This is a surprisingly entertaining made-for-video sequel to Ron Underwood's minor classic monster movie. The giant worms are munching in Mexico, so Fred Ward is called in as bounty hunter, along with enthusiastic assistant Christopher Gartin. Sharply written and engagingly performed, this benefits from staying true to the jokey spirit of the first film, while adding a new breed of overground "graboids" to literally chew the scenery. Although it lacks the frantic pace and sprightly camerawork of the original, it's smarter and more fun than many cinema follow-ups and Michael Gross is once again hilarious as fearless gun-nut Burt.

Earl Bassett's celebrity after defeating the Graboid attack against the town of Perfection has proved short-lived, until he's recruited by a Mexican oil company whose workers have found more than they bargained for under the soil.
