“Worst” as defined by you. (It’s a blanket question so how you answer is as interesting to me as the content of the answer.)
I thought Firefly was bad, but for me personally Final Space takes the cake. They really screwed the guy over.
You?
Altered Carbon. Season one was top-notch, season two brought all the nails to shut that coffin.
Has to be Mind Hunter.
I still can’t believe there were only two seasons, this show was outstanding
The Expanse. The last books are my favorite in the series. Still hoping they finish…
I think it was a naturally stopping point. Maybe they can restart it with the same cast in… 20 years?
That is really my hope. The story picks up many years later so once the actors look 5 years older and have some grey hairs then I want them to film the next set of books.
Probably my answer, but it’s a shame Alex (the actor) was an ass and had to get canned. Not that he was my favorite character, but it felt a bit off without him.
Still hoping they finish…
Ditto. I still haven’t read the books, but as I understand it, the biggest “hook” for me in the show is in those last three yet to be adapted.
Terra Nova… Would have loved to have more dinosaurs
To bad they thought people were more intersted in family drama then friggin dinosaurs.
After a recent rewatch, I would have to put forward Better Off Ted as top of my list of worst cancellations. Truly underrated when it ran, the writing was witty and sharp, aligning with the humour of Scrubs and Community.
Speaking of, re-watching Community slowly peter-out over the seasons (despite my excitement for the movie!), does preclude me from putting it at the top of the list.
Lastly, for my wasted potential award, I would say Westworld was cancelled just as it sat on the edge of redemption. Season one was a masterpiece, while season two felt like a big retread. Seasons 3&4 were controversial due to the drastic shift in setting to the real (future) world, however the ending of S4 leading back into the Wild West setting was so promising!
I was onboard with season 3 and was ok with 4 until they did Maeve so damn dirty. After that I said “fuck this show”.
Lastly, for my wasted potential award, I would say Westworld was cancelled just as it sat on the edge of redemption.
I have words on that,
/agree is the short answer. Long answer is too long for this moment. Just, slash agree. It was a planned five seasons and we ended on a low point four season in because we dirty fuckin’ humans deserve to end on a low point. But. …
Limitless.
It really pisses me off because one of the cited reasons was the fan response, and the fan response was that “it’s too unrealistic.”
Oh you think?! The show about a magic pill that makes you super smart isn’t realistic? Fuck off! Let us have some fantasy, FFS.
Carnivàle had so much potential :-(
Legolas was good but the faerie wasn’t as solid. Still totally entertaining though.
There’s an outline floating around online of what they had planned for the next 3 seasons
The Peripheral. Cancelled due to the writer strikes. Excellent sci-fi show. Would have loved an extra season.
Pushing Daisies… but it might be coming back? 16 years after being cancelled?
Really?
That show was great. I just rewatched it a couple months ago :)

The Venture Bros. Adult Swim cancels their best show for what? More Rick and Morty. That’s just sad.
Still firefly, even against Community.
There have been a few animated shows, or other shows like Community, but they committed slow suicide before finally dying. Firefly was still peak when it went out.
Yeah, it sounds cliche nerd wanna-be, but that was the first show I thought about, too – Firefly.
Carnivale.
It was one of the best shows ever made, and they cancelled it on one of the biggest cliffhangers in television history.
There’s a treatment floating around online of what the writers had planned for the next 3 seasons
The OA. That was the cancellation that really turned me off Netflix and streaming more broadly, and changed my viewing habits.
they cancelled castle like a month after i started watching it
At least theres a bunch of episodes. Its a shame Stana and Nathan had issues as it really hurts the last couple of seasons.
Only one I can think of right now was Constantine. I actually loved that show.
