For me it's the element of realism. The chance it can happen. For example, Wrong Turn had possibilities. Anyone who's driven thru Logan County, West VA. knows what I mean. There's guys out there in the backwoods who could have played the inbreds and not needed any makeup. Lol.

I grew up when drive-thru's were still a big deal on Friday/Saturday nites. Double feature B-horror movies. I'll never forget going to see a horror movie at the old towne theatre. There was an ambulance outside with the lights flashing. People dressed up like nurses taking blood pressure for movie goers standing in line. Lol. Near the end of the movie when the biggest scare of all was about to happen, the projector stopped, a clock ticked off 60 seconds with the sound of a heartbeat pounding in the background, and a warning was put up on the screen that once the movie resumed the doors would be locked and no one would be allowed to leave. That was great, a little over the top, but very effective. I miss that. 99% of today's horror movies are simply special effects with a lot of gore.
