The most important thing to know about Erin is that she works in the college library. The movie was filmed almost entirely on location at Bridgewater State University, with some exceptions including the library scenes, which were filmed at the Middleborough (Massachusetts) Public Library (for interior scenes) and a creepy-looking building (which we believe to be the Pratt Free School) for exterior scenes. For those who are prone to over-analyzing movies from a library standpoint this will be problematic. It is too obviously a public library, and way too small to serve the fictitious Willow Ridge State College campus. However, there were several scenes in which students were directed by their professor to use the library for research, which almost made up for any other inconsistencies.There were some long shots of the campus in which the Clement C. Maxwell Library building was visible, but it was not identified as such. It was actually rare fun to watch this horror film (something that is generally out of my genre set of things to view). The gore was pretty mild, and I was too busy identifying landmarks to be bothered by the blood, anyway.
