Jurassic Park

What does this film tell us about the benefits and risks associated with reviving long extinct life forms? What is the interplay between scientific inquiry and entrepreneurial efforts in the film? What are the competing motivations in such cases? Do such projects as the real-world enterprise "Pleistocene Park" run similar risks while offering their possible benefits? If so, how might they be mitigated? Is it, in principle, impossible to predict consequences of playing with complex systems, such as eco-systems? If so, should we abstain from doing so?
