if Henry was that keen on book accuracy for Geralt then I have to wonder why he chose to make Geralt monosyllabic in s1 which absolutely was his choice as confirmed by Joey in a post S1 video interview and by Henry himself in a print interview; the most likely scenario is that he thought he was gonna earn a shit ton of money doing Superman (and honestly I don't even blame him for that, you can't do big pretty boy action roles forever, at some point Hollywood is gonna stop calling or you're gonna injure yourself), but making out that he sacrificed himself on the altar of book accuracy is just silly.
