It's not that bad, it's educational, mostly repetitive and predictive, (sometimes), but interesting! I learned about many varieties of dinosaurs and I learn some vocab, Okay, but it's kind of boring, it's not that humorous, I think they should have more funny skits, a time tunnel that sends them to the modern era, and an April Fools episode. The dinosaur poop episode was weird too. Its pretty fictional, you know it's not real. I like how they combined the things too, but sadly, it appeals more to boys, and I'd categorize this 3-7. I just wish Craig Bartlett would stick to Hey Arnold..
