Constantly miss identified dinosaurs and poor scripts.
There were two obvious miss identifications in the first episode alone. The first using the incorrect "Jurassic Park" Velociraptor. http://en.wikipedia.org/wiki/Velocoraptor
The second being the Megalodon. http://en.wikipedia.org/wiki/Megalodon. Which looked more like a Kronosaurus
I assume there a many more but I cannot bring myself to watch anymore. Better research on the part of the writers would help this series immensely.
The fact that their science teacher is a seemingly immortal "velociraptor" who has lived millions of years, can apparently shape shift, and has telepathic powers does not help ether. That and the constant puns from the villain's name and company are both stupid and extremely unnecessary. There were cartoons made in the 80's with drastically better plots than this. Transformers, Thundercats, and bloody He-man to name a few.
