There are certain things that the film industry avoids because they’re viewed as cliché, but this film is the original that did it well. You’ve got a large wealthy home, strangers brought together with the promise of money, and a subtly created by the simple fact that they didn’t have digital special effects software. Throughout the entire film you are never certain if there really are any ghosts or not. There are strange sounds, accidents, and more than a few surprising sights, but just enough to make you wonder, nothing definitive. This film definitely subscribes to Hitchcock’s “less is more” philosophy, and it works.
