I did see this series premiere last Saturday and I thought that it was pretty cute. I can see why people think that it's a Pokemon clone, but it seems different enough in my eyes not to be a copy-cat. From just the first episode, the only similarites I saw with Dinosaur King and Pokemon are the character designs, mainly for the main character and the villans, and the fact that it deals with battling monsters/dinosaurs. In all honesty, I see this series as more as mixed elements of Digimon and Dragon Drive, except it has dinosaurs instead of monsters.
Anyway, it seems like a cute, fun series to me. At least it will give me a chance to watch something interesting while I'm bored on Saturday mornings.
