Disastrous TV Episodes That Nearly Ruined The Whole Series

Television is far from a perfect medium. Shows that have the potential to run for years get canceled after a single season, while stories that should only take a few hours to tell get stretched into 20+ episode seasons. Bad episodes are inevitable; they're also pretty easy to get past, for the most part. Even the most celebrated shows can miss the mark once or twice, but sometimes an episode is so bad, it puts the entire series at risk of being canceled. From a soap opera worthy plot line to one of the most dramatic haircuts ever, these are the most disastrous TV episodes that nearly ruined the whole series.
