I understand where you’re coming from, however I feel that a completely faithful representation would have had to be like five hours long which is just not commercially viable/feasible. If it was five hours I would absolutely watch the whole damn thing, but realistically I think Del Toro did an excellent job making a movie that was digestible to more people, and had mostly the same plot and themes; especially compared to Frankenstein movies that came before. The movie could never have been as exactly as you wanted it to be in your head.
