This slick throwback to the giant-mutant-insect movies of the 1950's has built a small reputation solely on its irrelevant title -- the film contains no monkeys, blue or otherwise -- which confused both reviewers and viewers alike. (This dilemma was solved in its second video incarnation, under the more honest title Insect.) The story begins when a gardener becomes infected with a plant-borne insect larva, which he disgorges upon his arrival at the County Memorial Hospital. When the bug-baby ingests a large dose of growth hormone called NAC-5 (hospitals are always leaving that stuff around where bugs can get at it), it immediately bulks up to the size of a bulldozer. The plot quickly shifts into Alien mode, as scientists, police (namely wild-eyed cop Steve Railsback) and hospital personnel creep down the hospital's labyrinthine corridors in search of the insectoid monster, which they hope to destroy with conveniently-provided experimental laser equipment before it can test the capacity of the maternity ward with a few million larvae. Despite the lurid promotional materials (showing pretty nurses SCREAMING IN HORROR!!), the story is played quite straight -- more of an homage to films like Them! than a parody of same -- and benefits from good performances (John Vernon is great as the hospital director), a tight script and a strong emphasis on suspense and action from director William Fruet.
