The Muppets was cancelled after just one rebooted season at ABC, but why did it fail? Frank Oz, the celebrated puppeteer behind several Jim Henson characters, has pointed the finger of blame at the writers, per Variety:
My brothers, my sisters, were in there [as the puppeteers]. They did the very best they could. But essentially, they were working with scripts that other people wrote. They had to do it the way it was. If it was given more air and they trusted the performers, as we had air, it would have come alive more. Those abilities, to riff and be smart enough, weren’t appreciated.
