Big-Lipped Alligator Moment: About two thirds through the film, the survivors stumble upon a battle between the black ants that have been harassing them and a second group of giant red ants. The red ants are never seen or mentioned again and don't even appear during the climax when all the black ants are killed.
Narm: Plenty to be found. Notably in the extremely hammy opening narration about ant behavior and Pheromones.
Special Effects Failure: While the giant puppets the characters occasional interact with are fairly effective, most of the effects shots are accomplished by poorly superimposing stock footage and having the actors react.
