I liked both, but now that I've let it digest a bit, (Frankenstein spoilers) I do wish the film kept that the creature became very spiteful and started targeting Victor's loved ones out of revenge. I don't know if that would still work for this version of the creature, but there was more nuance in the feud from the book. I did like the change that Victor abandoned the creature not out of disgust per se, but frustration from his failure as a parent, which calls back to his daddy issues from the beginning.
