Seeing Halloween when it first came out made me realize I loved being scared. Halloween wasn't gory, just scary.
The first 15 minutes or so of Scream scared the snot out of me. It was just suspenseful.
Who can ever forget the moment of realization in the first When a Stranger Calls?
This weekend I saw 1408 and The Happening. I liked them both well enough, but wasn't as scared as I'd hoped. The Happening was a bit hokey but there was a creepiness about it that I loved.
The Other (1972) was a nice creepy little movie.
When the girl spider walks the stairs in The Exorcist, I still get so creeped that it scares me.
