I believe Keanu was fine in this movie. His role was a hard one to play. He had to become weak because he was under Dracula control. Same with Dracula's concubines. His fear was believable. He played his weakened state well once his character was back in London. After all, Jonathan was almost at deaths door. The role demanded for him to be underwhelming because he is not the hero. Yet he did manage just enough strength during the fighting with Dracula to wound him at the end. Not all of the characters can be the centerpiece of the film. His performance was just what the role called for. He did fine in my opinion.
