A film I loved when I was younger, The Graduate only works for me if I view it as a prequel to Sam Peckinpah's Straw Dogs.
Just one of the local movie theaters I frequented during my year stationed at Fort Hood, Texas. Only two screens, but they were huge compared to what you find in so many of today's multiplexes.
I love each of these films, both of which provided me with years of nightmare fuel during childhood (and beyond), but, come on...an R for Psycho? Overkill.
