I felt the same about the story, but I didn't like the acting for Acier and Olga. They were both voiced by non-anime actors and sounded pretty flat most of the time. One Piece has always had a slightly cartoonish sound to the voice acting, but they both sounded too realistic and couldn't really emote well. I'm guessing they were only cast because their manager or agent was on the production committee and insisted on it.
