This movie is just so creepy. There is nothing particularly 'unworldly' or 'Martian' about what they are experiencing. It's more like a haunting or a reality shifting. Reminds me of another film from the same era, _The Haunting._ Like that film, there is a psychologization of the horror - it all seems to be taking place within the mind of each character rather than an external reality, and you are never quite sure where the menace resides - within or without. I found it to be very effective. Also, the fact that they filmed it at Greystone Mansion a known haunted house. I don't know if the producers did this to extract better performances, or it just was a practical consideration, but it just adds to the overall creepiness and uncanniness....
