Brian Horiuchi's "Parts per Billion" is about rising chaos as trade winds blow toxins from the Middle East westward, but the focus is on the characters and how they try to get on with their lives amid the disorder. I interpret this to mean that the movie's gist is that we have to avoid giving into sheer hysteria when something bad happens. We've seen how psychotic people can get when they're scared, whether with 9/11 or with Ebola. As for the movie itself, most of it came across as a little slow. I did think that "Outbreak" (which emphasized the biology) and "Contagion" (which depicted the government agencies as competent*) were better.
