'Bats' (1999) – Louis Morneau.

A young courting couple are graphically slaughtered by a multitude of super-fugly, grotesquely-oversized, uncommonly ferocious bats. Not long thereafter, said red-eyed beasties grimly turn their radar-heightened sights upon the unsuspecting inhabitants of Gallup, Texas. Panic ensues once sheriff Emmett Kimsey (Lou Diamond Phillips) and noted zoologist Sheila Casper (Dina Meyer) disturbingly discover that these genetically mutated bats are extremely deadly, highly sophisticated predators, and not one of them is a vegetarian! All the expectedly lively ingredients are present for a righteous creature feature, prototypical meddling scientist (Bob Gunton), goodly, straight-shooting Sheriff, plucky, whip-smart heroine, amiable comedy sidekick (Leon) and some truly gnarly-looking bats (KNB FX!) Louis Morneau has excitingly produced a slick, nasty-edged creature feature that benefits greatly from its talented cast, mythic western setting and the absolutely eye-poppingly brilliant special FX work of the maestros at KNB! On a personal note, I feel that this unjustly low balled, fabulously bloody 90s Sci-shocker is long overdue some Radar love, man! and Lou Diamond Phillip's solid contribution to genre cinema is no less neglected than his enjoyably Batso B-flick.
