Many are too young to remember a time when a mentally troubled killer was anything but an unstoppable monster. These films from the 1920s to the 1950s were far ahead of the psychiatrists, police, and the religious leaders of their era, in insight and sensitivity. Psycho was a turning point, and in a way, a downturn. Hitchcock winks at the audience, and Norman Bates leers at it. You might not be able to tell what the right attitude is from the listed films, but prepare yourself for a whole lot of problematic masculinity.
