Tremors didn't actually break any new ground (even though its tunneling worm monsters certainly did), but it revved up the classic monster-movie formulas of the 1950s with such energetic enthusiasm and humor that it made everything old seem new again. It's also got a cast full of enjoyable actors who clearly had a lot of fun making the film, and director Ron Underwood strikes just the right balance of comedy and terror as a band of small-town rednecks battles a lot of really nasty-looking giant worms. The special effects are great, the one-liners fly fast and furious between heroes Kevin Bacon and Fred Ward (and yes, that's country star Reba McEntire packin' awesome firepower), and it's all done with the kind of flair one rarely associates with goofy monster flicks like this. --Jeff Shannon
