What really struck me about the film upon seeing it for the first time was the way it captured the feeling of utter isolation in such an event, for a major part of the film the audience only follows Regina as she rides across a sun-soaked desolate downtown Los Angeles, to an almost unnerving effect. The film has a lot of beautifully composed shots like this, though more often than not the production's low budget aesthetic lets down the overall sense of composure in other places.

This sense of feeling passes once Samantha, as well as fellow survivor Hector (Robert Beltran) enter the mix, who seem a bit too relaxed in dealing with such a mass extinction event. They aren't alone, however, as the effects of the comet have also turned many people into cannibalistic mutants, who roam the streets and prey on whoever they can find. On top of that, the sisters become a subject of interest for a think tank group of scientists, who possess ulterior motives that form the film's final act.
