I don't think that there is one greatest show ever. It all just depends on what you like or don't like. But the most important factor is premise(sp?). If the show has a good one, then it's acceptable but if it has a dumb one (princes of malibu, the oc, simple life, who wants to be a hilton, the view. etc.) then it just sucks. Also, it's good that a show does what it is supposed to., but makes it apparent.
