5. 'Criminal Minds'
While the first 13 seasons of Criminal Minds received an average of 23 episodes per season, Season 14 garnered a mere 15-episode order. The long-running CBS drama will soon reach its 300th episode. All of that means nothing if ratings are down. Season 14 debuted to 4.45 million viewers, easily making it the lowest watched episode of the entire series. After suffering the loss of major characters like Aaron Hotchner and Derek Morgan, perhaps it's time to write the final chapter for Criminal Minds.
