Kevin Bacon is clearly having some good fun in this daft family sci-fi story. He and his pal "Earl" (Fred Bass) make a living doing odd (and unsavoury) jobs around their small community until they discover that something - subterranean - is lurking and it's hungry. What ensues now are a series of entertaining escapades as the two, with newly arrived seismologist "Rhonda" (Finn Carter) and the townsfolk try to stay one step ahead of their voracious pursuers. It's a bit of a slow burn at the start, but once we get down to the nitty gritty, Ron Underwood keeps the action flowing well with a lively script and some personable efforts from all concerned. It's enjoyable, this film, with some engaging performances - especially the "Gummer" pairing of Michael Gross and Reba McEntire who have enough weaponry to start and win WWIII - and it doesn't rely overly on complicated visual effects. On that front it is more reminiscent of a Hammer film! Everyone looks like they enjoyed making this, and that's contagious, so sit back and watch it bring a smile to your face.
