Game of Thrones was lauded for it's gritty shocking approach to sex and death, at least in the first couple seasons, but I don't think a TV show could ever touch the harshness of the world as described in books.
I think it would have been outrageous for a different reason, but the show's scene was still uncomfortable for its lack of consent. One of the key points of that scene in the book was how cautious Drogo was to respect boundaries. In the show, the repetition of "no" was used as a command, as a denial of Daenerys' choices, and to state that her choices do not matter. In the book, the repetition of "no" was used as a question, not a command, in order to ask for consent despite a language barrier. This was used to draw a contrast between Daenerys in Westerosi society, where she had no choices of her own, and Daenerys in Dothraki society, where her choices were respected.
