There are several "I hate Caillou" pages made on Facebook, posts saying that Caillou is a ripoff of Charlie Brown, numerous parenting blogs criticizing the series, and petitions on Change.org for the show to stop airing. A common criticism towards the series is the "petulant, manipulative and spoiled" behaviour of the titular character, the lack of consequences Caillou is given, and the "poor parenting" presented in the parent characters. As Hopper explained, "This has understandably led to theories that this is an accurate portrayal of Canadian parenting and that Canada is raising a generation of psychopaths. Or that Caillou's parents are so blasted on Canadian weed that they are unable to summon the presence of mind necessary to properly discipline their child."
