I'm a kid of the 70's before all the CGI special FX. And this is still an old school fav of mine. I love spooky Karen Black. I always had an affinity for large creepy houses, especially when they become one of the characters in the movie. This is another 70's slow burn in the haunted house genre that more than likely helped fuel my NIGHT TERRORS and SLEEP WALKING issues. Still holds up decent for it's age, but if your looking for a GORE FEST, move on, cause this won't fill your cup. If you like psychological Gothic style horror then check it out.

This comment may contain a spoiler or two -- it is for those who have seen the movie and are baffled.

I have not read the novel, and have only seen the 'edited for T.V. version (about four times). But from reading other posters' comments and reviews, it seems that many people are baffled by what the title 'burnt offerings' means and what the heck is going on in the movie. From what little I have seen on television, the theme seems to be that the house injures and even kills its resident occupants in order to renew itself. Sort of a fertility rite, where death was enacted to bring about the Springtime, or renewal. Whenever someone gets hurt, or killed, the house renews a part of itself. Minor injuries may only repair a simple light bulb, or bring a few dead potted plants back to life or restore a cracked mirror. But look what happens at the end !!

The old lady upstairs, Mrs. Allardyce (?sp) is supposedly an eighty-five year old woman'. Isn't that the approx. age of the house (in 1976? Wouldn't you say the Dunsmuir house looks about that old, built in 1891, perhaps?) When the professor / renter asks the owners of the house what 'the catch' is (why it's so inexpensive to rent), the response from one of the owners (who are insulted at the idea that it's a 'catch' -- their response is, 'it's our mother.' -- is that intended as the 'catch? that the house is their mother? (then the conversation shifts to that she is an eighty five year old woman, and that she stays in the upstairs room). I think there may be some symbolism here of the death-and-renewal, earth-goddess sort.

And, by the way, this is NOT a 'haunted house' but what might be described as a slightly different genre' -- a 'living house.' Not haunted, as on the changeling or The Haunting, nor 'demon possessed' as on the Amityville Horror, but a 'living house' -- this one with an appetite and a penchant to renew itself. Lots of old houses, to me, seem to have a soul and thoughts and demeanor of their own. Enjoy the renewal rites.
