The books still exist. Any sense of them being tarnished by association is all in the mind. Effective reading requires one to fill in the undescribed parts of a fictional world using one's imagination. It seems to be a skill that many do not possess. They lie replete on their couches gorging on pretty sounds and images but their palates are extremely choosy about the fare that they will tolerate. If one doesn't like the showrunners' vision, switch off the TV and switch on one's mind.
