Recommendations from everyone

What FF movie has absolutely terrified you? I feel like I've burned through every FF movie I can find, but I can't get that scared feeling. I really enjoy FF set in the woods, preferably with a monster/supernatural, rather than a person as the source of terror. Any recommendations would be great. The first time I ever watched Hellhouse LLC, I got some scares out, but you can't get it again on a rewatch.
