It was the summer of 1971 when two future horror legends, Wes Craven and Sean Cunningham, gathered in the woods to shoot "Last House on the Left". Almost more important than understanding what happens in the film, it's crucial to understand the world that the film was born into. At the time it was made there was a counter culture suffering from the burnout of a failed social movement and increasingly harder drugs, and a mainstream America whose children were being decimated by the seemingly never-ending conflict in Vietnam.
