Based on the series of books that began being published in 1989, “Caillou” follows the adventures of an imaginative four-year-old who livens up his normal daily experiences with dreams of airplanes, rockets, and more.

The series premiered in 1997, producing five seasons between then and 2010. Episodes have continued to air in reruns on a variety of children’s networks, including PBS Kids in the U.S.

Despite airing for over two decades, and apparently amassing a devoted child audience, “Caillou” has long been scorned by parents and others, who celebrated the news of the show’s cancellation on PBS Kids.

In a 2017 article, HuffPo dug into the notoriously divisive cartoon character, with parents criticizing everything from the background design on the show to its annoying theme song, complicated story structure, and “nightmarish” colour scheme.
