The 1960s saw the release of many classic horror films, including 'Psycho', 'The Birds', and 'Carnival of Souls'. My favorite 1960s horror film is more over the top.
A 4-year-old named Kevin injures himself while home alone with his 6-year-old sister, Kaylee, and the movie masterfully recreates the the unsettling feeling of a child's twilight world.
