Good observations here. Like you, I was amazed how quickly Frankenstein distances himself from his creation in the book.
Obviously, the movie sustains a very different tension between the two–a much slower descent into horror, as it were. I’m interested to hear what you think of Shelley’s pacing in contrast as we read the rest of the book. What is the impact of her narrative choices as we read a long story where the monster has already been unveiled and judged abhorrent?
