Yes, indeed the story is ridiculous. Yes, every scene with the "creature" either looks like Rosey Grier with a plastic head on him or Ray Milland uncomfortably close for close-ups. But the film has a certain charm that is undeniable, due in large part to its dated 70's style, its corny almost pathetic dialogue, its incredibly cheap sets and special effects, and of course the entire premise about this two headed monstrosity. Milland and Grier manage to keep straight faces throughout the picture, as do the other thespians concerned. No small feat believe me! The chase scene of 14 police cars chasing the two headed man on a motor bike(which last over 15 minutes) is the centerpiece of the film and sets the mood, pace, and credibility of the film. If you get a chance, see this film and its trailer which is almost as good.
