What are your opinions on the animated children’s TV show Caillou?

I have not watched it, but have heard some very strong responses to it from parents of young children and they have not been positive. It has a 4.0/10 score on IMDB, which is telling.  But slightly higher than Barney (at a shocking 3.9/10.)  Clearly, there is room in the early childhood programming world for something better.
