I do happen to know a few ill-fated cartoons that a select few might know.
Does anyone here know an ill-fated cartoon known as Ellen's Acres? This imaginative delight used to air on Cartoon Network back in January 2007 (and aired on CN Video as a launch title before it's TV debut), and only lasted 4 weeks on Cartoon Network. The series died due to a bad timeslot (9:30AM EST on a weekday morning to be exact).
I also do happen to know an ill-fated toon known as Click and Clack's as the Wrench Turns. That cartoon series starred Tom and Ray Magliozzi, the same two that hosted a car talk show on WGBH Radio. It did air on select PBS stations back in Summer 2008, but died within a month and a half of airtime (and unpopularity).
What about the New Woody Woodpecker Show back from 1999? While being one of the later-era Fox Kids series, many of those series never lasted long before Disney bought out Fox Family Productions back in 2002. It was a great modern spin on a cartoon classic, but never made it to a newer generation of cartoon fans.
I could continue, but I didn't want to bore you guys.
New Woody Woodpecker was briefly on Netflix Watch Instantly. It was alright, didn't see too much of it.
