NBC's God, The Devil, And Bob, ABC's Clerks: The Animated Series and The WB's Baby Blues are among TV's notable animated failures.

Baby Blues- two seasons (albeit the second wasnt aired until adult swim picked it up)

Mission Hill- one full season

The Oblongs- two seasons


Maybe these series failed on their original networks but once picked up by Adult Swim they all gained a decent following (especially Mission Hill) and were broadcast for years. Far from being on the failure level the likes of "Capitol Critters" and "Fish Police"

Capitol Critters was TOO ahead of its time...if they poked-fun at the Clinton Administration and was part of that or The GWB era, the show would've been a success.

Some were good the rest were awful. Especially Allen gregory.

Capital Critters & Bordertown should’ve lasted a bit longer

I'm glad Bordertown bombed. It was garbage.
