As a cultural movement, the Italian Renaissance affected only a small part of the population. Italy was the most urbanized region of Europe, but three quarters of the people were still rural peasants. For this section of the population, life remained essentially unchanged from the Middle Ages.
Although I enjoyed the book, The Hellbound Heart, the movie version, Hellraiser - with the awesomely cheesy blue and yellow 80's FX - is a bit better and mainly because it was more fully realized.
Black Christmas also predated most slasher flicks and the use of point of view shots as the killer. Black Christmas is said to be based on real murders that occurred in Quebec around Christmas time, however a search for these murders leads to little detail. The movie is more than likely solely based on the Babysitter and the Man Upstairs urban legend.This urban legend originated in the early 1960s.
