The townspeople of Eureka are back. In case you’ve missed the first three seasons of this sci-fi (and Syfy) show, Eureka features the adventures, inventions and mishaps of a city of geniuses in Oregon. Renegade robots, spontaneous combustion, and now time travel are all in a day’s work for Sheriff Jack Carter and Dr. Allison Blake, director of Eureka’s main techno-industrial complex, Global Dynamics. Playing as a sort of X-Files-lite (definitely not a slight, simply a reflection on the fact that it’s not nearly as dark or serious as most of the X-Files series), Eureka is actually a pretty fun show, with a solid cast and some enjoyable plotlines.
