Late, but I agree with everyone else when I say that Clarence is underrated and overhated. So what if karens say that it's "dumb" or "horrible"? It's EXACTLY how kids are. I know that there are some rather... risky things that the young cast does, but it just... makes you feel like a kid again.
What makes this show amazing is how the episodes stand out one by one, their characters aren't too dislikable and the animation is unique and quick-paced. Clarence makes an amazing protagonist due to his happy attitude and willingness to make things fun, and Sumo and Jeff make the perfect supporters. Sumo is the wild child with scrappy solutions and a hyperactive attitude, while Jeff is the smart neat freak that is afraid of anything dirty.
Overall, why this show is amazing is that it nonetheless keeps children entertained and adults amazed by how it makes you feel like a kid again. I suggest that kids above the age of 6, or kids of an age from 9 and up with younger siblings watch this amazing cartoon.
