Thoroughly enjoyable "B" movie, with a solid cast (Kevin Bacon, Fred Ward, Michael Gross, aka the dad from 'Family Ties', and an adorable Reba McEntire).
That first night in Haverhill, MA, the film broke: right as the survivors are riding the bulldozer out of town, a big dark silhouette filled the screen. I thought it was the creature about to attack, but it was the film breaking. We all got free passes for another screening. NOTE: Somehow Tremors has spawned a passel of sequels and a TV show.
