Nightmare Fuel: All of the predators depicted, but Deinonychus deserves a special mention. Perhaps it's due to the awkward, messy way its feathers are animated, thanks to the less-than-stellar effects, but the animal looks terrifying, and proves that feathered dinosaurs are not all cuddly little chicks. Not helped at all by the sounds they keep making.
Special Effect Failure: The animals move ridiculously fast at times. The absurd speed of the Daspletosaurus' head as it lashes at the Corythosaurus makes the scene look rather laughable.
As a Smilodon jumps on the back of a bison, you can see its paw clipping through the herbivore.
The lighting and rendering of the animals aren't too hot either.
