This is some kind of liberal's rescue story for saving mankind from themselves as a result of their environmental sins. As is all too common these days, the script-writing was left to terminally-lazy intellects who could simply not make the effort to write even a vaguely credible physical background to a poorly contrived plot. So we are left with what will become one of the most infamously badly construed sciency "love stories" (which is only the director's opinion - and he failed at getting that right as well).

This movie was a massive disappointment.
