This episode is good, despite the real goof in the storyline: caves don't collapse because of loud noises, mines do. Having the hero unable to shoot the monster because the cave will collapse is pretty silly. it's the kind of failed plot device that King is known for because he refuses to do the proper research when he's writing. In 'Salem's Lot, he had a character bragging that his .410 will stop an elephant, when a .410 is a very small bore shotgun, relatively weak as shotguns go. King is a genius but lacks the proper discipline, even at this late date in his career, to research his subjects.
