Stephen kings graveyard shift (movie) review

This movie was on TV one night because they were doing a stephen king marathon which had Cujo,Dreamcatcher,Christine,Silver bullet and Thinner which were all very enjoyable. This one was the last film in that marathon so i was very excited. Here is the plot of the movie. So a bunch of people work at a graveyard mill in maine which is starting to get infested with rats so all of a sudden people start dying and getting their hands eaten off until this moron says hey everybody let's go into the mill so they hire an exterminator to help them kill a giant mutated rat bat creature. The movie is complete utter garbage and i suggest for you to never watch it ever instead read the short story
