Pretty cool study.
I've never really enjoyed scarey movies, especially particularly dark ones. But I like some dark movies that don't have that fright factor.
OTOH, I love rides. Well, I used to, but it's been a few years. I never thought of them as scarey so much as thrilling and exhilarating. Sometimes wifey would join me and have tears running down her face. I'm just focused and anticipatory.
