Mimic. When a virus carried by cockroaches begins killing kids en masse in Washington, a scientist (Mira Sorvino) genetically engineers a new insect that is lethal to cockroaches. The operation is a success, but three years later she discovers evidence that the bugs, which were supposed have a limited lifespan, are not only still alive but evolving at a rapid pace into something large and terrifying... Always enjoyed this late 90s big bug horror flick and still do, it's cool, stylish and scary and looks great on Blu-ray.
