A disease carried by common cockroaches is killing Manhattan children. In an effort to stop the epidemic an entomologist, Susan Tyler, creates a mutant breed of insect that secretes a fluid to kill the roaches. This mutant breed was engineered to die after one generation, but three years later Susan finds out that the species has survived and evolved into a large, gruesome monster that can mimic human form.
Really good watch, will watch again, and do recommend. This is "the movie with bugs that look like people", there aren't a lot of unique ideas out there, so I like celebrating the ones I can point too. While the cast and acting was really good, what makes this is the concept, the atmospheric tension and the practical efforts for the monsters. This is about as close as you can get to being thrown into a termite hive without Rick Moranis or Hank Pym shrinking fools down. Sometimes it is fun to see a pre-apocalyptic story instead of one where the world is already ruined by calamity.
