10 TV Shows That Shot Themselves In The Foot

10. Over-Extending When It Should Have Ended - Supernatural

Given Supernatural's uber-successful 15-season run, it'd be understandable if you scoffed at its placement on its list because, in all honesty, it's clearly doing something right. That much is certainly true as the show has stood the test of time and will bow out with the conclusion of its fifteenth season, but this isn't the first time it's been faced with a potential conclusion and it was The CW's money-driven decision to revive it that has prevented it from delivering the definitive ending it truly deserved.

The truth is that Supernatural was originally envisioned as a five-season show by creator Eric Kripke. The show was supposed to chart the adventures of Sam and Dean Winchester as they learned more about their family history and how the demons they were hunting would lead them to their destination. And that's exactly how it all panned out, with the fifth season bringing that overarching story to an emphatic end.

However, due to its overwhelming popularity, The CW went ahead and renewed it for a sixth anyway - in spite of Kripke's desires to end it on his terms. And with that, it devolved into a directionless shell of what it once was, bogged down with fillers while having little to no idea what its new endgame was.

Supernatural had the chance to be an open-and-closed book when it came to telling a well-crafted story, but its popularity kept it on life-support long after it truly ended, and thus, two thirds of its groundbreaking run have been completely unnecessary offerings that couldn't dream of reaching the heights of the first five seasons - and that's a darn shame.
