Also loved the soundtrack, but now I have a greater appreciation for Elmer Bernstein’s scoring, too. It was my 17 year old daughter’s first viewing.
This is a great lesson in atmospheric horror. Nice, slow building tension with mysterious happenings. Frequent moments of "did you just see that thing move?" and "Behind you, Harry Potter!!" spookiness. I jumped a few times and had goosebumps at least once. I know it was based on a stage play per other people's posts, and I'd love to see it. All in all, an excellent return of Hammer Studios.
