In general I consider myself a hater of horror movies. However, there are a couple of genres of horror films that tend to work better for me than others, and those are mysteries and thrillers. Black Christmas has some elements of both of those genres. The inventive use of the handheld camera as the point-of-view for the killer worked brilliantly for creating tension, and allowed them to fool you at times that the killer might be watching when he actually wasn't. I found the movie progressively more tense, and even though many of the things found in this film have become tropes of the genre, they still work well here. I like that it takes some time before we nail down which of the girls will be the "final girl," and that there are a lot of male suspects introduced that allow us to speculate about the identity of the killer. The ending was what I expected in one way, but then completely surprised me in another way (which I won't spoil.) I have to admit, even though I like how the film is constructed and respect the groundbreaking techniques, it's still not a style of movie that I will ever love. For big fans of horror, I think Black Christmas should almost be required viewing, because of how it inspired so much that came after it. For those who don't like horror, you might still enjoy it (because there's very little gore,) but it delivers some effective scares.
