Thanks to a conveniently spliced youtube video posted by Rich Juzwiak at fourfour.com of all of the greatest mirror-scare scenes of all-time, I was reminded of how much untapped hatred I have towards this occurence.
Surely horror filmmakers know that this is the most convenient, overused and played-out gimmick in the genre, so why do we get 4-5 of these a year? (The Unborn and Orphan come to mind.) Is this like the visual equivalent of the Wilhelm Scream?
Jeff Wells at Hollywood-Elsewhere also took offense, claiming that the grand-daddy of all mirror-shock scenes is the one from Roman Polanski's Repulsion (1965), which is absent from the video.
