I wasn't sure where this movie was going. About an hour and 20 minutes in, it shifted to something else. And I actually got interested. But I think the story could have been told in a more creative and cohesive way. It isn't - by far - the worst science fiction movie (although the science was seriously, unforgivably, shaky at the beginning. Like Irwin Allen-level shaky). That said, I don't understand the criticisms of Katee Sackoff, who did very well with some flimsy material, and who carries most of the movie to a level it's unworthy of. The movie definitely does not have the weight of something like Battlestar Galactica, in which the near-total destruction of humanity is portrayed in a much more nuanced, believable and enormously tragic way. In that Peabody Award-winning series, Sackoff was a standout, even among her Academy Award-nominated peers.
P.S. The Director seemed fascinated by the CGI capabilities of particle systems and Adobe After Effects. :)
