I've never seen ANY Frankenstein movie, but I was born at the foot of the Frankenstein Castle in Germany. They have a different story with their Frankenstein though.
The films were made in the early 30's and can be seen on You Tube https://www.bing.com/images/search?q=frankenstein&qpvt=frankenstein&form=IGRE&first=1&cw=1129&ch=414
