Halloween gives us all a chance to dress up and costumes. More important to me it gives a chance to watch and revisit horror, thrillers, gore, suspense, and just plain scary movies.
Classics that I think are great are:
The Wicker Man sexual pagan rituals in this strange british village. The townfolk surpise you with nudity, language, insinuations, and images.
Suspiria watched this for first time. Has the ultimate best murder scene. The music in this one still makes me shudder.
Devil's Backbone very good movies. Dark, mysteriously captivating, and pulls you in with an excellent unique story of a ghost. This is a spanish ghost story and a quest for revenge.
Halloween Michael Meyers at his best. Jamie Lee Curtis emerges as the scream queen.
Some favorite Modern ones:
High Tension This movie amazed me, considering I had never heard of it. French film that has the feel of small american mid-west redneck (Texas Chainsaw-ish) murders. Great movie, though final ending seems absurd.
Audition a sleeper type movie. Japanese subtitle is the best version (preserves her natural cute girlish voice which is important for the ending. Dont let the slow and happy beginning fool you. You are not watching a Romance movie. This movie will have a surprise at the end. Kiri kiri kiri kiri kiri.
