Caillou

Caillou is a Canadian educational children's television series that was first shown on Télétoon and Teletoon, with its first episode airing on the former channel on September 15, 1997; the show later moved to Treehouse TV, with its final episode being shown on that channel on October 3, 2010. The series is based on the books by Hélène Desputeaux. It centers on a 4-year-old boy named Caillou who is fascinated by the world around him.

Why It Sucks

 * 1) Almost all of the characters are really poor:
 * 2) * Caillou, the main protagonist of the show, himself is an unlikable character. For example, he misbehaves constantly without being told off; in the fourth and fifth seasons, Caillou, despite being significantly better-behaved, is very bland and became a huge Gary-Stu.
 * 3) ** As a matter of fact, his whining had a negative effect on kids' behavior.
 * 4) * His parents, Boris and Doris, are no better. For example, they rarely punish or scold Caillou for his actions, even when he deserves it.
 * 5) * The rest of the characters are bland and have little-to-no depth whatsoever. For example, Leo and Clementine are generic friends, and Ms. Martin is the generic teacher.
 * 6) The voice acting ranges from bland to just plain annoying.
 * 7) The art style is off-putting and questionable. For example, the backgrounds are never fully painted. The color palette is also too bright and unrealistic. Granted, this is likely done to resemble a children's storybook; the first season even features a more realistic art-style in the framing device, but that was dropped from Season 2 on.
 * 8) The animation in later seasons is horrendous, as it is very stilted and lazy. This was likely done to cut corners and save money.
 * 9) The show introduced interesting characters like Andy and Alan only for them to disappear later on.
 * 10) Some questionable-at-best morals; in the banned episode "Caillou Goes Around the Block", for example, Doris allows Caillou to go out on his own, which is a very bad decision.
 * 11) In later seasons, the morals are shoved down the viewers' throat.
 * 12) The plots are extremely clichéd and stale as well in the later seasons.
 * 13) Slow pacing.
 * 14) Awful Theme Song.

The Only Redeeming Qualitye

 * 1) The Goanimated series, Caillou Gets Grounded are awesome because seeing Caillou get a comeuppance, is a always awesome.

Reception and controversy
Although the show performed well with its target preschool demographic, Caillou was panned from older viewers and critics alike. The titular character's misbehavior throughout the show has made him an infamous character among older viewers and parents, since Caillou's troublemaking and whining was considered to be annoying and his parents accepting his actions rather than disciplining him didn't clearly show that his actions were wrong and as such he didn't learn from his mistakes. Many parents have even claimed that their children became naughtier when watching Caillou and copying the titular character's behavior.

The series currently holds a 4/10 on IMDb and 4.7/10 on TV.com. On Google, it has a 2.7 audience rating.
