This is a cerebral movie. Many complain about having too many characters, but these characters serve as illustration, the main character is the pandemic, that is explored in non sensationalistic but still interesting and compelling way. The most scary thing about the movie is its realism. Yes, this is what really would happen if there were a pandemic. Not everyone would die, there would be no flashy helicopter drama, but it would not be a pleasant experience either. This is a good movie but perhaps not for the seekers of cheap thrills.
