Actuallly a rather poor series. It has a lot of very original thought and some great special efffects, but the stupidity of so much of it is just too hard to swallow - one simple example: at one point when the players are down in an undergorund lab with what they say are totally impenetrabal pollycarbinate windows that the creatures cannot possibly break through, well, they do break them, but a few scenes later, these same creatures cannot get through simple glass doors on the front of the building! I would not recommend this show to anyone over 12.
