Hmmmm... Suspense but with little gore.........
- Ils is a fantastic little French horror movie that has a LOT of suspense, but not a huge amount of gore.
- The Orphanage is also a good view in terms of suspense and intrigue.
- Crazy Eights is a good little ghost story with quite a bit of suspense. It's low-budget, but incredibly well-done.
- The original Black Christmas (1974) is so incredibly underrated, most likely because it was ahead of its time. It is a masterful suspense film that creates that sort of stoic, emotionless Big Bad that you mentioned enjoying.
In terms of fantastic psychological horror...
- Session 9 is an absolute must-see. Brilliantly creepy and well done (also done locally - the asylum is only about an hour or so away from me)
- Jacob's Ladder is a true classic. Talk about tortured and incredibly well-done.
Possession horror... Hmmm... Leprechaun and Chucky aren't really my cup of tea... Maybe you should check out the Nightmare on Elm Street and Candyman movies (I lump them into that category of absurd horror).
In terms of stoic and emotionless Big Bads, no one has surpassed Michael Myers in terms of my own horror bank. Check out the original
Halloween (1978).
If you get around to watching them, please, let me know what you think.
