Just watched possibly the worst movie ever!

My wife and I just watched "Frozen Dead. It is a 1967 Dana Andrews movie. The short explanation is that a mad scientist who was a Nazi in WWII uses the head and brain of a girl his assistant murdered to help thaw out Nazis who were frozen at the end of the war.
The official summary (below) might make the movie sound not too bad, but it was a real groaner. We kept waiting for it to get better, but it never did:
Dr. Rupert Norberg (Dana Andrews), a leading medical researcher for the Nazis, has been secretly at work in England for 20 years, learning how to reanimate a flash frozen Nazi force. He has been supported in this work with funds to cover the "castle" in which he works as well as care for his niece, Jean (Anna Palk), whose father is one of the dozen "stiffs" in his locker. He can restore the physical bodies of the soldiers but has yet to get their brains reactivated. His assistant, Carl Essen (Alan Tilvern), prematurely tells a former general (Karel Stepanek) that their goal is in sight. The general's appearance forces the assistant to push things further. Knowing that Norberg needs to study a live brain, Essen kills Elsa Tenney (Kathleen Breck), the girlfriend that Jean, has brought home for the school holidays. Then he prompts Norberg to keep the head alive for study. At the same time, Dr. Ted Roberts (Philip Gilbert) arrives from the U.S. to assist Norberg in his research. His own work has been able to keep a dog's head alive in the laboratory. Elsa's head starts sending premonitions out that Jean picks up on. Although originally sworn to secrecy, Ted falls in love with Jean and switches his allegiance to help Jean stay alive and get to Elsa.
Why would you waste your time watching something so far out there that it's not funny?
