When it comes to television, especially the long running series we grew up with and loyally followed every week, it stands to reason that many categories of classification are born from this. The 'best' episodes, the 'saddest' episodes, the 'scariest' episodes, and so on. But whether we like it or not, whether anyone intended to or not, there's another category that no one typically likes talking about; the one that no series can ever seem to escape from: the 'crap' episode.
