The mild Stephen King short story is turned into a mild flick as this is basically a slim-plotted monster movie that has a bunch of workers at a textile mill spending a weekend cleaning up the basement levels only to start getting picked-off by a giant rat/bat combination beast.
This isn't exactly a memorable time but it's not all bad as genre favourite Brad Dourif (the voice of Chucky in the Child's Play series) shows-up as a odd exterminator, Stephen Macht plays the "jerk" role as the foreman well and the film has an okay grimy look along with acceptable effects (which granted look a bit too fake at times).
While this isn't the worst film based on King's work (I think I'd have to go with 2003's atrocious Dreamcatcher for that); it's nothing special either and there's nothing really to it. It does open with a pleasingly gory pre-credits sequence though.
