Television

Threshold really should have gotten more than one season. Unfortunately, I don't think anybody's ever heard of it.

My name is Earl, super disrespectful to end on a cliffhanger after 4 seasons

Lazor Wulf. Two seasons, with a forced change in animation studios between seasons, didn't give the show enough opportunity to grow.

Tuca & Bertie and Firefly as well. Maybe Lower Decks too

4400 both version, pretender, x-files, clarice,

Inside Job

If streaming shows are fair game, Final Space. So much passion poured into such an excellent production and Netflix axed it after 3 seasons.

The Pretender. Mostly because they had just had a huge cliff hanger. And the made for TV movies never got aired in my country.

Outer Range

freaks and geeks. unbelievably stacked cast but the network never gave it a dedicated time so no one knew when they could watch it. then it got cancelled before they aired half the episodes citing poor viewership

Last Man on Earth

Sort of counts, but KOTH.

Fox took it off the air FOUR episodes from the finale to "make room for The Cleveland Show" of all things, the worst offering from those Family Guy clones imho.

Luckily, Adult Swim was kind enough not only to pick up KOTH, but to air those last missing episodes as well, and I have it all torrented by now of course and it was easy to find, but still, fuck Fox for that one (amongst other things, but I want to punch the specific exec that decided to do that right in the eye just one good time.)

I liked Danny Devito's Little Demon, but it only got one season. :(
