Dinosaurs, Portals, and the BBC, Oh My!!! Great show for the whole family, though I wouldn't show it to very young children, as it may scare them. No nudity, or F-Bombs, to worry about. There is violence, but what can you expect when you're defending yourself against prehistoric creatures. I would suggest watching the whole series in order. I've already purchased the first three volumes and will purchase volume 4 as soon as it becomes available.
