Antichrist was profoundly haunting, and deeply disturbing especially on a purely visceral level. I would not want to be Willem Dafoe in that movie. I don't know if I'd call it a "horror" film, though, but more of a psychological drama/thriller with some very grotesque moments. I honestly think it is a film that defies categorization. Them, a French horror film, was also very haunting and creepy. It had a distinctive Children of the Corn-esque feeling and that simple image of hooded intruders was very unsettling, plus that echoing like choir of "Will you play with us?" sent shivers down my spine. The Strangers, a similar concept, was also one of the more gradually suspenseful horror films of the past ten years. It reminded me of a lot of the 70's horror films like The Last House on the Left. Zack Synder's Dawn of the Dead was one of the better remakes. Very effective. 28 Days Later and 28 Weeks Later are both very unique and creepily tense. The first Saw is great. The sequels are garbage. Trick 'R Treat wasn't the Second Coming of Horror that a lot of people proclaimed it was and spasmed over but it had a brilliantly clever screenplay. Not a lot of scares so much as twists and turns. It was more of a fun, entertaining horror film like Creepshow.
