Its a very well put together documentary with brilliant stop motion and scientific research done by the talented creators and paleontologists (at least what they had available at the time).
The narration is calmingly spot on and informative. The prehistoric animals look and sound almost realistic.
Despite some of the dated info, the egg-laying plesiosaur Woolungasaurus and Megaraptoran - Rapator depicted as the Abelisaur Carnotaurus, I never get bored of this 26+ min video.
I'm sort of an expert myself but I always like taking the time in seeing how far experts have come since the documentaries release (1993).
