Tubegazing: Eureka

Eureka (Sci-Fi Channel, premières July 18 at 9 p.m. EDT): Farm animals with disappearing body parts, an RV that loses its master bedroom in a flash of sound and light – these are just two of the anomalies a US marshal encounters as he passes through the anything-but-normal Pacific Northwest town of Eureka. Nothing is what it seems – not even his own future – after he replaces the town sheriff, who nearly gets devoured by a hole in the ground. Seems the government has been quietly stockpiling some of the world's brightest – and battiest – men and women in Eureka for years. Good guys and bad guys hope to use the fruit of their "research." You decide which is which. Grade: B
