A collection of Scary

there was a recent study i read about regarding online dating. it described how the best way of matching people was using just a couple of simple questions, one of which was "do you like scary movies". apparently, matching answers here was the best correlation they found for successful matching. i find that odd. it's a binary choice.
also, i wouldn't know how to answer the question. i like good movies. the genre is less important to my liking of a movie than the goodness of the movie. i like good scary movies, i dislike bad scary movies.
i think that the point of the question is more about being scared. i don't really get scared by movies any more. some, like the butterfly effect, are truly harrowing, without being scary. also, the butterfly effect has complete nudity in it and yet is rated as a 15! that is scary.

yesterday i got very confused while driving. the man in front of me was driving frustratingly slowly down the road for about 500m before finally braking and pulling over into a bus stop without indicating. i fired one blast of a horn at him as he slowed without notice. as i drove away i heard a horn fired. i don't know whether the man was retaliating or someone else found his manner dangerous and required him to be blasted in the head with an warning sound.
i hope it was retaliatory. you can tell a lot about a person by the horning that they do. some people use it as a toy (e.g. eygpt, new york city), some people use it accidentally leading to awkward situations (me), some people never use it, some people blast it due to anger, and some people wait until you are far enough away before using it e.g. the man in my story.

i expect that this would be a much better way of finding out what people are like, instead of asking whether they like good movies.
