This is the first cinematic adaptation of Mary Shelley's "Frankenstein" story, and I think it would unfair to apply a rating on a ten minute film that's well over a hundred years old. As a story its nothing special as it rapidly covers the major beats of the book. The presentation I saw it in was poor, it could do with a nice restoration as I could barely make out what was happening on screen.
In the coming years there would be films that would take "Frankenstein's" ball and run with it. And whilst it's not as revolutionary as "Birth of a Nation" or "The Cabinet of Dr, Caligari" it's still a wonderful piece of cinema history, and that alone makes it invaluable.
(It's currently on Amazon Prime UK if anyone's interested.)
