Lady Frankenstein 1972
A descendant of Frankenstein decides to carry on the family tradition by creating a new monster. He uses the damaged brain of a recently hung murderer to transplant into another rather large body. Lightning is used to bring the creature to life but also burns the poor suckers face causing him to look like chopped liver.
Immediately upon awakening the monster kills Dr. Frankenstein. But his daughter who is also a doctor decides to continue his work and she's even nuttier than her father. She decides to create a sex machine and let's just say she goes out with more than a bang.
Not great but not bad either.
