As a kids show bluey is adequate. However, I suspect its secret is that it's really a show for parents with young children that just happens to hold the attention of kids. My daughters like bluey (ages 3-8). But they also enjoy many things on TV and bluey doesn't stick out that much. On the other hand, I happened to be in the room for an episode where blueys dad is having a hard time making some sort of cake and blue…
Fwiw my kids (9 - 12) watched every episode at least 4 times already by now. Especially my youngest thinks it's 10x better than anything else on offer. In terms of categories, there's basically Bluey, and everything else. Just to say, tastes differ.
I agree it's a great show for parents too but the idea that it doesn't stick out much for the kids doesn't resonate with me. There's so many details, so many layers, so much to discover.
