This film stays in the vein of campy, but brilliant action flick much like Tremors 3. It's humorous, scary, and always exciting.
Building on the success of Michael Gross as Burt Gummer, we have Gross as the ancestor of Burt, Hiram Gummer. Hiram is a wealthy owner of the local mine. He is snotty, cowardly, and can't shoot a gun to save his life. The townspeople really don't care for him and his greedy ways.
He arrives just as the mine is being abandoned. 17 miners have disappeared in the caves and everyone is scared to enter. The local Indian claims it to be spirits haunting the caves. Hiram needs the silver in the mine to remain wealthy and gathers a ragtag group of desperate miners to check it out. A brief attack by "dirt dragons" and Hiram is ready to abandon the town of Rejection and his mine. The few remaining townspeople are desperate for a solution.
If you enjoy the Tremors franchise you will love this new installment. The special effects are awesome, using giant "puppets" instead of cgi adding a real quality to the attacks. The origins of the graboids are somewhat revealed and the town of Perfection is born. There are many references to the first Tremors and fans will appreciate the thought put into the film. I truly enjoyed this Graboid attack. 7/10.
