Caillou is made for pre-verbal toddlers - the viewers who would look up to a 4 year old lead character as a role model. Maybe not my thing, but when my kid was 1 this was one of the first shows slow and calm enough for them to start following the social cues in the plot and empathizing with characters, which I always thought was the point.
But I’m confused about why I should be dunking on a show for babies, especially when there’s a lot of kids’ programming that’s a lot more toxic, commercial, or just more poorly made. Besides, there’s decades of episodes to replay so I don’t think this make the world safe for Caillou haters (;
