Your favorite image in a horror film?
Bill Chambers, over at Film Freak Central, sums up my favorite image nicely [it's from "Psycho II ,incidentally, a less-than-masterful movie with one incredibly masterful moment]: "The iconic closing shot of Norman standing on the steps to the Bates house, silhouetted against a tempestuous night sky, "VACANCY" sign glowing in the darkness, says nothing less than that he's fucked. We're all fucked."
"Psycho" is the better film, obviously, but, the above image is the first image I think of when someone mentions "Psycho."
