I get that adaptations from books to TV or movies have to change things sometimes, or they make a new character just for fun, all fine with me.
But I think one of the best/worst things is when they use a characters name with nothing of his personality whatsoever. Like you needed a character, fine allright, but why didn’t you invent a new one, you do it all the time, why use an actual book character and throw his purpose and personality out of the window.
Like Dagmar in Game of Thrones is a gigantic asshole who buys Theon out to the Boltons and gets killed by Ramsay. While Dagmar in asoiaf is one of the few Ironborn who belives in Theon, who taught Theon how to draw a bow and helps Theon with his plan to take Winterfell and is still alive and well in the books.
Or Smalljon Umber who was Robbs guard and died with him at the Red Wedding. Who sold out Rickon and Osha to Ramsay in the show.
It is all hilarious, disturbing and sad at once.
