I don't think enough people have seen Black Christmas on the site which is sad but it's also the way this works. Although I feel like I need to defend Scream now. It's a landmark flick, not to say Black Christmas isn't but its influence was co-opted by halloween which isn't fair but it's what happened. Scream is possibly the best horror flick of the 90s (which isn't saying much I guess) and it rejuvenated horror and spawned a long list of imitators but never lost its legacy or place in history. Smart killers, smart satire, smart characters who still fall for the horror tropes even with knowledge of them, and all of it works. Scream's impact is still felt till this day breh.
Black Christmas inspired Scream how can you say Scream was more influential? Black Christmas inspired tons of movies and started the whole whodunit theme in horror movies. Black Christmas is the serious all horror version with no comedy version of Scream while Scream is more a spoof of Black Christmas. Black Christmas is one of the most scariest movies of all-time and has some of the most realistic and disturbing kills in horror movie history.
