“Less obvious to those unfamiliar with the story, but almost as radical an alteration, is the tone of the relationship between D’Artagnan’s friend Athos (Emmanuel Brown) and Milady de Winter (Piera Van de Wiel). Because the show puts all its chips on comic action, it misses the book’s more adult sentiments: We never get a sense of the intensity of the hatred between Athos and Milady, which is matched only by the power of their past love.”
