This is a prime example of the type of film that haunted and disturbed me greatly when I saw it as a child. I had nightmares about a demonic Ernest Borgnine for months. Viewing it now I find it still holds up relatively well as a fairly well done 'satanic 70's horror' escapade. A disturbing nightmare of imagery and sound to invade your dreams...forever. And very impressive make-up Fx for the time. Who else grew up in the 70's haunted by the strange and dreamy horror films of the time? How does that "shape" childhood? I suppose one is influenced by whatever time they grew up in, but there was no other time like the 70's.
