I don't mean
just series that aired a few episodes and were cancelled like:
Mercy Point - Got cancelled after only 3 or 4 episodes.
Space Rangers - Cancelled after 6 episodes.
Otherworld - Bounced around the dial and never really given the chance to get an audience. Got cancelled mid-way through season.
But also series that went as far as the pilot stage then stalled like:
GENESIS II/PLANET EARTH - Gene Roddenberry's failed attempt to bring a post Star Trek SF series to TV. Ironicly it was a post-apocalypse series, which may be why it never got green lit.
THE OSIRIS CHRONICLES (aka Warlord: Battle for the Galaxy) - Had potetial. I actually reviewed this one a while ago (

ISLAND CITY - At least I think that's what it was called. The actor from Will and Grace was in this. He played a number of different CLONES. Alas this is yet another failed post-apoc series. The pilot made it to air as a UPN movie.
I'm sure there's probably more out there.
