Title: Terrible!
Review: Jurrasic Park had the excitement of pushing the envelope of science and technology in a direction of credibility. It may be years before something like that would be possible, but, certainly, someday it would be possible. None of that here. Parallel universes? In particular, dismissing the effect of an action in the past as having no relevance to the course of subsequent history? There is no science here, just a contrived bunch of nonsense reminiscent of The Celestine Prophecy. It is juvenile, pure science fiction without basis in any science at all. It is for children, except for all the violence. A real disappointment from an aouthor who was able to capture the imagination so effectively in Jurrasic Park.
