Mimic
1997
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.

My notes
Chronologically, this might have been my first del Toro film. It's competently directed with creature effects as good as to be expected. The one thing I really disliked about this one is that people aren't 'wrong'. Every hypothesis that a person makes turns out to be true. This took a lot of the tension out of the film for me.
