I watched Eureka for the first time last night, and I'm not clear what the premise of the show is, exactly. Everyone in Eureka is super-smart except for the Sheriff and his daughter? There is super-technology wandering around all over the place. Did they steal it from the future, or invent it, or what? Are they in the far future, and Sheriff is Buck Rogers? Are they the only advanced town, or is the whole world like this? Why doesn't the sheriff fit in? And there's some sort of underlying mystery going on (somebody didn't die of natural causes)? Thanks to anyone who can get me up to speed.
