Sometimes good series not only go bad, they do so at the worst of all possible times — as in, right when they’re coming to an end. As a result, instead of leaving us reflecting fondly on a show that we’ve loved and lost, we’re stuck with an unpleasant aftertaste and a nagging question: It wasn’t always this crummy, was it?

We’ve compiled a list of the 18 worst series finales of all time. Among them are even a couple of show-stoppers that were so atrocious, they were tossed out when the hit comedies in question were revived years later.

Think you know which series finale tops our list as the worst of the worst? Review our picks below, and then hit the comments. (Was any final episode even lousier than the ones that we included?)
