The basis of the plot is a good one, though not original. The movie movie had a few plus points, but the negatives were big. 1. Will writers/ directors please ,stop making every contagion a zombie / rabid virus, try using some imagination. 2. The pace of the movie was at times excruciatingly slow. 3. Why do Science Fiction horror movies almost all follow either Alien, Event Horizon or the Thing, and some follow all 3. There are plenty of great writers out there with originality, stop playing safe, it's boring.
