I love the artistic design behind this show. It encourages children to make art, and who wouldn't like that?
When you do watch this show though, you might realize that there's hardly a moment of silence in this show. There is a lot of noise - relaxing noises, weird noises, and even noises like shouting, wowing, and laughing. It's a myriad of noise, noise, noise! You hear a new sound effect every single second. It has the feel of those ASMR videos you find on YouTube, only each ASMR is extended into 22 minutes and shown on television. I guess that preschool children like this show because of the weird noises that would appeal to them and the fact that art is being made on the show. However, I think adults and teenagers would like this show too.
Overall? A great show for any age (unless you're just not into a show with a myriad of weird noises).
