Burt Gummer returns to be the veteran in the hunt for graboids. We suppose that his wife has not survived, regardless of what has eaten her: a fact that we accept quite nicely. This time, the tension is not as high. The villagers are not too worried about getting eaten after eleven years of ups and downs.
Nevertheless, after a half dozen murders and multiple warnings by the association for the protection against graboids, things become more serious and a war explodes. Tremors 2 showcased graboids who had evolved, in less than five years, from creatures who reacted to vibration to creatures who react to heat. Once again, they also seem to react to heat but have developed an even more unrealistic power. In 2001, they have learned to use their anus to gracefully shoot themselves in the air.
The film itself isnít bad but the element that created the suspense in the original, where heroes avoided touching the ground, is no longer present. Here, these creatures have become so strong and flawless that the movie becomes no more than a low budget Jurassic Park.
