Eureka is a lighthearted sci-fi show on the Syfy channel. I confess: I had not seen it prior to the blogging challenge but I needed an "E" show that fit with my taste and qualifications (sorry, no Everybody Loves Raymond!) . The first three seasons are conveniently available on Netflix streaming.
Eureka takes place in the quirky fictional town of Eureka, Oregon, the headquarters of research facility Global Dynamics (think Fringe's Massive Dynamic but more wacky than creepy). A U.S. Marshal happens upon the town with his teen daughter (appropriately angsty wearing a choker and a nose ring). They end up sticking around to solve various oddities, mostly fallout from Global Dynamic's experiments, with the help of the Eureka's scientist and inventor townsfolk.
Factoid: After a little poking around, I found seasons two and three were composed by Bear McCreary of Battlestar Galactica fame. Yes, I watch enough TV to recognize composer names. Who can forget a guy named Bear?
