“Tremors” now sits alongside films like “Gremlins” as part of a small group of movies suitable for families that also feature monsters. Kevin Bacon and Fred Ward have a palpable connection as two arguing maintenance workers in Perfection, Nevada, which has a population of just 14 people when it’s attacked by underground creatures called "graboids" – yes, the name is silly, but it somehow works within the film's world. Despite leading to numerous disappointing sequels, “Tremors” remains enjoyable due to its strong cast, well-crafted plot, and impressive special effects achieved through practical means.
