for the death of his deaf/mute assistant. He acknowledges it, but treats it as if he simply forgot to feed the dog. Yeah, he does spend the remainder of the film trying to stop what he created, but it's too late. Lampshaded in the ''Series/MysteryScienceTheater3000'' episode.
--> '''Wainwright:''' "In a way, I feel responsible..."
--> '''Mike:''' "'In a way'?!"
* FollowTheLeader: Clearly inspired by ''Film/{{Them}}'', '''the''' big-bug film of TheFifties.
* HilariousInHindsight: [[Film/TransformersDarkOftheMoon Chicago is the scene of a confrontation between the army and huge monsters.]]
* NightmareRetardant: Unlike ants or spiders or most other bugs, grasshoppers really ''don't'' have much visceral horror to them.
* SoOkayItsAverage: An inferior imitation of ''Film/{{Them}}'', to be sure, but it's better than most ''[=MST3K=]'' movies and is even enjoyable in its own right.
* SpecialEffectFailure
** The giant grasshoppers crawling up the buildings are clearly actually just regular sized grasshoppers crawling across a postcard.
** Every time someone drives down that Certain Stretch Of Road (the dead giveaway would be those same two cars that are perpetually going the opposite direction).
