The Crazies might be the first of this type of horror film, were the people don't attack other people like a slasher film , but they kill themselves. I ask why has this type of horror film become more popular in the recent years, like 'Suicide Club" 2001, the Happening (2008) ? are they promoting mass Suicides ? Maybe they could have called the film the 'Werther Effect' Since this film the infection / copycat effect, is visual , you would think a blind person or a bunch of blind people would be the leads .
