This movie was quite enjoyable. It had a nice blend of classic sci fi such as "Invasion of the Body Snatchers", but brought a new vision along as well. As well, the acting made it more tangible than the usual highly polished Hollywood sci fi, which I enjoy as well. I would not be against a part two, and I think that it may possible that it was done like that purposely. I think what was integral to its believability was that once the main plot line started rolling, it didn't stop. I also enjoyed that when the emotions got raw that they were palpable. I say well done.
