YMMV / Caillou

  • Alternate Character Interpretation:
  • Base-Breaking Character: Two clear camps exist for this: One camp finds Caillou's gentleness charming; the other finds Caillou wimpy and irritating. Also, whether he's a nice kid or a Spoiled Brat.
  • Germans Love David Hasselhoff: For reasons unknown, Caillou is extremely popular in Turkey. Yumurcak TV, the Turkish children's TV channel that carries the show, airs a one-hour two-episode back-to-back slot at 7:00 AM and three additional half-hour slots through the day, seven days a week. To drive the message home, Caillou toys are abundant in Turkey.
  • Memetic Mutation:
    • There are Caillou YouTube Poops out there. Many of which are ones of Caillou's tantrum from the circus episode. A notable series of poops come from Mr Poop Meister, whose poops often include rampant F-bombs, child abuse, and one episode pooping "Train Trip" was removed because of a joke at the end portraying Caillou as Osama bin Laden, the mastermind of 9/11, complete with George W. Bush addressing the nation about the attacks, Barack Obama announcing his death, celebrations in the street, and even John Cena's announcement at the end of Extreme Rules 2011.
      • And, who can forget CS188's Caillou YTPS!
    • YA BOY CAILLOU, a Twitter about gangsta Caillou, and the Caillou rap (explicit).
    • Of course, there's Evil Twin Caillou on Twitter.
    • And last but not least, let us not forget the fact that Caillou (or rather, "Kaylew") has become more or less the unofficial Series Mascot of grounded videos.
    • The anime One-Punch Man has a protagonist that looks remarkably like a grown-up Caillou, so people are calling it Caillou Shippuden.
  • Periphery Demographic: Mostly parents who monitor their children's TV viewing. But others came naturally.
  • The Problem with Licensed Games: The iPhone apps. The audiobook app pretty much ripped the audio from the TV series and shoehorn it into some mediocrity animated storybook, while the new edutainment app is cited to be repetitive and limited in interaction. One of them is even an Allegedly Free Game.
  • Seasonal Rot: Obviously many would agree the show was terrible from the beginning, but while Caillou constantly being a Bratty Half-Pint in the first two note  seasons, by the third he had calmed down noticeably. By the fourth, he had lost all brattiness, and to make matters worse, was constantly imagining things instead, the previous lack of which had been one of the show's few saving graces. On top of that, the animation became much worse. Thankfully, season 5 has dropped the Imagine Spot gimmick and restored some of Caillou's signature brattiness.
  • Snark Bait: Boy, has it become this!
