Frankensteins Bloody Nightmare is really an experimental film disguised as a horror movie. However, horror fans (like myself) will love it because it's really creepy and disturbing.
The gore, although there is some, is fairly minimal. Instead, the film builds suspense through mood and an overall pervasive sense of dread and uneasiness. Totally unsettling, especially with a haunting soundtrack that gets its claws through your ears and into your brain -- and won't let go.
