Things I didn't expect
I had never read this, and I was surprised by a number of things: that we get a detailed account of the monster's learning process (which had me thinking of LLMs), that the Monster is smarter and more rhetorically savvy than Victor, and that the Monster's rhetorical skill is highlighted by Shelley (we hear of the monster's "sophistry" which then had me wondering: Is this where @sophist_monster comes from?
One last thought...this book is tale of what happens when science rejects aesthetics in the name of pure efficiency and function. If Victor had cared at all about what the monster looked like, then the entire story unfolds quite differently. The monster's hideous "countenance" (Shelley's favorite word by far, btw) is why he can't have a connection with person, regardless of how much he craves that connection.
