Forgive me parents, but I really like Caillou. This is another one of the animated shows from my childhood that I'm familiar with. I like the characters, the artsy environment, very colourful. The puppets are my favourite segments overall. Yes, the show was changed through time, and of course, Season 1 was cookoo, goofy, and wild, but misunderstood because everyone thinks Caillou is mean, and toxic, which was too early and unjust to judge, because he is a realistic 4-year-old child who is struggling and learning about life, and I wish people would understand that. However, Season 2 was so-so, Caillou is basically growing up a little, and yes, he has some problems, but Season 3 was better after that. Season 4 is my favourite, despite the puppet segments in Season 2. This season is when I say that Caillou basically grows up a lot more, he is about 6 or 7 years old in this season, and this season is fun, creative and versatile when it comes to learning and doing stuff like making pizza, ceramics, construction, rock sculpting, and playing professional music instruments. Super dope! But Season 5 is basically a prequel to Season 4, because Caillou learns about things, that he already learned in Season 4. Overall, It's a good enough show. and I rate it 7/10.
P.S. Because he is bald, I always thought that Caillou looked like a doll, and I also wished that I live in a house like Caillou's house.
But seriously, the new series of Caillou that WildBrain made that you see on YouTube is TRASH. Only watch the good, original CINAR and Cookie Jar animated show and buy it on VHS and DVD because they have the best quality. No Joke.
