Do you have a strange feeling of "Déjà vu"? Like you've already watched this movie but you don't remember when or where? You might be right if you're old enough to have caught The Outer Limits TV series and its season 3, episode 13, titled "Dead Man's Switch " (1997).
To be honest, I really thought right from the beginning of the movie that I had already watched this movie before. However it was entertaining enough and well made to rate it with a 7. Despite the number of obvious "coincidences" between this movie and the Outer Limits' episode, the "original" plot change (global virus) and ending (I will avoid spoilers) makes it worth a watch.
I understand why some people can be disappointed by the movie since it might feel like a Twilight ZoneOuter Limits episode that was way too long for the story being told.
