Most of the TV I watch either has to do with the occult or have some sort of deeper meaning. Its so hard to find a popular show that has clever writers on staff.
The best is, of course, crime dramas, such as CSI or the Law and Order series. Comedies of this callibur include Golden Girls and (surprisingly enough) Friends.
With a very limited numbner of good movies out right now, it is refreshing to know that not all summer reruns are mindless dribble.
