Whenever my girlfriend leaves town to visit her family - like she did yesterday - I take the opportunity to watch movies that she'd never stomach, like Robert "Bob" Clark's Black Christmas.
With little expectations, I watched this 1970's Canadian horror gem - also known as Silent Night, Evil Night and Stranger in the House - late last night alone in my apartment, which is the best way to watch many horror movies. The methodical cinematography and slow narrative structure create a truly suspenseful experience that produces genuine horror. The enjoyable female characters and general lack of gore, which plagued a lot of horror and especially slasher movies that came after, bolsters this film.
All in all, a near solid horror movie that established a lot of the elements that are now cliche in slasher movies.
