"Walking With Dinosaurs" was the most amazing show I've ever seen anywhere. It even out does "Jurrasic Park" as far as the dinosaur recreations are concerned.
All of the dinosaurs were realistic in the way they moved, sounded, and interacted with each other, and with the palentologist/narrator. Even though you could tell the smaller dinosaurs were actually actors in costumes, and the larger dinosaurs were fastened to long devices that probably had some sort of engine to move them around the stage, the devices didn't detract from the realism of the animals. As for the size of each creature, it was amazing to see how tiny the palentologist, and the people in the audience were as compared to the creatures. Although you couldn't really tell how big the baby dinos were, you could tell the adult dinos were ENORMOUS.
Overall, the entire show was excellent. The only flaw in the production was the flying dinosaur looked more realistic when you watched the screens than when you watched the creature itself in person.
