A successful actor, a stunningly beautiful model and… a shy geek. Yes, it's one person, namely Henry Cavill, who has a better understanding of the Witcher universe than the show's showrunner.
The portrait of the witcher he created evokes extreme emotions - some are delighted with how beautifully he conveys his character and how amazing it turns out on the screen, while others complain about the overly literal nature of the rroi, fussy facial expressions, oversized figure, etc. However, most agree with the fact that Cavill is a really interesting character who shed new light on the common image of a geek/nerd.
