In terms of big villains on Game of Thrones, you would have to think the likes of the actors who played Ramsay Bolton and Joffrey Baratheon would probably take the brunt of the horrifying comments.
Jack Gleeson, who originated the role of Joffrey Baratheon, seems blissfully out-of-the-loop regarding GOT stuff at this point.
Hopefully, other actors who play well-hated characters on Game of Thrones have managed to avoid this disdain online–or at least not take it too much to heart.
But Iwan Rheon, who played Ramsay on the series, has been delightful and amusing when it comes to talking about playing a complete scumbag.
