The creature was always supposed to be a mix of sympathetic and monstrous. He becomes a monster by turning himself implacably toward revenge, but we can sympathize with him for what sets him on that path. The entire premise rests more on Victor being a monster. I thought the movie handled both of those fairly well. There's really no living director who gets the Gothic sensibility quite as well as del Toro.

The movie removed all nuance from the story. The monster having monstrous traits is an important part of the book

I think it's less about the traits and more about the reaction to the creation.
