We all get excited when our favorite shows get renewed for another season. But, sometimes those renewals end up being disappointments, and the shows last well past their prime. While some fans will stick with it to the end, ratings typically drop, and the shows either end bitterly or drag on even longer, ruining the memory some hold for them. So, I rounded up ten shows that should’ve avoided that fate.


Supernatural Season 7 Sam, Dean Winchester Brothers
Warner Bros. Television Distribution | Kripke Enterprises | Wonderland Sound and Vision

Supernatural was supposed to end after five seasons, so who made a deal with a crossroads demon for ten more? This show could’ve ended nicely in so many places, but they kept going for 15 seasons. Each season kept getting darker, and we lost that charm that had us hooked in the first half. Seriously, the last four seasons shouldn’t have happened.

If we had to get more than five seasons, season seven would have been the perfect spot. They just defeated the Leviathans, which were the best monsters of the series. Dean gets thrown into Purgatory and stays there, Castiel doesn’t come back to life, and Sam gets the “normal” life he’s always wanted. We wouldn’t have had to deal with the creators trying and failing to make better monsters.


NCIS Gibbs, Mark Harmon

NCIS has been on the air for 19 seasons. It still hasn’t been canceled or renewed for season 20, but I’m hoping this is the last of this show. It’s been a long time coming, and I can’t believe I’ve been keeping up with it for so many years. Even Mark Harmon thinks it’s gone on too long (he left this season, in case you didn’t know).

Honestly, it should’ve ended after Ziva left in season 11 or when Tony left in season 13, but since I like Ellie and Nick so much, I’m letting it slide. The last straw was when Abby left. She was the only reason I started watching, and when she left, I lost most of my interest. Seriously, I have no idea why I’m still watching the series.

‘Grey’s Anatomy’

Why is this still on the air? Shonda Rhimes left after season 13, so why didn’t they just end it there? My friends that still watch Grey’s Anatomy are only watching for one or two characters. They said the show is boring, and they’re finding it harder to binge-watch nowadays.

Hopefully, the show is on its last season. I know some people will disagree with that, but there are plenty of other medical dramas out there that have better storylines and characters. Not to mention, there’s Station 19, the spinoff following Seattle’s fire station.


Riverdale Archie, Veronica, Jughead, Betty
Warner Bros. Television Distribution | Berlanti Productions | Archie Comics | CBS Studios

Riverdale should have ended after season one. Everybody knows it, even the cast. Some have even said they don’t understand what’s even going on in the show anymore. And that’s only the plot; we aren’t even talking about the horrible dialogue.

Season one would have been a nice ending to an outstanding miniseries, but the show was too popular to not keep it going. That was their first mistake. And I’ll only forgive one episode post-season one, and that’s the season four premiere where they honored Luke Perry.

‘Family Guy’

There are so many cartoons that are still on the air that should have been canceled years ago. Family Guy is one of them. Creator Seth McFarlane even said as much, adding that seven seasons is perfect for most shows. Sadly, the show has been running twelve seasons past that.

Family Guy should have ended long ago. What else could they think of to put this family through? The same could be said for The Simpsons, but since they keep predicting random events in history, I kind of want to see what they’ll come up with next.

‘The Vampire Diaries’

Don’t get me wrong, I love The Vampire Diaries, both books and all three television series. That said, the last two seasons of The Vampire Diaries weren’t good. The only redeeming factors were Josie and Lizzie being born, Katherine coming back for one last laugh, and Stefan being redeemed in my eyes.

Now, I could’ve dealt with season seven on its own for one specific reason. It directly correlates to Legacies, which is actually turning out to be a good show. However, season eight was out of left field when it should’ve been left there.

‘Once Upon a Time’

Once Upon a Time Season 7 Henry, Emma, Killian
Disney-ABC Domestic Television | ABC Studios | Kitsis/Horowitz

I had so much hope for this show when it was announced, but I was let down. I haven’t even gotten through season two yet, but my parents watched the entire series. Season seven was unnecessary with the time jump and half of the original cast missing.

That said, I think it should have ended after the first season when Emma broke the spell. But, since I’ve heard Killian Jones and Emma Swan’s relationship is amazing, ending after season six would have been perfect for hardcore fans of the show.

‘Pretty Little Liars’

Coming from someone who read the books and watched most of the show, season two would have been the best way to end Pretty Little Liars. Even season four would have been better than what we got from the series finale. I hated that more than the final season of Game of Thrones.

Hopefully, this new spinoff in the works will finally get it right. Or, better yet, we get a good adaptation of Sara Shepard’s other mystery series, The Lying Game. We could get so many better things than a surprise twin that was never hinted at in the show.

‘The 100’

The 100 may be one of my favorite shows, but I admit the last season was horrible. I will never forgive the writers for what they did to Bellamy and Madi. I also couldn’t stand Hope, but I think that’s just because she seemed like an Octavia wannabe and not an original character.

The show ending after season four would have been perfect. That said, ending after season six would have given the characters the happy ending they deserved. We could have been spared the heartbreaking deaths and weird time plot that didn’t make sense.

‘Spongebob Squarepants’

Don’t hate me, but Spongebob should have ended after four or five seasons. Technically it’s only been on for 13 (going on 14) seasons, but it feels like it’s been on for 90. And I could probably tell you the plot of maybe 10 episodes. And one of those is the iconic marching band episode.

The quality of the show, specifically the writing, plot, and dialogue, went downhill around season four. And since the show doesn’t have consistent story arcs from season to season, it’s hard to pinpoint if it should have ended then or when creator Stephen Hillenburg died in 2018.
