Nothing against this actor personally, but it doesn't fit with Robert E. Howard's character or story. Conan was from northern lands with blue eyes and dark hair so he needs to be played by someone of Nordic, Icelandic, German, Scottish or related geographical decent. Even if it's not perfect, to have someone that looks Pacific Islander doesn't fit the original character.
Poor showing...one of my favorite childhood stories.
Arnold will always be the Conan character, some things should not be re-created.
