This would be the show in the shared Warehouse 13 universe that Sci-Fi made when it was still making stellar original programming that could appeal to the entire family. And, like Warehouse 13, it walks that line between adult and child perfectly and in the processes creates a show that everyone in the family will be entertained by despite their age. However, unlike Warehouse 13, Eureka is heavy Science Fiction. It takes a scientific dream community ala Project Y and Los Alamos, only focuses it on a community just as top secret but less ominous, less military, and more family and community orientated than the town that gave us the Fat Man and Little Boy. And, then it takes all that science, and throws it into the hands of the everyman sheriff to clean up after the experiments go wrong. So it is sort of formulaic, but it is formula with an over-arching seasonal plot, and an overarching series plot that makes it a little more in-depth than the monster of the week fair. And, at it's heart, it is just a fun show that is made to entertain. And that is what it does.
