You definitely should! Also proves my point it is not very well known. Actually the only way I found out about it, is that Stephen mentioned it in Danse Macabre! Then I first saw it on German tv, but synchronized in German which is not ideal.
The blu-ray is from Arrow Video.
Burnt Offerings | Arrow Films
But it is region B/2, so for Europe.
Arrow is a superb distributor. They include a lot of extras, and nice newly created posters, booklets with academic writing often very interesting. I buy a lot from them.
Burnt Offerings is not the best looking of their releases though. It didn't have that sharpness of blu-ray, but possibly it has to do with the way it was filmed. Seventies horrorfilms often have a sort of 'foggy' look. I think they do this with fog filters, Curtis says something like that on the audiotrack, and vaseline on the lenses. Maybe this prevents the sharpness of blu-ray to come to the fore.
I LOVE the look of seventies horrorfilms, films like this or the original Salem's Lot. They're often a little soft focused with a lot of light reflecting from surfaces.
