I've actually always been kinda bothered about people calling the daemon made of stitched together bodyparts.

It never says that in the book, and rather sounds like Frankenstein took some dead body parts, and created some material out of which he formed the body. He talked about creating the veins and muscles, you don't have to do that if you just stitch him up

Also, he's not necessarily described as handsome. He's described as having beautiful hair, but that's about it. He had yellow skin that barely covered his muscles, black lips and dull, empty eyes. I think most of his ugliness came not from individual features tho. I'd imagine the monster would fall heavily into the uncanny valley.

It's so interesting that I've stumbled upon a Frankenstein thread, considering I've read the part about his creation literally yesterday when rereading the book
