I like zombie flicks better than I like plain supernatural. I guess it just does more for me.
The Ring scared me shitless when it came out (I hadn't watched many horror movies back then). I recall that my sister and I went to see it together, last session of the day on a Friday 13th.
First scare of the night: after the movie ended, I went to the bathroom (just in front of the exit). Just as I came out, there was this flash on the screen (I could see it since the door was half-open), it was the film rolling out.
Second scare of the night was on my sister. She'd gone to bed with her lights on, door open, TV off. She woke up with the lights off, the door closed, and the TV on a movie that, incidentally, happened to picture a barn with a well in front of it.
