Contagion, like “Titanic”, is a movie where you think that you already know the story: A pandemic infects hundreds of millions of people. What you don’t know is how well that story is told and how interesting some of the characters are. If you aren’t at least a slight germaphobe before watching the movie, you will be afterwards. The movie constantly reminds us of the different ways that disease can spread. In a world with SARS and H1N1, the movie is very relevant.
