This has been an unbelievable year for catalog releases and this list could very easily go into the dozens so here's a list of a just few of my favorites.
I remember paying $20.00 for multi-gen bootleg VHS with burned in Greek subs or such for some of this back in the dark ages of cult film collecting.
SATAN'S BLOOD 1978 Vinegar Syndrome Blu
Director & writer Carlos Puerto's sex & gore-filled Satanic romp has had a couple of DVD releases in the past but with a new 4K scan of the 35mm negative Vinegar Syndrome's Blu-ray brings all the skin & Satanic goings-on out in gorgeous clarity. One of the first post-Franco regime Spanish horror films that took advantage of the relaxing censorship standards, there's also was some help here production-wise from Juan Piquer Simón (PIECES) and Vinegar adds a great bunch of extras including a 45-minute Spanish documentary on the film, still gallery and best of all a commentary track by Samm Deighan and Kat Ellinger.
Along with the exploitive elements on full display, it's also a beautiful looking film filled with a moody gothic atmosphere some very creepy set design (including an unsettlingly macabre doll), and a climax that'll stick in your brain for quite a while afterward.
AN ANGEL FOR SATAN 1966 Severin Films Blu
