In the history of television, countless great shows have suffered from a bad conclusion. Some final scenes feel rushed, while others have poor writing and character choices. In many instances, shows are forced to end when they aren't renewed for another season, which also leads to unfinished plots and unanswered questions.

When this happens, a once-loved series can easily fall from grace and lose its place among the best in television.

No matter the circumstances, they all lead to unsatisfied fans and unfulfilling stories.

Criminal Minds met great success, but some fans viewed the series finale as a lackluster sendoff. At the end of the series, the BAU team has a final conversation and says goodbye to one another. The scene is sweet and fun to watch, but its mundanity makes it seem like a season finale, rather than the end of the entire series. Hopefully, the upcoming revival, Criminal Minds: Evolution, won't suffer the same fate.
