I've watched this several times overthe 7 years it came out & ive read the viewers comments & at that at the end of this movie it seems as it would be a part 2. Their still looking for a cure, There has to be more humans somewhere in the world who are doing the same, at some point these separate groups need to find each other. Im only hoping there will be another movie for this or either make it into a tv series eith a few seasons to it.
