One of the stranger and most poorly-marketed films of the 70's is Nicholas Gessner's adaptation of Laird Koenig's 1974 novel 'The Little Girl Who Lives Down The Lane'.  Far from the horror film the poster and trailer tried to sell audiences on, it's instead an unsettling but realistic portrait of a young girl in an uncertain situation, and a film that I find particularly resonates with people who themselves were 10 or 12 years old in the late 70's.
