Looking for entertaining summer television that's not on HBO? You should start watching Eureka! Tonight's the third episode of the new season (its fourth). This write up is pretty good, but doesn't quite do it justice. I always get excited when I see this one on my DVR; it's got great characters and an interesting conceit (a town populated entirely by geniuses developing new technology, and the non-genius sheriff who saves the day when their mad cap experiments go awry). I've got the first season on DVD (available for borrowing), and 2 and 3 seem to be on Hulu. It's light without being dumb, and makes for great summer tv worth watching.
