I was lucky enough to catch this on TV the other night and it's left a huge impression on me. Until then, I had only been truly scared by two films - The Haunting (1963) and The Woman In Black. This one makes it three. There's very little violence, no gore that I can remember, and no sex - because this is a film that doesn't need to rely on cheap shocks and titillation to be frightening. The build-up of suspense is masterfully handled, helped enormously by the likeable main characters who you really do feel sympathy for. The use of sound is the most effective since Suspiria, and to top it all there's the joint-scariest ending that I have ever witnessed.
