Locusts: The 8th Plague/YMMV
- Anvilicious: The movie really pounds it in that "you shouldn't mess with nature" and "artificial pesticides are evil (but organic ones aren't!)" Even the precautions taken by the scientists (the locusts are supposed to be sterile) don't work.
- Special Effects Failure: You can tell that the victims aren't really being covered in locusts. And while the cows get eaten to the bones, the human corpses aren't (though that might be to make the dead characters recognizable.)
