These shows are not the funniest, the smartest, the wittiest or the most interesting. They're there to pass the time, they're light-hearted, easy to follow with only half your attention on the screen, and the laugh-track even lets you know when you might have missed an obvious pun, if you want to go back and smile. Despite everything, we watch them with an involved interest as to what's gonna happen to the characters. Yup, that's sitcoms for you.
