The paint-by-numbers plot of "Slugs" is hardly innovative, even for a horror movie: chemical wastes generate mutated, flesh-eating killer slugs in a small community whose authority figures refuse to believe the stalwart head of the local health department until it is too late. Our heroes are on their own to devise a way to kill the beasties and do so with explosive vigor and sacrifice...except. And although the film was made after Roger Corman left New World, it has his trademark drive-in blend of teen sex, blood, and gross-out makeup effects.
But the direction is tight, efficient and never lagging, with good production values within its budget and mostly competent acting and dialog that lets the clichés roll. Special effects are quite well done (if generally repulsive), and the small town atmosphere (exteriors were primarily filmed in the upstate New York town of Lyons) is effective.
Slugs is an above average entry into the low budget eco-horror genre, good for those who still miss Saturday night at the drive-in.
