Out of all the shows aired on PBS Kids that try to teach kids morals and life lessons, Caillou is probably the worst. The only thing that Caillou (both the show and the character) show kids is that if you scream and throw a loud enough fit, your parents will eventually cave and give you what you want. It does this under the guise of teaching children about growing up and how using your imagination can serve you well. Not recommended for anything besides surface-level entertainment value.
