I love a really scary, spooky movie, and so does DH. But all too frequently we are disappointed. Blood and guts/green vomit/rotted corpses/gunge do NOT make a scary movie! The ones that have scared the living shit out of me and stayed with me for years are films like the original The Woman In Black and The Others - no blood or gunk to speak of, just really well-written, well-paced menace and mystery and great characters.
