By someone who is in the cave. It's the type of movie in which the bats attack quickly, in packs, and kill their prey literally in seconds. Unless, of course, their prey is one of the leads, in which case the bats stop flying and start sneaking around on their hands and knees, crawling ever nearer. Actually, there aren't too many movies of this kind. It's as if the screenwriter had never seen another horror movie, ever.
Every cliche is used, down to the ticking clock at the end.
The whole movie went so far beyond cheesy-bad that it was an exercise in patience to sit through to the end. We expected to laugh at how bad it was, but didn't realize that a studio would let something this bad out of the can. After the movie, my headache returned full-force. I had to stop off at Osco on the way back to Lee's in order to pop a few more Excedrin in order to keep myself sane. Eventually, I felt somewhat human again.
