Graveyard Shift is a short story by King, also found in his Night Shift compilation. It’s eerie, atmospheric, and gross as hell! The story is quite simple. A group of men who work at a textile mill agree to work the graveyard shift to clean the mill’s basement to earn extra money. While they’re down there, they realize that the basement has been infested with rats, many of whom have mutated into something horrifying.
Yes, it’s a simple story, but very effective in its horror. The movie is, again, very loosely based on the short story, and I cannot, for the life of me, help but wonder why Hollywood insists on changing what makes King’s stories SO good in order to make them more “commercial”. This is why King’s work has more bad adaptations than good ones.
